You are busy, claims are going out, and payments are coming in. Still, something seems amiss with your collections. Your operating rooms are busy, claims are going out, and payments are coming in, but your collections don’t reflect all the work your anesthesia team performs. Some cases don’t make it to the billing process. Others are paid below the expected allowable. A clean-looking dashboard can cover both.
Anesthesia RCM fills those gaps. It allows you to track each case from the facility record to the claim, payment, and final resolution of the account. The goal is not to simply generate more claims. It is to collect the amounts rightfully owed, verify the support of all services billed, and understand why legitimate claims are denied.
Anesthesia RCM, defined simply
Anesthesia RCM is the integration of patient information, provider enrollment and assigned identifiers, clinical documentation, coding, claims, payments, and account follow up. It provides base units, modifiers, and rules to practices to identify why adjustments were made to charges, determine the root cause of claim denials, validate reimbursement levels, and manage patient financial responsibility.
Billing is one part of the process. Revenue cycle management encompasses the process leading up to the creation of a claim and the process that follows a claim payment. Taking a broader scope on the process is necessary to assist in the investigation of missing claims, underpayment claims, and claims that are unjustifiably denied.
Anesthesia reimbursement depends on more than a procedure code
There are several specialties that rely on time-based billing, but anesthesia specialties utilize time as well as base units and provider relationships, in addition to payer adjustments. A valid code doesn’t mean the entire claim is correct.
Base units, anesthesia time units, conversion factors
Base units are the value assigned to the anesthesia procedure. Time units are the duration for which anesthesia care was provided, within the payers’ adjustment rules. Conversion factors are the multiplying factors which, once applied to the appropriate units, determine the allowable amount.
A simplified calculation is as follows:
Expected allowable amount = eligible units x applicable conversion factor, with required care model or other payment adjustments.
For example, let’s say there is a commercial contract that recognizes 6 base units, 90 anesthesia minutes, a 15-minute time unit, and a $60 conversion factor. In the absence of any additional eligible units or payment reductions, the calculation would be 12 units x $60 = $720.
This is an example and not a quote. It is important to note the rounding rules and other payment provisions in each contract. ASA’s (the American Society of Anesthesiologists) payment advice states that when completing payment calculations, providers should review the contract language and payment provisions rather than assuming or applying the calculations across all payers.
Also separate allowance from insurer payment. A $720 allowance doesn’t mean the insurer owes $720. A difference could be due to valid patient cost sharing or adjustments.
The care model changes the claim
A service performed personally by a practitioner is different than a service medically directed by a practitioner. Documentation needs to explain participation and the role of each practitioner, as well as support the use of the reported modifiers.
Practice managers need to be able to replicate the clinical arrangement on the billing system. Procedures coded to the correct specialty may not represent proper clinical and financial entity separation if the relationship between providers is assumed and predefined.
Claims for professional anesthesia services need to be clearly distinguishable from facility claims. Similar separations need to occur for hospital support and staffing agreements. Combining revenue streams into a single number makes it challenging for managers and administrators to perform an accurate and thorough assessment of billing performance.
Build the workflow around complete, traceable cases
The most operable question is: can your team describe what happened to every completed case? Effective revenue cycle management for anesthesiology preserves that connection across the departments instead of treating each handoff as someone else’s responsibility.
Scheduling and financial clearance
Anesthesia Medical Billing Services are only possible when the payer and procedure information is accurate along with facility, insurance plan and anticipated participating providers. The patient insurance information has to be verified by the billing team prior to the procedure, and it should also confirm whether an authorization is required for these billed anesthesia services. Just because the surgeon has been approved, does not mean that anesthesia is automatically included. The team should also ensure there is a process to receive changes, cancellations and updates on the schedule from facility so that claims can be billed accurately and on time. Staff need to detail what is confirmed and point out what coverage remains. But no financial or administrative requirements should ever delay urgent or value-based care delivery.
Credentialing and payer enrollment
Payer enrollment does not imply participation in a network. Anesthesia privileging and payer participation are independent processes. The approval of a facility does not infer network participation. An individual provider’s payer status may not reflect the correct group.
There should be a confirmed register describing the participant provider-by-payer covering individual enrollment, group association, location and participation as well as any constraints affecting claim submission. Provide confirmed, as opposed to tentative, information to billing staff.
