How We Help
What Our Occupational Therapy Billing Team Actually Does
Most OT practices do not lose revenue because care was not delivered. They lose it because a GO modifier was missing, a note supported a lower evaluation complexity than what was billed, or eligibility was never confirmed before the first visit. We build billing workflows around exactly where occupational therapy claims break down. Coders trained specifically in OT documentation calculate timed units against the eight minute rule, match evaluation codes to the deficits actually recorded in the note, and place GO, CO, and KX modifiers correctly before a claim ever reaches a payer. Your team stays focused on treatment planning. We stay focused on getting every clean claim out the first time and chasing the ones that are not.

Certified Medical Coders
Nationwide Payer Coverage
95%+ of OT claims go out clean on the first submission.
Average claim turnaround of 48 hours from documentation to submission.
Practices see an average 30% increase in collected revenue after transition.
AR stays under 30 days on average instead of aging past filing windows.
Full Scope of Work
Full Cycle Revenue Management for Occupational Therapy Claims
Billing for occupational therapy touches more than claim submission. Every stage below is handled as one connected workflow instead of a series of disconnected handoffs.
Eligibility and Benefit Verification
Prior Authorization Tracking
Manages Medicare Advantage and commercial authorization requests for OT plans of care and tracks them against current payer response windows.
Evaluation and Timed Unit Coding
Matches evaluation complexity to the deficits documented in the note and calculates every timed unit against the eight minute rule.
Claim Scrubbing and Submission
GO, CO, KX, and NCCI override modifiers are reviewed and placed correctly before each claim goes out electronically.
Denial Management and Appeals
Every denial is coded by reason, with clinical appeals built around the payer’s actual stated criteria.
Accounts Receivable Follow Up
Aged OT claims are worked on a set schedule instead of left to age past timely filing.
Patient Statements and Collections
Clear, accurate patient billing for copays and coinsurance, handled with care.
Payment Posting and Reconciliation
ERA and EOB posting matched against expected reimbursement line by line.
Credentialing and Payer Enrollment
OT and OTA enrollment support, including correct taxonomy code and specialty designation on every application.
Reporting
Visibility into clean claim rate, denial trends by payer, and AR aging without having to request it.
A Credentialing Detail Many Practices Get Wrong
Getting the occupational therapy taxonomy code right at enrollment matters more than most practices realize. Occupational therapists enroll under NUCC taxonomy code 225X00000X, which crosswalks to Medicare specialty code 67. Practices with a defined clinical focus, such as driving and community mobility or gerontology, can select a more specific taxonomy subcode at enrollment instead of the general one. The wrong selection rarely causes an immediate rejection. It tends to surface later as a payer enrollment mismatch or a claim edit tied to provider type, well after the application was submitted.

