2026 Occupational Therapy CPT Codes Overview
| Item | What OT Practices Should Know |
|---|---|
| KX threshold | $2,480 for OT services |
| Targeted medical review threshold | $3,000 |
| New RTM therapy codes | 98979, 98984, 98985 |
| RTM descriptor changes | 98976 and 98977 |
| MPPR | 50% reduction to practice-expense component of applicable subsequent therapy services |
| OTA modifier | CO applies under applicable Medicare rules when the OTA exceeds the de minimis standard |
| Therapy modifier | GO identifies OT services under an OT plan of care |
AOTA specifically notes that other codes may apply depending on the patient’s condition, payer, service, and setting. Accurate medical coding services can help OT practices review CPT selection, documentation, modifiers, and payer-specific requirements before claims are submitted.
Occupational therapy billing depends on more than choosing a CPT code from a list. The code must accurately describe the skilled service provided, the documentation must support medical necessity, and the claim must follow applicable Medicare, payer, and setting-specific requirements.
For 2026, commonly used occupational therapy CPT codes include evaluation codes 97165–97167, re-evaluation 97168, therapeutic procedures such as 97110, 97112, 97140, 97530, and 97535, caregiver training codes 97550–97552, and orthotic and assistive technology codes such as 97755, 97760, 97761, and 97763. AOTA’s 2026 code list emphasizes that its list is not exhaustive and that payer acceptance and billing requirements can vary.
For Medicare in 2026, the occupational therapy KX modifier threshold is $2,480, while the targeted medical-review threshold is $3,000. CMS also added three RTM codes to its therapy code list for 2026.
What are the most common OT CPT codes for 2026?
Common occupational therapy CPT codes include 97165–97167 for evaluations, 97168 for re-evaluation, 97110 for therapeutic exercise, 97112 for neuromuscular re-education, 97140 for manual therapy, 97530 for therapeutic activities, 97535 for self-care/home management training, 97550–97552 for caregiver training, and 97760–97763 for orthotic and prosthetic management. Medicare OT billing also requires attention to timed-service rules, the $2,480 KX threshold, GO and CO modifiers, medical necessity, and applicable payer requirements.
Occupational Therapy Evaluation CPT Codes
Occupational therapy evaluation codes are selected based on the complexity of the evaluation, clinical decision-making, and documentation, not simply the patient’s diagnosis.
| CPT Code | OT Evaluation Service | Complexity | Key Documentation Focus |
|---|---|---|---|
| 97165 | OT Evaluation | Low complexity | Occupational profile, relevant history, assessment findings, clinical reasoning, and plan of care |
| 97166 | OT Evaluation | Moderate complexity | Expanded history, multiple performance deficits, assessment findings, and moderate clinical decision-making |
| 97167 | OT Evaluation | High complexity | Complex history and performance deficits, extensive assessment, and high-level clinical decision-making |
| 97168 | OT Re-Evaluation | Re-evaluation | Changes in the patient’s status, reassessment findings, updated clinical reasoning, and modifications to the plan of care |
What Are Occupational Therapy Modalities?
Modalities are physical agents used to produce therapeutic changes in biological tissue. Common examples include heat, cold, paraffin, whirlpool, electrical stimulation, diathermy, and ultrasound.
Common Supervised Modalities
| Code | Modality | Billing Type |
|---|---|---|
| 97010 | Hot or cold packs | Untimed |
| 97018 | Paraffin bath | Untimed |
| 97022 | Whirlpool | Untimed |
| 97024 | Diathermy | Untimed |
| G0281 | Electrical stimulation for qualifying chronic wounds | Untimed |
| G0283 | Unattended electrical stimulation for non-wound indications | Untimed |
| G0329 | Electromagnetic therapy for qualifying chronic wounds | Untimed |
However, supervision requirements, coverage, bundling, and separate-payment rules can vary by payer and setting.
Common Occupational Therapy Treatment CPT Codes
The following CPT codes are commonly used for occupational therapy treatment. Correct code selection should be based on the actual skilled service provided, the patient’s functional needs, documentation, and applicable payer requirements.