Investigate the actual enrollment and contract record if a payer rejects a provider relationship. Don’t use a different practitioner ID to move a claim through. Document unclear cases and establish a controlled exception queue with an owner and an escalation path.
Capture charges and reconcile facility
Compare the completed case list submitted by the facility with the anesthesia records and the billing inventory. Every service should have a disposition.
A missing claim will not appear on a denial report. That is why charge capture needs to have its own control.
Use reliable case identifiers and reconcile at the encounter level. One case can yield multiple billable professional services. Combining records can conceal an unbilled case.
Documentation and Coding
Verify the supporting record for the service, procedure, diagnosis, anesthesia, time, practitioner, and reportability. For unclear information, give it a query and document the reason for the clinician’s absence.
The ASA crosswalk is a resource for surgical-procedural anesthesia coding, but it is not a substitute for reviewing the actual surgical procedure. There are other factors to consider when analyzing the final service versus the planned or scheduled procedure. Coding for one procedure can also affect coding for other procedures.
Make your coding reviews and corrections traceable. Your reviewer should be able to identify the supporting record, the rule, and the reason for the correction. A claim that passes an edit is not as valuable as an explanation justifying the change.
Track submissions and acceptances
Validate patient data, provider identifiers, payer routing, facility info, diagnoses, procedure codes, modifiers and the requirements of the format of the claim. Track both responses from the clearinghouse and acknowledgements from payers.
Transmission doesn’t always equal acceptance. A batch of claims exported from the system can look complete, but individual claims in the batch can still be rejected. To improve process effectiveness, clear work assignments for claims that have been rejected are required.
Retain filing and appeal requirements on the account. Corrections to claims should be maintained and reference the original claim. Uncontrolled claim duplication should be avoided.
Posting payments and resolving accounts
Post payments and patient responsibility, adjustment codes and explanations of benefits to the appropriate claim line. Reconcile the electronic remittance advice to the deposit to ensure the accounting records agree with the claim ledger.
Test to make sure the account has really been resolved. A post-payment claim can still require an investigation to determine if the claim was overpaid or underpaid. There can also be a requirement for clarification of the patient’s responsibility.
Protect time documentation without inventing billable minutes
There are a number of obstacles related to time in other specialties. For example, the entries that represent the start and stop of an event may reflect different clinical events. A misaligned interface may capture an operating room (OR) timestamp that is different from the anesthesia timestamp.
CMS defines reportable anesthesia time as the time the anesthesia care provider is present for the preparation of the patient for anesthesia and the time the patient is prepared to enter the operating room or equivalent area and is ready to safely enter the post-operative care area. If the patient is under Medicare, the actual time is reported; the contractor converts the time to the nearest 15 minutes using prescribed rounding.
What matters the most is that your internal controls flag issues. Units should not automatically be increased to cover for missing endpoints. There have to be procedures in place to investigate the reason for the issue.
A record should never automatically be extended to represent the average duration of the procedure. Corrections should not be made based on assumption of the duration of a previous case. There needs to be an appropriate process to document the correction and an audit trail to explain the change retrospectively.
There needs to be a process in place to explicitly capture a change in provider and process an interruption in care. An interruption should not result in duplicate charges for a service.
A last resort should be to test the interface itself. There may be issues within a clinical application that store time in minutes, but a billing application may be configured to interpret the data in units. To ensure an interface doesn’t generate a materially incorrect claim, sample cases should be traced throughout the transfer.
Match modifiers to the documented care arrangement
Modifier selection should not describe the service, but instead reflect how the payment looks. Treat the records of the physician and qualified non-physician in the same manner, if the care model requires it.
Common payment and informational modifiers
In general, the important distinctions include:
AA: personally performed anesthesiologist services.
QK: Physician medical direction of two, three, or four concurrent anesthesia cases involving qualified individuals.
QY: Anesthesiologist medical direction of one qualified nonphysician anesthetist.
QX: The service of a qualified nonphysician anesthetist that is medically directed.
QZ: CRNA services in the absence of physician medical direction.
AD: Physician medical supervision of more than four concurrent anesthesia cases.
QS: An informational modifier identifying monitored anesthesia care, and should not be used in lieu of the appropriate payment modifier.
Use the payer’s instructions for the actual case, including any MAC-related reporting requirements, and address state practice and facility policy considerations as applicable. A billing modifier does not establish clinical permission to practice.
