According to CMS national health expenditure information, hospital care makes up the biggest portion of U.S. health care spending. U.S. healthcare spending reached $5.3 trillion in 2024, growing 7.2% from 2023, while hospital care spending totaled $1.63 trillion. Small drips in billing can quickly accumulate at such large numbers. The mistakes made in coding, charge leakage, delayed claims, and inadequate follow-ups gradually erode profit margins which some hospitals cannot afford.
Through HMS USA, hospitals, healthcare networks, and employed physician practices can manage their complete revenue cycle through coders who are certified, savvy billers, and denial management. Our hospital billing services include charge entry, claim processing in UB-04 and CMS-1500 forms, payment posting, appeals and outstanding balances from the patients. All this is done while keeping up to CMS, HIPAA, and commercial payers guidelines. In doing so, we support you to keep your clinical staff concentrated on providing care.
In-house medical billing is getting more difficult each year. Insurance companies make frequent changes to their policies. Annually updated codes CPT, HCPCS, and ICD-10-CM need additional training of coders. Turnover of staff creates vacancies that take months to fill. Software and administrative costs also create difficulties for many hospitals.
Outsourcing is the transformation of an uncertain fixed cost into a performance-related cost. Rather than employing and training your own department, you are getting an entire group that is trained in inpatient DRG classification and outpatient APC classification and specific payer edits. Outsourcing also enjoys government support. The latest guidelines issued by CMS on prior authorization and electronic exchange impose a higher technical standard for every billing office.
Lower administrative overhead per claim.
Faster adaptation to payer and CMS rule changes.
Scalable staffing during volume spikes.
Dedicated audit and compliance support.
HMS USA’s billing and collections processes start from patient registration until the resolution of accounts.

This makes the hospital billing and collection services provide management with an accountable partner.

Hospitalist and physician service codes have always been heavily audited when billing the medical practice of hospitals. Following the 2023 CPT revamp of inpatient and observation codes, level determination will be based on the type of medical decision-making or total time on the day of the service delivery. Teams with old mindsets are likely to miss code levels. The notes generated by our hospitalists are consistent with the latest guidelines on initial, follow-up, and discharge care (CPT Codes 99221-99223, 99231-99233, 99238-99239 respectively). Our medical billing services for hospitals also cover split or shared visits, critical care time, prolonged services, and observation status. Physicians get prompt feedback to help improve their documentation process. Since we provide physician billing services for hospitals as well as facility billing services, any discrepancies between the two get sorted out before the claim is actually filed.

CDC’s survey estimated about 155 million emergency departments handle visits in 2022. Each one carries unusual billing complexity. Care is delivered before insurance is verified, patients often cannot provide complete information, and EMTALA requires screening and stabilization regardless of ability to pay. Claims frequently involve multiple professionals, imaging, labs, and procedures that must be bundled correctly.
Our emergency medicine billing services for large hospitals focus on accurate E/M leveling (99281–99285), critical care documentation, procedure and modifier use, and facility-professional coordination. We also handle No Surprises Act requirements, which protect patients from unexpected out-of-network emergency bills and require careful payment dispute handling between providers and plans. Our team follows up on registration gaps, secondary coverage, and trauma and liability cases that standard workflows miss.

Denied and delayed claims are one of the most persistent threats to hospital cash flow. Federal oversight shows why careful follow-up matters. A Department of Health and Human Services Office of Inspector General review of Medicare Advantage found that 13% of prior authorization denials and 18% of payment denials met Medicare coverage rules and should have been approved. Hospitals that appeal systematically recover revenue others write off.
Our hospital accounts receivable solutions begin with root-cause analysis, not just resubmission. We sort accounts by age, balance, payer, and denial reason, and we assign each to a specialist with the right payer knowledge. Appeals include clinical rationale, plan policy references, and timely filing evidence.

Billing accuracy depends on how well your systems communicate. Charges, orders, registration, and clinical documentation all live in different modules, and gaps between them cause rework. We work inside your existing EHR and billing in the hospital management system rather than forcing a platform change, and we configure edits and work queues to fit your payer mix.
Compliance is built into every step. We follow HIPAA privacy and security requirements and maintain audit trails for coding decisions. We also monitor federal updates such as CMS price transparency requirements and prior authorization interoperability rules, which are phasing in through 2027. Cyber risk is a real concern as well, since HHS breach reports consistently show hundreds of large healthcare data incidents each year. Our access controls, encryption, and role-based permissions are designed to keep patient data protected.
Connect EHR, practice management, and billing workflows.
Protect patient information through access controls and encryption.
Track CMS updates and evolving healthcare billing requirements.
Maintain clear records of coding decisions and billing activities.
Configure payer-specific edits and work queues for accuracy.
Support HIPAA-aligned processes across documentation workflows.
Your billing process will be quantifiable. We will base the hospital’s billing management on the same critical performance indicators that the Chief Financial Officer follows each month.
These are based on standards used within industries and depend on the payers served, service lines, and current level of performance. At the time of onboarding, we establish your current benchmarks, identify weaknesses, and implement a 90-day improvement plan. In the monthly meetings, progress is analyzed in terms of payer, department, and denial category so the executives know which sources contribute to revenues or losses. When there is poor performance, we explain the cause and the correction needed instead of citing general averages.
Our teams understand facility and professional billing, DRG and APC payment systems.
You get direct access to claim status, denial trends, and collections data without waiting.
Your hospitals do not require one more vendor who will report and hope for the best. What your hospitals require is a hospital medical billing service from a company that functions like an extension of your finance department. We also offer you a seamless onboarding process with well-defined milestones so that your cash flow remains safe while we onboard with you. Our aim is to create a partnership based on results.
Our dedicated accountable manager coordinates with coders, billers, and appeals staff.
Regular internal audits and ongoing education keep our work aligned with current rules.
Schedule a short consultation and see how HMS USA can lift your hospital’s collections quickly.
These include patient registration, insurance verification, charge capture, coding, claim submission, payment posting, denial management, appeals, and patient collection. The aim is to process each account from service through full payment effectively and efficiently while complying with the requirements of the payer and the government.
By outsourcing, hospitals get professional coding staff, payer-specific processes, and follow-up, all without having to hire any staff members. Clean claims, reduced denials, and rapid handling of appeals can reduce turnaround time for payments. The other advantage is adaptability to changes in regulations and payer policies.
Yes. We operate within your existing EHR and practice management system, so you will not be burdened with any costly migration. Our experts adjust according to your charge capture, claim edit, and reporting systems to maintain smooth operation for you.
Our focus is on the front-end, as denials are first generated here. Checking eligibility, monitoring authorizations, reviewing documentation, and claim scrubbing can help detect problems before they arise. Once denials happen, we will document the underlying cause, appeal with clinical evidence, and learn from them.
Yes. We handle facility billing and professional billing for hospitalists, emergency physicians, and other hospitalists. Dealing with both sides allows us to match up statuses, modifiers, and documentation, which helps to avoid conflicts that could cause payer denials or audits.
The timeline will vary according to the size of the hospital, its system, and whether there is any backlog in the system. The majority of on-boarding projects follow a step-by-step process that includes establishing access, defining processes, generating base-line reporting, and training the employees.