| CPT Code | Occupational Therapy Service | What It Covers | Key Documentation Focus |
|---|---|---|---|
| 97110 | Therapeutic Exercise | Exercises to improve strength, endurance, range of motion, and flexibility | Exercises performed, skilled techniques, functional purpose, and patient response |
| 97112 | Neuromuscular Re-Education | Movement, balance, coordination, posture, proprioception, and kinesthetic training | Impairment addressed, skilled intervention, and connection to functional goals |
| 97140 | Manual Therapy | Manual techniques such as mobilization, manipulation, manual lymphatic drainage, and manual traction | Body region, technique performed, clinical purpose, and patient response |
| 97530 | Therapeutic Activities | Dynamic, task-oriented activities designed to improve functional performance | Functional activity, skilled intervention, progression, and treatment goal |
| 97535 | Self-Care/Home Management Training | ADLs, home management, safety training, compensatory strategies, and adaptive equipment | Activity trained, patient limitations, instruction provided, and functional outcome |
| 97533 | Sensory Integrative Techniques | Techniques designed to improve sensory processing and adaptive responses | Sensory impairment, intervention, functional purpose, and patient response |
| 97537 | Community/Work Reintegration | Training related to community mobility, work tasks, shopping, transportation, and environmental needs | Functional limitation, task performed, skilled training, and reintegration goal |
| 97542 | Wheelchair Management | Wheelchair assessment, fitting, adjustment, and training | Equipment assessment, fitting or training performed, modifications, and functional need |
Caregiver Training CPT Codes
Caregiver training can be an important part of an occupational therapy plan of care, but not every caregiver interaction is separately billable. Code selection depends on the service provided, patient participation, payer rules, setting, and coverage requirements.
| CPT/HCPCS Code | Service | Time/Type | Key Billing Consideration |
|---|---|---|---|
| 97550 | Caregiver training | Initial 30 minutes | Individual caregiver training; verify payer coverage and applicable requirements |
| 97551 | Additional caregiver training | Each additional 15 minutes | Report with 97550 when additional qualifying time is provided |
| 97552 | Group caregiver training | Group service | Used when caregiver training is provided to multiple participants under applicable requirements |
| G0541–G0543 | Medicare caregiver training services | Medicare-specific | Applicable only to specified covered caregiver-training services and circumstances |
Orthotic & Assistive Technology OT Codes
Orthotic, prosthetic, physical performance, and assistive technology services are important parts of occupational therapy billing. These codes generally require documentation that supports the assessment, clinical reasoning, functional need, training, and patient response.
| CPT Code | OT Service | Billing Basis | Documentation Focus |
|---|---|---|---|
| 97750 | Physical performance testing or measurement | Each 15 minutes | Tests performed, measurements, results, and written report |
| 97755 | Assistive technology assessment | Each 15 minutes | Technology assessed, functional need, clinical reasoning, and recommendations |
| 97760 | Initial orthotic management and training | Each 15 minutes | Assessment, fitting, training, and functional purpose |
| 97761 | Initial prosthetic training | Each 15 minutes | Prosthetic training, functional goals, and patient response |
| 97763 | Subsequent orthotic/prosthetic management and training | Each 15 minutes | Adjustments, fitting, modifications, additional training, and functional need |
AOTA identifies 97750, 97755, 97760, 97761, and 97763 among the frequently used OT codes for 2026. Orthotic management codes should reflect the actual encounter and applicable payer requirements.
2026 Remote Therapeutic Monitoring (RTM) Codes for OT
Remote therapeutic monitoring (RTM) is an important 2026 development for therapy practices. CMS added 98979, 98984, and 98985 to the list of codes that sometimes describe therapy services effective January 1, 2026. CMS also revised the descriptors for 98976 and 98977.
| CPT Code | RTM Service | 2026 Reporting |
|---|---|---|
| 98975 | Initial RTM setup and patient education | Initial service |
| 98976 | Respiratory-system RTM device supply | 16–30 days |
| 98977 | Musculoskeletal RTM device supply | 16–30 days |
| 98979 | RTM treatment management | First 10 minutes |
| 98980 | RTM treatment management | Initial 20 minutes |
| 98981 | Additional RTM treatment management | Each additional 20 minutes |
| 98984 | Respiratory-system RTM device supply | 2–15 days |
| 98985 | Musculoskeletal RTM device supply | 2–15 days |
The important point is that 98979 is the new first-10-minute treatment-management code, while 98980/98981 are existing RTM management codes.
2026 Medicare KX Modifier Threshold for Occupational Therapy
The Medicare OT KX threshold is $2,480 for calendar year 2026. The threshold applies separately to OT services. CMS lists the same $2,480 amount for PT/SLP combined services, while OT has its own $2,480 threshold. The threshold increased from $2,410 in 2025 to $2,480 in 2026, an increase of $70, or approximately 2.9%. The important point is that the KX modifier does not create medical necessity. Therapy must already meet applicable coverage and medical-necessity requirements. When KX applies, the medical record should support why continued skilled OT remains reasonable and necessary.
CMS’s 2026 approved Recovery Audit Contractor topic specifically states that documentation will be reviewed for medical necessity, coding compliance and appropriate KX use.