Medical direction is more than a signature
CMS conditions for medical direction include evaluation and anesthesia plan, participating in demanding portions of the care, qualified personnel, monitoring, availability for emergencies and post-anesthesia care. A signature does not demonstrate that these responsibilities were met.
Concurrency review should consider all relevant, overlapping assignments (including assignments received from multiple facilities), not just assignments already received from one facility. Missing records can distort a provider’s workload.
When qualifying Medicare medical-direction payments apply, each recipient is normally granted an allowance based on half the personally performed amount. That doesn’t mean you have lost half of the group’s reimbursement. It means both claims and their expected allowances should be reviewed.
Don’t assume you will receive payment by changing modifiers if the record lacks support for medical direction. Refer the case for compliance review and follow the correct rules for the actual situation.
Keep unusual staffing arrangements out of your default workflows
Teaching cases, student participation, and relief and other practitioner situations, and overlapping assignments warrant closer review. They shouldn’t gain a modifier by default, merely because the same modifier worked in a different circumstance.
Have a specialist review the case and ensure they can see the entire record. The software may identify inconsistencies, but it can not confirm clinical actions were taken. The specialist needs the authority to retain the claim and request clarification.
Capture legitimate complexity without adding unsupported charges
Physical status and qualifying circumstances can impact reporting, but, ASA states, Medicare will not pay additional amounts for these codes, and commercial coverage will depend on the payer contract.
Total body hypothermia (99116) and controlled hypotension (99135) are conceptually and functionally different. Controlled hypotension is the lowering of an individual’s blood pressure via the use of specific pharmacologic or non-pharmacologic techniques. A spontaneously low body temperature would not qualify for total body hypothermia.
Considering payer rules and documentation together is key. Demographics may warrant a case review, but a case review and determination should not dictate the addition of a payment add-on code. Generally, the primary anesthesia code would not be payable and other exclusions would need to be taken into account.
Bundling is important when assessing payment. Just because one anesthetic service is complete and another service is initiated, it does not mean that service is also payable. This would also hold true for postoperative pain management. Review the rules and assess whether NCCI editing would also apply.
For management reporting, a distinction should be made between a legitimate service that has been appropriately excluded, and a charge that should have been billed, but was not. A dashboard may state that unbilled charges equal lost revenue, which can negatively incentivize employees and promote inappropriate behavior.
Separate missed charges, rejections, denials, and underpayments
These categories can all lessen collections, but bundling them into one queue conceals the solution.
A missed charge requires reconciliation. A rejected claim requires correction of an acceptance problem. An adjudicated denial requires a reason specific response. An underpayment requires comparison to the valid expected allowance.
Determine the reason for claim denials
Consider the adjustment and remark codes used by the payer when reviewing the claim and the supporting documentation. Effective categories include medical necessity, adequacy of documentation, timeliness and adequacy of authorization, eligibility, enrollment, medical record duplication, completeness of record and filing requirements.
The cause should explain the operational problem. “Payer denied” does not address the operational cause. “Group association is missing in the payer enrollment record” is a more operational way of saying the same thing.
Both an account action and prevention action should be taken
The person who is appealing a claim may not be the person who is addressing the broken facility interface or the inaccurate provider roster.
Construct an appeal based upon the evidence
An appeal should include a copy of the policy or contract language and a statement regarding the reason the claim is being appealed. Language related to medical necessity will not resolve an enrollment problem.
Consider the route required by the payer. Sending the right evidence through the wrong process can leave the balance unresolved.
Be sure to document the submission reference, the amount disputed, the correction requested, and the next action to be taken. It is important to track recoveries separately from routine payments to determine if the effort expended by the practice to make a balance payment recovered the balance.
Follow up on Accounts Receivable (AR) based upon the risk and the potential recoverability
The size of the balance is important, but it should not be the only consideration. Consider other factors including the filing exposure, the nature of the payer, the requirements of an appeal, and the evidence available to support recovery.
A group of smaller balances with the same defect may warrant attention over a single larger balance with no payment basis.
Insured patient balances, credit balances, and other balances that are a result of claims processing issues have different resolution avenues, and should be considered individually from other balances.
Compare payments with contracts, not just billed charges
Payment system deviations can occur in either direction. Even if a payer pays exactly what its system calculated, it is still possible for the payment to be less than your contract allows. Without an expected payment model, that difference may disappear into contractual adjustments.
