Billing for occupational therapy services in 2026 demands more than submitting visits. Medicare Part B applies a $2,480 annual KX threshold to occupational therapy, a separate $3,000 medical review trigger, and an 85 percent payment rate for assistant-delivered care, so every claim needs defensible documentation.
Our certified coders reconcile evaluation complexity, timed minutes, modifiers, and supervision rules before claims leave your clinic. Practices gain cleaner submissions, fewer costly payer rework cycles, and faster cash flow, while therapists spend their hours treating patients rather than chasing remittances, appeals, and eligibility surprises.
Medicare counts timed minutes across direct one-on-one services, then converts them to units. Eight to 22 minutes’ equals one unit, 23 to 37 equals two, 38 to 52 equals three, 53 to 67 equals four.
The 8-minute rule occupational therapy clinics follow also governs mixed sessions. When multiple services fall short individually, the remaining minutes are assigned to the service with the most time that prevents overbilling during audits and denials.
Untimed codes such as evaluations 97165 through 97168 do not count toward timed totals, but they still affect documentation. Start and stop times, treatment details, and therapist signatures must evidently support every individual billed unit.
Unit Conversion | Mixed Services | Timed Codes | Audit Defense
Every minute documented becomes a unit protected from costly denial.
Each practice type needs correct enrollment details that include the occupational therapy taxonomy code 225X00000X for therapists and 224Z00000X for assistants, so claims route precisely and credentialing stays allied across payers.

As an occupational therapy billing company, HMS USA pairs credentialed coders with payer-specific edits that give your clinic transparent reporting, dedicated account managers, and reimbursement strategies built around current Medicare therapy policies and commercial contract authenticities.
Compliance-first billing that quickens your clinic revenue.
Our clinically trained coders understand treatment notes, plan-of-care certifications, and progress reports, so documentation gaps are corrected before submission that protect both your revenue and your compliance standing with every single payer.
Common therapy denials stem from missing KX modifiers above $2,480, absent GO therapy modifiers, unproven timed units, expired plan-of-care certifications, and eligibility errors. We analyze remittance codes, precise root causes, file appeals within strict payer deadlines, and track denial trends, so repeat denials fall and beforehand lost reimbursement payments return.
From eligibility verification to payment posting, we manage occupational therapy billing codes, modifiers, and payer rules that give practices foreseeable cash flow, audit-ready records, and assessable revenue improvement every single month.
We confirm Part B, Medicaid, and commercial coverage, visit limits, deductibles, and authorizations before the first appointment.
We request, track, and renew approvals, document medical necessity, and monitor authorized visits so care continues without interruption.
Coders match CPT codes such as 97530 and 97110 to documentation, apply GO modifiers, and confirm timed units against recorded minutes.
We apply KX above $2,480, CO for assistant-delivered care paid at 85 percent, and modifier 59 when edits necessitate distinct separation.
Claims are cleaned against NCCI edits and payer rules, then submitted electronically within days, well inside Medicare's twelve-month filing limit.
Every remittance and ERA is posted exactly, underpayments are compared against contracted rates, and patient balances move sharp to reports.
Root-cause analysis, amended resubmissions, and appeal letters citing documentation and policy recover payments and prevent denials from recurring.
Monthly dashboards display clean claim rate, days in AR, denial reasons, and threshold exposure, that enable smoother payer agreement decisions.
Occupational therapy assessments apply 97165 for low complexity, 97166 for moderate, and 97167 for high complexity, whereas 97168 covers re-evaluation. Complication depends on occupational profile, performance deficits, and clinical decision-making, and each valuation must be documented carefully to support the designated level and resulting payment.
Timed codes like 97110, 97530, and 97140 are billed in 15-minute units. Medicare totals all timed minutes for the day, converts them using the eight-minute threshold, and distributes units across services, whereas untimed codes, such as evaluations, are billed once per session, irrespective of duration.
For 2026, the KX modifier is requisite once a patient’s occupational therapy services exceed $2,480 in a calendar year. It demonstrates that continued care is medically necessary, and claims lacking it above the threshold are denied, while $3,000 makes claims suitable for targeted medical assessment.
Yes. Services provided in whole or in part by an occupational therapy assistant need the CO modifier and are paid at 85 percent of the fee schedule. The reduction applies when the assistant delivers more than ten percent of a service, so minute tracking matters.
We authenticate eligibility and authorizations before visits, audit notes for medical necessity, monitor KX thresholds, scrub claims against payer edits, and cautiously analyze every single denial code. This prevention-plus-appeal approach dependably lifts first-pass acceptance rates and importantly shortens the time between treatment and final payment.
We work with Medicare, Medicaid, TRICARE, workers’ compensation, and commercial plans, and more popular therapy EHR and practice management platforms. Our committed team adapts to your existing workflows, so onboarding is rapid, smooth, and disruption-free, and you keep full reflectiveness into every claim, payment, and denial.