$3,000 Targeted Medical Review Threshold
The $2,480 KX threshold should not be confused with the $3,000 targeted medical-review threshold. CMS states that the 2026 targeted medical-review threshold is $3,000 for OT and $3,000 for PT/SLP combined services. Importantly, exceeding $3,000 does not mean that every claim is automatically reviewed. The targeted review process does not subject every claim above the threshold to review.
The Medicare 8-Minute Rule for OT Billing
For Medicare timed therapy services reported in 15-minute units, total timed treatment minutes determine the number of units that may be billed.
| Total Timed Minutes | Medicare Timed Units |
| Fewer than 8 minutes | 0 units — cannot bill |
| 8 to 22 minutes | 1 unit |
| 23 to 37 minutes | 2 units |
| 38 to 52 minutes | 3 units |
| 53 to 67 minutes | 4 units |
| 68 to 82 minutes | 5 units |
| 83 to 97 minutes | 6 units |
| 98 to 112 minutes | 7 units |
| 113 to 127 minutes | 8 units |
GO and CO Modifiers for Occupational Therapy
For Medicare claims, OT practices also need to understand therapy modifiers.
GO Modifier
The GO modifier identifies services delivered under an outpatient occupational therapy plan of care.
CO Modifier
The CO modifier applies to applicable Medicare services furnished in whole or in part by an occupational therapy assistant (OTA) when CMS’s 10% de minimis standard is exceeded. Special rules apply to certain final-unit and 8-minute-rule scenarios. Practices should document the OT and OTA minutes separately and apply the CO modifier according to current CMS billing requirements.
Medicare Multiple Procedure Payment Reduction
Another reimbursement issue that deserves more attention than it receives in many OT CPT-code guides is the Multiple Procedure Payment Reduction (MPPR).
CMS states that in 2026 Medicare applies a 50% MPPR reduction to the practice-expense component of certain multiple therapy services. The highest practice-expense RVU service is paid at 100%, while the practice-expense component of subsequent applicable services is paid at 50%.
This means a practice should not assume that multiplying every billed unit by a single fee produces the final Medicare payment.
Actual reimbursement can depend on locality, place of service, payer, contractual terms and applicable payment policies.
Why Occupational Therapy Coding Accuracy Matters in 2026
The U.S. Bureau of Labor Statistics projects 14% employment growth for occupational therapists from 2024 to 2034, creating greater demand for efficient billing and documentation workflows.
As OT practices grow, higher patient volume can increase coding errors, missed treatment minutes, modifier issues, authorization problems, and claim denials. Accurate CPT coding, documentation, time tracking, and payer-specific billing checks help practices reduce denials, protect reimbursement, and maintain efficient revenue cycle management.
Common Occupational Therapy Coding Mistakes
Occupational therapy claims can be denied or underpaid when coding does not accurately reflect the service provided, treatment time, documentation, or payer requirements. Common mistakes include:
| Coding Mistake | What to Watch For |
|---|---|
| Choosing a code based on reimbursement | Select the CPT code based on the service actually provided—not the code with the highest payment. |
| Using 97530 for every functional activity | Code the service according to its clinical purpose, skilled intervention, and functional goal. |
| Missing treatment time | Accurately document minutes for timed services and ensure reported units are supported by treatment time. |
| Double-counting minutes | Do not assign the same treatment minutes to multiple timed services. |
| Using KX without support | When required, KX must be supported by documentation demonstrating continued medical necessity. |
| Ignoring OTA involvement | Review applicable Medicare CO modifier requirements when an OTA provides services. |
| Billing caregiver training without checking coverage | Verify whether the payer separately covers caregiver training and whether documentation requirements are met. |
| Applying Medicare rules to every payer | Commercial plans, Medicaid, Medicare Advantage, and other payers may have different coding, authorization, and coverage requirements. |
How to Prevent OT Billing Errors
A strong OT billing process should include eligibility and benefit verification, authorization checks, accurate CPT selection, treatment-minute validation, modifier review, documentation audits, and payer-specific claim edits.
Practices should also monitor denials and underpayments by CPT code, payer, therapist, and location. Regular audits of high-volume OT codes can identify recurring coding problems before they affect a larger number of claims.
Conclusion
Accurate occupational therapy billing requires more than selecting the right CPT code. Proper coding, documentation review, timed-unit calculation, modifier application, and payer-specific compliance all play a role in clean claims and timely reimbursement.
Because Medicare and payer requirements can change, OT practices benefit from experienced medical coding services that help maintain coding accuracy, reduce avoidable denials, and support compliant billing workflows.