Continue to document payer references that include conversion factors, unit methodology, modifier treatment, covered add-ons, provider participation, and other relevant reimbursement factors. Use the contract version applicable to the service, rather than assume one contract is applicable to all accounts.
For a simplified example, assume an allowed amount is $600, the payer pays $430, and the patient responsibility is $120. With those payments, there is a total of $550. The remaining $50 is an unexplained difference, and should be investigated.
Do not shift that difference to the patient. First, determine if there was an underpayment. For example, was there a valid coordination of benefits, or was the payer’s contract interpretation incorrect?
Report confimed differences separate from suspected differences. An opportunity is not cash, and a disputed amount is not necessarily uncollectible. Making this distinction keeps your revenue projections more realistic.
Reducing the A/R balance by unsupported adjustments improves a practice’s financial position as much as uncollected A/R. Define who can adjust, what is needed to support the adjustment, and how the reason is communicated. Supporting adjustments improves the financial position of the practice, but reduces collections, which is the purpose of a medical practice.
Keep patients out of payer reimbursement disputes
Patients have questions about why there’s a separate anesthesia bill from their hospital and surgeon’s bill. Staff can address these questions with clear billing statements. They can also handle these inquiries with courtesy and professionalism, without referring every question to collections.
Discuss services, providers, and the processing and approving of insurance claims. Clarify the patient’s financial responsibility and the available financial assistance. Provide staff with a mechanism to halt collection activities during the review of a good faith billing dispute.
Properly protect patients from surprise billing
Patients are protected from surprise billing for services subject to the No Surprises Act, regardless of whether the group is in agreement with the payer. In a protected non-emergency situation at an in-network facility, anesthesia is an ancillary service and the notice-and-consent exception does not apply.
An Exception form signed by the patient does not allow prohibited balance billing. Review the relevant federal protections, state requirements and plan sponsor rules prior to assigning responsibility.
Treat Independent Dispute Resolution (IDR) as a separate process
Federal Independent Dispute Resolution may apply to eligible out-of-network payment disputes, provided that the required negotiation process has occurred. It does not replace normal claim adjustment, and does not apply to all out-of-network services.
Ensure the dispute amount is documented and separated from other payment. A ruling in favor of the patient does not mean the collected amount was actually paid.
Separate negotiations between an insurance plan and a healthcare provider from negotiations between a healthcare provider and patient. Staff should not use unresolved contract reimbursement as a reason to demand patient payment that is not owed.
Track KPIs that explain the problem
Anesthesia RCM reporting should show whether cases are captured, claims are supported, and accounts are resolved correctly. Collections alone cannot answer those questions. Use consistent definitions and compare similar payer, facility, and care-model segments.
| KPI | Practical definition | Decision it supports |
|---|---|---|
| Case reconciliation rate | Completed cases with a documented billing disposition divided by completed cases reviewed | Locate missing records or charges without counting paired claims as separate cases |
| Charge lag | Interval between service completion and charge entry | Identify facility handoff and documentation bottlenecks |
| First-pass acceptance rate | Initial claims accepted without rejection divided by initial claims submitted | Improve claim preparation; acceptance does not establish payment |
| Initial denial rate | Claims denied on initial adjudication divided by initially adjudicated claims | Identify payer and operational defects; separately report denied dollars |
| Net collection rate | Collections net of refunds divided by charges less legitimate contractual adjustments, using a defined matching basis | Assess collection effectiveness without hiding avoidable losses in adjustments |
| Expected-allowance variance | Supported expected allowance compared with payer allowance | Detect potential underpayments without confusing patient responsibility with a payer shortfall |
| Days in A/R | Receivables divided by average daily charges under a consistent method | Assess collection speed while checking for distortions from growth or write-offs |
| Aged A/R share | Receivables beyond the selected aging threshold divided by total receivables | Focus escalation by payer, cause, and recoverability |
| Documentation exception rate | Reviewed cases requiring clarification divided by cases reviewed | Direct provider education and template corrections |
| Denial recovery rate | Recovered dollars divided by the defined denied-dollar cohort | Evaluate recovery work without mixing unrelated collections |
Set targets from a reliable baseline and a comparable practice profile. A universal benchmark can mislead when groups have different payer mixes, procedures, or patient-responsibility exposure.
