Occupational Therapy Billing Codes and Reimbursement Rates: A Complete 2026 Guide

This 2026 guide strips away the jargon, walks through the CPT codes OT practitioners actually use, explains what Medicare and commercial payers are currently reimbursing, and offers real-world guidance on documentation practices that support clean claims from day one.

Why OT Billing Has Gotten More Complex Not Less

The landscape of occupational therapy reimbursement has shifted considerably over the past few years. Medicare’s ongoing transition toward value-based payment models, the expansion of telehealth CPT codes post-pandemic, and payer-specific policy updates have collectively made billing a moving target. In 2026, practitioners also contend with stricter medical necessity documentation standards, quarterly LCD (Local Coverage Determination) reviews, and increased audit scrutiny from both Medicare Administrative Contractors (MACs) and commercial insurers.

The good news? Practitioners who understand the architecture of OT billing how codes are structured, how time is counted, how modifiers function are better positioned to navigate policy changes without scrambling every quarter.

Understanding the CPT Code Framework for Occupational Therapy

Current Procedural Terminology (CPT) codes are the universal language between providers and payers. For occupational therapists, the relevant codes fall primarily within a few clusters:

Evaluation Codes (97165–97167) Therapeutic Procedure Codes (97110, 97112, 97129, 97150, etc.) Specialty-Specific Codes (97003, 97004, cognitive rehabilitation, ADL training) Telehealth and Remote Therapeutic Monitoring Codes (98975–98984)

Each cluster carries its own documentation requirements, time thresholds, and reimbursement logic. Let’s dig in.

Occupational Therapy Evaluation and Re-Evaluation Codes

97165 — OT Evaluation, Low Complexity

This code applies when the presenting clinical problem involves a limited number of performance areas, the occupational profile is straightforward to construct, and the analysis of occupational performance is uncomplicated. Think of a patient recovering from a distal radius fracture who needs a functional assessment before starting hand therapy.

2026 Medicare National Rate (non-facility): approximately $86 $102 depending on geographic locality.

Documentation must include: an occupational profile, an analysis of occupational performance, and a plan of care outlining frequency, duration, and measurable goals.

97166 — OT Evaluation, Moderate Complexity

This is the workhorse evaluation code for most OT settings. It applies when there are multiple performance areas or contexts involved, when clinical decision-making requires weighing comorbidities, or when the activity demands analysis is more nuanced. A stroke patient presenting with both upper extremity deficits and cognitive-perceptual challenges often warrants this level.

2026 Medicare National Rate (non-facility): approximately $120–$140.

97167 — OT Evaluation, High Complexity

Reserved for patients with severe impairments across multiple performance areas for instance, someone with a traumatic brain injury presenting with motor, cognitive, visual-perceptual, and psychosocial deficits simultaneously. The occupational profile must be highly detailed, and the clinical reasoning documented must reflect the multidimensional nature of the presentation.

2026 Medicare National Rate (non-facility): approximately $162–$178.

97168 — OT Re-Evaluation

Used when a patient’s clinical status changes significantly enough to warrant a fresh evaluation, or when the plan of care needs a major revision. It cannot be billed on the same day as an evaluation, and most payers require documentation that justifies why a re-evaluation is clinically necessary rather than simply progress-note-level reassessment.

2026 Medicare National Rate (non-facility): approximately $72–$90.

Therapeutic Procedure Codes: Time-Based Billing in Practice

Here is where many OT practitioners especially newer graduates trip up. The majority of therapeutic procedure codes are time-based, meaning the number of units billed depends directly on the face-to-face treatment time spent with the patient. The standard unit increment is 15 minutes, and CMS uses the “8-minute rule” to determine how many units can be billed in a given session.

The 8-Minute Rule, Explained Simply

If you spend at least 8 minutes providing a single timed service, you can bill one unit. Here is how it scales:

Time Spent	Units Billable
8–22 minutes	1 unit
23–37 minutes	2 units
38–52 minutes	3 units
53–67 minutes	4 units
68–82 minutes	5 units

When multiple timed codes are provided in one session, the units are calculated based on total timed minutes, then allocated across the codes. This is where documentation precision becomes non-negotiable — your notes must support the time you report.