What Is the Eight Minute Rule?
For timed occupational therapy codes, Medicare and many commercial payers require at least eight minutes of direct, one on one treatment time to bill a single unit. A visit with 23 to 37 minutes of documented timed treatment bills as two units. Miscounting minutes is one of the most common and most preventable sources of underbilled or denied OT claims.
What Determines an Evaluation Complexity Level?
Low complexity (97165) applies to one to two performance deficits with straightforward decision making. Moderate complexity (97166) requires three to five deficits and at least one comorbidity affecting the plan of care. High complexity (97167) applies to five or more deficits with significant comorbidities. Every level must be supported by the deficit count actually written in the note, not selected from habit.
What Goes Wrong
Where Occupational Therapy Claims Actually Break Down
These are the specific failure points we see most often when we take over billing for an OT practice, not generic denial categories.
Missing or Misplaced GO Modifier
Every Medicare Part B OT line needs it, and it is easy to drop when a practice bills PT and OT out of the same template. The result is an automatic denial that has nothing to do with whether the care was medically necessary.
Evaluation Complexity That Does Not Match the Note
Billing 97166 or 97167 when the documentation only supports one or two deficits is one of the most common findings in an OT coding review. The fix is not to under-code out of caution. It is making sure the note captures every deficit and comorbidity present.
Eight Minute Rule Miscounts
Timed units billed as flat 15 minute blocks instead of totaled and compared against the eight minute threshold either underbill a session or overstate units the documentation cannot support.
KX Threshold and Targeted Review Blind Spots
Practices that do not track cumulative OT charges per patient miss the point where the KX modifier becomes required. Claims above $2,480 without it deny outright, and claims above $3,000 can trigger a targeted review that pulls the whole chart.
NCCI Bundling on Same Day Codes
97530, 97140, and 97110 billed together on one visit without the correct override modifier get bundled by the payer’s edit logic, and one of the lines denies even when both services were genuinely provided.
OTA Service Line Errors
When an occupational therapy assistant delivers the care, or more than a minimal share of it, the CO modifier is required and payment drops to 85 percent. Skipping the modifier either loses that reduction in an audit later or denies the whole line for a missing modifier now.
Medicare Advantage Prior Authorization Denials
MA plans apply stricter and more frequent prior authorization requirements to outpatient therapy than traditional Part B, and denial rates on OT authorization requests have climbed in recent years. A plan of care approved for six visits can run out before the patient’s actual need for care does.
Recertification and Progress Note Timing
Medicare requires the plan of care to be reviewed on a defined cadence and progress documented at set treatment intervals. Missing that timing does not just risk a denial on the next claim, it gives the payer grounds to recoup claims already paid.
Our Process
How We Fix It
Eligibility, Benefit, and Threshold Check
Verify OT specific benefits, deductible status, and where the patient sits against the KX threshold before the first visit is scheduled.
Prior Authorization Tracking
Submit and track authorization requests against current payer response windows so care is not delayed waiting on an approval that is already overdue.
Complexity Matched Coding and Claim Scrubbing
Coders trained specifically in OT documentation review evaluation complexity, timed units, and modifier placement before anything is submitted.
Clean Electronic Submission
Claims go out through direct payer connections with real time rejection checks built in.
Denial Root Cause and Appeal
Every denial gets coded by reason, and clinical appeals are built around the specific criteria the payer cited, not a generic template.
AR Follow Up and Reporting
Aged claims are worked on a set schedule, with reporting that shows exactly where every dollar sits in the cycle.
Why Thrive
Why Practices Choose Thrive for Occupational Therapy Billing
Coders Trained in OT, Not Generalists
Knowing the difference between a timed treatment code and an untimed evaluation code, and coding each correctly, takes specialty specific training most general billing staff never receive.
Compliance Built Around Payer Cadence
Recertification timing, progress note intervals, and KX threshold tracking are monitored as part of the billing workflow, not left for the practice to remember on its own.
Nationwide Payer Experience
State Medicaid programs vary widely in how they cover pediatric OT. We track those differences by state instead of applying one set of rules everywhere.
Transparent Reporting
You see clean claim rate, denial reasons, and AR aging without requesting a special report.
Audit Ready Documentation Trail
Every modifier placement and complexity determination is logged, so if a payer asks for records later, the answer is already there.

Questions practice leaders ask before switching
Frequently Asked Questions
How much does occupational therapy billing cost?
Pricing is based on your visit volume, payer mix, and current claim accuracy rather than a flat rate. We provide a custom fee schedule after reviewing your practice during the free revenue review, with no separate software fee since we are a billing team, not a platform.
How long does onboarding take?
Getting started typically takes less than a week. We review your current claims, coding, and denial patterns at no cost, align our workflow to your existing EHR, and begin managing claims without disrupting how your practice already operates.
Can you take over our existing occupational therapy AR and open claims?
Yes. We review aged claims and open authorizations first, prioritize anything close to a timely filing deadline, and work the backlog alongside new claims so nothing already in progress gets dropped during the transition.
Do you bill time based codes and the eight minute rule correctly?
Yes. Every timed unit is calculated against documented minutes before submission, and evaluation codes are matched to the deficits and comorbidities actually recorded in the note rather than billed by habit.
How do you handle denied occupational therapy claims?
Every denial is coded by reason so we can see patterns by payer, not just fix one claim at a time. Appeals reference the payer's specific stated criteria, and we track appeal deadlines so a window never closes on a recoverable claim.
Is your billing team HIPAA compliant?
Yes. All claim handling, documentation review, and reporting follow HIPAA requirements, and our billers and coders are certified. Compliance is built into the workflow itself, not treated as a separate checklist.
How do we track our numbers once you take over billing?
You get regular reporting on clean claim rate, denial trends by payer, and AR aging, along with a consistent point of contact. You are not waiting on a ticket queue to find out where a claim stands.
Do you work with occupational therapy practices in every state, and do you offer consulting instead of full outsourcing?
Yes, nationwide, including state specific Medicaid programs for pediatric OT. If you are not ready for full outsourcing, we also offer billing audits and ongoing consultation for practices that want an occupational therapy billing consultant relationship first.