Be especially careful with net collection rate. If an avoidable denial is reclassified as a contractual adjustment, the denominator can shrink and make performance appear stronger. Show adjustment categories alongside the percentage.
Every exception should lead to a decision: who owns it, what evidence is missing, and what action will resolve it? Reporting without ownership is just a more attractive way to display unresolved work.
Choose technology that exposes exceptions
Automation links the clinical record, building, practice, clearinghouse, and payment records. It should find discrepancies and retain source information so a reviewer can identify the issue.
View a case with time missing, a corrected procedure, a provider handoff, and underpayment by a payer. Demonstrations using complete records won’t show how the system processes the exceptions you identify.
Test transactions at the latency of your system. Review the mappings for minutes, units, modifiers, provider identifiers, and facility locations. Confirm that failed imports or other exceptions result in an alert, and that retransmission of a transaction doesn’t result in a duplicate claim.
Relying on AI coding or appeal tools to suggest policy language without human review is unacceptable. Tools to assist coding and appeals should suggest additions to the record and not explain, reconstruct, or fill in missing information. They also should not suggest diagnoses. Keep an audit trail of reviewer decisions and final submissions.
Ensure processes, procedures, and technologies also protect access to data. Review the business associate agreement, if applicable, as well as role permissions. Ensure your group can maintain meaningfully access its data and reports.
Compare in-house and outsourced models honestly
The choice isn’t between an internal team that cares and a vendor that has software. Either model can work. The deciding factors are specialty competence, reliable coverage, transparent reporting, and the ability to correct problems across the full workflow.
| Consideration | In-house billing | Outsourced anesthesia billing |
|---|---|---|
| Specialty expertise | Built through recruiting, training, and retained knowledge | Must be demonstrated by the assigned team, not just marketing |
| Staffing coverage | Practice arranges backup and workload capacity | Contract should specify coverage and escalation responsibility |
| Technology | Practice selects, supports, and funds the tools | Confirm integrations, additional fees, and data ownership |
| Clinical coordination | Direct access can simplify documentation queries | Requires named facility and clinical contacts |
| Coding oversight | Internal audit capacity must be maintained | Ask who audits work and how findings reach your leadership |
| Cost | Include payroll, benefits, systems, supervision, and rework | Include fees, setup, exclusions, legacy A/R, and transition costs |
| Reporting | Practice controls design and data access | Require claim-level access, definitions, and export rights |
| Growth | Capacity depends on hiring and process strength | Verify the vendor can support added facilities and care models |
A hybrid arrangement can also work. You might retain clinical queries and financial oversight while delegating coding audits, claim follow-up, or selected payer problems. Specify ownership carefully so neither team assumes the other is handling an exception.
Evaluate cost per resolved case and the quality of resolution, not just the quoted collection percentage. A lower fee doesn’t help if underpayments are ignored or the practice must supply substantial unpriced administrative work.
Make vendor selection an evidence-based exercise
Review a prospective partner’s process by having them walk you through an example using anonymized data. A credible Anesthesia RCM proposal should describe the process, the evidence, and the limitations of the service.
Use the checklist below:
- Who is the coding lead? The account manager? The escalation contact?
- Are there examples of completed case reconciliations? An unmatched case queue?
- Are there queries and documentation supporting time validation exceptions?
- How do they reconcile concurrency and paired practitioner claims?
- What is a sample of underpayment analysis tied to a contract provision?
- Are there examples of denial reports that break down root causes?
- What is the responsibility for credit balances? Credentialing and contracting? Patient questions?
- What services are included? What services are billed separately?
- What are implementation acceptance tests? What is the data ownership model? What is the exit assistance process?
What performance claims are made? What was the population? What were the metrics? Were refunds, adjustments, patient balances and unresolved claims included? A precise answer is better than a big number.
What is a sample governance agenda? What are exceptions, recurring defects and financial exposure? What involves your input? A nice looking collections report doesn’t represent the status of the working relationship and the willingness to bring up the difficult issues.
Follow one illustrative group through the problem
Consider an anesthesia group serving 3 facilities. Again, this is a hypothetical case, and not a representative client example or anticipated financial result.
From the group’s facility records, there are 1,000 completed cases, but only 970 have a documented billing disposition. The first opportunity, therefore, is only 30 cases and not assumed dollar recovery. Some may need a records request, some may already be represented by another identifier, and/or others may have a legitimate non-billable reason for the absence.