97110 Therapeutic Exercises

Despite being a physical therapy staple, 97110 is absolutely within OT scope of practice when the therapeutic exercise directly addresses occupational performance. Strengthening exercises for a patient with rotator cuff pathology who wants to return to cooking, or range-of-motion activities for someone rebuilding hand function these are legitimate 97110 territory for OT.

• 2026 Medicare National Rate (non-facility): approximately $33 $39 per unit.
• Billing tip: Always link the exercise to a specific occupational goal in your documentation. “Patient performed shoulder flexion strengthening to improve ability to reach overhead cabinets during meal preparation” is far stronger than “performed shoulder flexion exercises.”

97112 Neuromuscular Reeducation

This code is frequently misunderstood. It is appropriate when the clinical goal involves improving movement, balance, coordination, or proprioception through neuromuscular retraining techniques.

• 2026 Medicare National Rate (non-facility): approximately $34 $41 per unit.
• Common documentation pitfall: 97112 must reflect activities that specifically challenge neuromuscular control, not simply exercise. Facilitating proper movement patterns during functional tasks, balance challenges during standing ADLs, or proprioceptive work with unstable surfaces all fit. Passive stretching does not.

97129 & 97130 Therapeutic Interventions for Cognitive Function

These codes were a significant addition to OT billing and remain among the most relevant for practitioners working in cognitive rehabilitation, mental health, and brain injury settings.

• 97129 covers the first 15 minutes of therapeutic interventions focused on cognitive function, including attention, memory, problem-solving, and executive functioning.
• 97130 is the add-on code for each additional 15-minute increment.
• 2026 Medicare National Rate (non-facility): 97129 approximately $42–$52, 97130 approximately $39–$46.
• Who can bill: Occupational therapists and speech-language pathologists. Documentation must reflect occupational performance focus for OT.

97150 Therapeutic Procedures, Group

When two or more patients receive treatment simultaneously, 97150 applies in place of individual procedure codes.

• 2026 Medicare National Rate (non-facility): approximately $19–$23 per patient.
• Common uses: social skills groups, upper extremity rehab groups, ADL training groups.
• Medicare requirement: group size, therapist involvement, and clinical appropriateness must be clearly documented.

97535 Self-Care/Home Management Training

This is one of the most distinctly occupational therapy codes in the entire CPT system. It covers direct one-on-one training in activities of daily living dressing, bathing, grooming, meal preparation, home management tasks, and compensatory strategies using adaptive equipment.

• 2026 Medicare National Rate (non-facility): approximately $36–$44 per unit.
• Documentation gold standard: specify task trained, adaptive equipment used, patient response, and measurable progress toward goals.
• Example: “Patient practiced one-handed shirt donning using a dressing hook; achieved independent donning in 4 minutes with 1 verbal cue, compared to 7 minutes last session.”

Telehealth and Remote Therapeutic Monitoring The 2026 Landscape

Telehealth CPT codes have matured considerably since their emergency-era expansion. In 2026, CMS has maintained permanent coverage for select OT services delivered via audio-video technology, though the approved service list and modifier requirements vary by MAC jurisdiction.

Relevant codes for OT telehealth:

• 97165–97168 (evaluations via telehealth, with modifier 95 or GT depending on payer)
• 98975–98977 Remote therapeutic monitoring setup and device supply codes
• 98980–98981 RTM treatment management codes (20+ minutes of clinical staff time per calendar month)

Remote therapeutic monitoring represents a genuine revenue opportunity for outpatient OT practices, particularly those serving patients with chronic conditions, home health transitions, or geographic barriers. However, the documentation requirements are layered — clinicians must track device-generated data, clinical response time, and patient communication within specific billing windows.

Medicare Therapy Thresholds and KX Modifier in 2026

The Medicare therapy cap, formally replaced by the KX modifier threshold system, requires that once a patient’s combined physical therapy and occupational therapy expenditures exceed the annual threshold, the treating therapist must attest via the KX modifier that services remain medically necessary and are consistent with clinical standards.

2026 OT Therapy Threshold: approximately $2,330 (confirmed annually by CMS; verify with your MAC for final figures).

Beyond a secondary threshold, claims may face targeted review. This does not mean you cannot continue treating it means your documentation must be airtight. Functional outcome measures, standardized assessments, and clearly articulated goals become your shield during audit season.

Modifier Usage: Getting It Right the First Time

Modifiers clarify billing circumstances without changing the fundamental nature of the service. The most relevant modifiers for OT billing in 2026 include:

GP Services delivered under an outpatient physical therapy or occupational therapy plan of care. Required on all OT claims billed to Medicare.

59 Distinct procedural service. Used when two codes that might otherwise appear bundled are legitimately separate and distinct. Requires solid documentation to withstand audit.

95 Synchronous telemedicine service rendered via real-time interactive audio and video.

KX Attestation that services are medically necessary and that records support continued treatment beyond the therapy threshold.

CO Services furnished by an occupational therapist assistant under the supervision of an occupational therapist. CMS requires this modifier on claims for OTA-provided services.

The CO modifier and the associated 85% payment reduction applied to OTA services since 2022 remains a significant financial consideration for practices with OTA staff. Understanding how to structure care delivery to optimize clinical value while managing reimbursement impact is a strategic conversation every OT practice owner should be having regularly.

Commercial Payer Reimbursement What to Expect in 2026

Medicare rates serve as a benchmark, but commercial payer reimbursement varies substantially from near-Medicare levels for some regional carriers to 130 -160% of Medicare for well-negotiated contracts with major insurers. A few patterns worth noting in 2026:

High-value codes for commercial billing: Cognitive rehabilitation codes (97129/97130) tend to see favorable reimbursement from commercial payers, particularly for acquired brain injury populations. Driver rehabilitation evaluations, lymphedema management, and low vision rehabilitation often carry premium rates under specialty endorsements.

Prior authorization trends: Many commercial payers have expanded PA requirements for outpatient OT, particularly beyond the initial evaluation. Investing in a streamlined PA workflow with templated clinical summaries that front-load functional outcome data can meaningfully reduce claim holds and administrative burden.

Coordination of benefits: For patients with Medicare as primary and a Medigap or Advantage plan as secondary, always verify whether the secondary plan follows Medicare’s approved amount or applies a separate fee schedule. This distinction can meaningfully affect patient cost-sharing and your collections.

Documentation Practices That Protect Your Revenue

Revenue cycle integrity in OT ultimately lives or dies in the clinical note. Here are the documentation principles that matter most in 2026:

Functional language is non-negotiable. Every goal, every intervention description, and every progress note should speak to the patient’s ability to perform meaningful occupations. Payers are not funding exercises they are funding functional restoration.

Quantify everything you can degrees of motion, number of verbal cues, time to complete a task, FIM scores, DASH scores, MMSE scores objective data transforms a defensible note into an auditor-proof one.

Link the dots explicitly never assume a reviewer will connect the clinical intervention to the occupational goal. Write that connection out, every time.

Maintain start and stop times for timed codes this is a basic requirement that is frequently missing in audit-flagged claims.

Re-certification timing for Medicare plans of care must be certified by a physician or NPP, and recertification must occur at least every 90 days. Missing this window creates a coverage gap that payers will exploit during post-payment review.

Looking Ahead: What OT Practitioners Should Watch in Late 2026

CMS has signaled continued movement toward outcome-based payment models, and the American Occupational Therapy Association (AOTA) is actively engaged in policy advocacy to ensure OT’s place in evolving payment structures. Practitioners who track the annual Physician Fee Schedule proposed rule (released each July) and who engage with AOTA’s regulatory updates will be far ahead of colleagues who wait for changes to arrive at their front desk.

Additionally, the expansion of OT services in school settings, telehealth, and home and community-based care is gradually being reflected in updated coverage policies. Staying connected to your MAC’s LCD updates and AOTA’s practice guidelines will keep your billing current.