The review also identified 50 adjudicated claims with an assumed $80 shortfall against expected allowance. This represents $4,000 of variance that requires confirmation and explanation. It does not demonstrate $4,000 will be ultimately recovered.
Another group of claims contained physicians and CRNAs payments that were evaluated independently. Reconciliation showed that some apparent shortfalls disappear when both parts are evaluated together. The remaining claims require further analysis.
The best practice is to follow the data and reconcile missing cases, validate contract variances and fix the data handoffs that caused the variance.
Leadership tracks confirmed recovery, potential opportunity and supports expected recovery independently. Unsupported expected recoveries are excluded from collection forecasts.
The takeaway is to follow the data before making assumptions about dollar recoveries. Often the case may exist and the claim may be correct, but the expected payment may not exist for a myriad of legitimate reasons.
Improve the process in controlled stages
Start by creating a realistic representation of your workflow with the people that actually perform the work. This includes locating the entrance points for the records, who can correct the records, the systems that provide the records, and how do they escalate, and address unresolved issues.
Select an atypical sample to include a range of facilities, payers, and types of care delivered. Evaluate cases where services have been rendered, but the case has not been billed, as well as paid claims and claims denials. Denials should also be included, as they represent a claim that has been paid without being formally adjudicated.
Focus on errors that represent the highest potential financial loss and risk of noncompliance. Each defect should be prioritized, assigned to an owner, and have a definition of what would constitute a satisfactory remedy (i.e. acceptance criteria).
Ensure that staff understands the purpose and rationale of the new workflow. They should be able to identify and investigate exceptions, and justify decision to adjust claims.
Establish staff ownership for all active claims and adjudication (appeals) processes, credit balances, and remittance advices, and verify that an adequate inventory is provided during a transition. It is also important to ensure that ownership for the inventory is not given to both parties.
Ensure that the management structure facilitates integration and communication between clinical, billing, credentialing and finance staff. Reimbursement issues may require a facility process change, not a billing process change.
Frequently asked questions
What does anesthesia revenue cycle management include?
It includes financial clearance, provider enrollment coordination, case reconciliation, documentation review, coding, claim submission, payment posting, denials, underpayment review, and patient accounts. Practice management and accounting may interact with these functions, but they are separate services unless the agreement explicitly includes them.
How are anesthesia time units calculated?
They are calculated from supported anesthesia duration using the applicable payer methodology. Medicare uses actual reported minutes and a 15-minute unit with prescribed rounding. Commercial rules can differ. Preserve the source minutes and verify the payer configuration instead of imposing one universal rounding rule.
What do QK, QX, QY, and QZ indicate?
They describe different practitioner arrangements. QK and QY identify physician medical direction configurations, QX identifies the medically directed qualified nonphysician service, and QZ identifies CRNA service without physician medical direction. Documentation and payer requirements determine the correct choice; they aren’t interchangeable payment options.
Why can a paid anesthesia claim still need review?
A payment may reflect an incorrect allowance, missing claim component, improper adjustment, or unresolved secondary coverage. Compare the adjudication with the supported expected amount and valid patient responsibility. Money arriving doesn’t establish that the account is complete or that the contract was applied correctly.
Should an anesthesia group outsource its billing?
Consider outsourcing when specialty expertise, staffing coverage, reporting, or exception handling cannot support the practice’s needs. Compare evidence from the internal operation with a vendor’s demonstrated capabilities and total costs. Keep oversight, data access, and clinical accountability clear regardless of who performs the billing work.
Can better billing guarantee higher collections?
No. Improved controls can identify correctable losses, but results depend on documentation, coverage, contracts, payer decisions, and recoverability. The right goal is accurate, defensible reimbursement. Unsupported extra units or inappropriate patient billing are not legitimate ways to improve financial performance.
Earn confidence in the numbers behind your practice
With Anesthesia RCM, you should be able to explain each case and each claim, as well as the status of each remaining balance. You shouldn’t need to speculate whether weak collections reflect missing records, inadequate coding, payer behavior, accounting adjustments, or some combination of the above.
Begin with a focused look at case reconciliation, as well as documentation and expected payment exceptions. Regardless of whether you enhance your internal resources or engage a billing partner, ask for an explanation of the problem as well as a plan to address it. That is an appropriate starting point for a service conversation, and it will help you avoid relying on assurances that your data will not and should not support.
