Common CPT Codes for Occupational Therapy

Last Updated on July 28, 2026

Accurate Occupational Therapy CPT Codes are essential for reporting therapy services, supporting compliant billing, and receiving appropriate reimbursement. These standardized procedure codes identify the evaluations, therapeutic interventions, and functional training provided during occupational therapy while helping Medicare, Medicaid, and commercial payers determine payment.

As coding and payer requirements continue to evolve, selecting the appropriate CPT code requires accurate clinical documentation, proper reporting of treatment time, and compliance with payer-specific billing requirements. These elements work together to support accurate reimbursement and reduce avoidable billing errors.

Understanding the most commonly reported Occupational Therapy CPT Codes helps therapists and billing teams improve coding accuracy, reduce billing errors, and maintain consistent reimbursement.

Understanding Occupational Therapy Treatment Categories

Occupational therapy services are reported using different CPT code categories based on the type of treatment provided rather than the patient’s diagnosis. Some codes are used for initial evaluations, while others report therapeutic exercises, neuromuscular reeducation, manual therapy, self-care training, community reintegration, and performance testing. 

Understanding these treatment categories makes selecting the appropriate Occupational Therapy CPT Code much easier. Organizing services by category helps therapists and billing teams improve documentation, report services more accurately, and maintain greater consistency throughout the billing process. 

Occupational Therapy Evaluation CPT Codes

These codes are used to report the initial assessment of a patient’s functional abilities, performance limitations, and rehabilitation needs. Selecting the appropriate evaluation code depends on the complexity of the patient’s condition, the number of performance deficits identified, and the level of clinical decision-making required. These evaluations establish the baseline for treatment planning and guide the development of individualized therapy goals. 

• 97165 – Low Complexity Evaluation 

Designed for patients with limited performance deficits requiring straightforward clinical decision-making. 

• 97166 – Moderate Complexity Evaluation 

Appropriate when multiple performance deficits require a broader clinical assessment and moderate clinical decision-making.  

• 97167 – High Complexity Evaluation 

Reported for comprehensive assessments involving significant impairments, multiple comorbidities, and complex treatment planning. . 

• 97168 – Occupational Therapy Re-evaluation 

Performed when a patient’s condition or treatment goals change enough to require a formal reassessment of the existing plan of care. . 

Therapeutic Exercise and Activity CPT Codes

These CPT codes represent some of the most frequently reported Occupational Therapy CPT Codes because they focus on improving a patient’s physical function and ability to perform everyday activities. While both categories support rehabilitation, therapeutic exercises target physical impairments, whereas therapeutic activities emphasize real-world functional movement and task performance.

97551	Additional Caregiver Training (15 Minutes)	Used for each additional 15 minutes of caregiver instruction beyond the initial session.
97552	Group Caregiver Training	Covers caregiver education delivered in a group setting and reported as an untimed service.

Occupational Therapy Billing Guidelines

Accurate coding alone does not guarantee successful reimbursement. Effective occupational therapy billing also depends on correct unit reporting, complete documentation, appropriate modifier usage, and adherence to payer-specific billing requirements. Following standardized billing practices helps reduce preventable denials, improve claim quality, and support consistent reimbursement across occupational therapy services.

Timed vs. Untimed Occupational Therapy CPT Codes

One of the most important billing concepts is understanding whether a CPT code is timed or untimed. Timed services are billed based on the total minutes of direct one-on-one patient treatment, while untimed services are generally reported once per treatment session regardless of the treatment duration.

Timed CPT Codes

These services are billed according to the total treatment time documented during the patient encounter.

• 97110 – Therapeutic Exercise
• 97112 – Neuromuscular Reeducation
• 97124 – Therapeutic Massage
• 97140 – Manual Therapy
• 97530 – Therapeutic Activities
• 97533 – Sensory Integrative Techniques
• 97535 – Self-Care/Home Management Training
• 97537 – Community and Work Reintegration
• 97542 – Wheelchair Management and Training
• 97760 – Orthotic Management and Training

Untimed CPT Codes

These codes are typically reported once per visit, regardless of the total time spent delivering the service.

• 97165–97168 – Occupational Therapy Evaluation and Re-evaluation
• 97010 – Hot or Cold Packs
• 97552 – Group Caregiver Training

Understanding the 8-Minute Rule

Most Medicare and many commercial insurance plans use the 8-Minute Rule to determine the number of billable units for time-based occupational therapy services. The total minutes of direct one-on-one treatment determine how many units can be reported on the claim.

Direct Treatment Time	Billable Units
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

Accurate time tracking is essential because incorrect unit reporting is one of the most common occupational therapy billing errors.

Documentation, Common ICD-10 Codes, and Modifier Usage

Complete documentation supports accurate coding and demonstrates the medical necessity of every occupational therapy service billed. Well-documented treatment records also improve claim quality and help practices prepare for payer reviews and audits.

Documentation Checklist

Every occupational therapy treatment note should include:

✔ Patient diagnosis and functional limitations

✔ Initial evaluation findings or progress assessment

✔ Measurable treatment goals

✔ Skilled interventions performed

✔ Total treatment time for timed services

✔ Patient response to treatment

✔ Progress toward established goals

✔ Updated plan of care when clinically appropriate

Strong documentation establishes a clear connection between the reported CPT code, the diagnosis, and the skilled services delivered.

ICD-10 Codes Associated with Occupational Therapy

The diagnosis code reported on the claim should accurately reflect the patient’s documented condition and support the medical necessity of the occupational therapy services performed.

ICD-10 Code	Common Diagnosis
M62.81	Muscle weakness (Generalized)
M25.511	Pain in right shoulder
M54.50	Low back pain
R26.89	Other abnormalities of gait and mobility
G81.90	Hemiplegia, unspecified
I69.398	Sequelae of cerebrovascular disease
F82	Developmental disorder of motor function
S72.001A	Fracture of neck of femur (Initial encounter)

The ICD-10 diagnosis reported should accurately reflect the patient’s documented condition while establishing the medical necessity for the occupational therapy services billed.  

Modifiers Used in Occupational Therapy CPT Codes

Modifier selection varies by payer and service type. Applying the correct modifier helps clarify how occupational therapy services were delivered and supports accurate claim processing.

• Modifier GO – Indicates services were provided under an occupational therapy plan of care. 
• Modifier CO – Identifies outpatient occupational therapy services furnished in whole or in part by an Occupational Therapy Assistant (OTA), in accordance with CMS requirements. 
• Modifier 59 – Distinguishes a separate and independently identifiable service performed during the same treatment session. 
• Modifier TF – Identifies services performed by a Certified Occupational Therapy Assistant (COTA) under general supervision when required by specific payers. 
• Modifier TL – Reports Birth-to-Three services delivered in the patient’s natural environment when required by payer guidelines.
• Modifier GT – Indicates occupational therapy services delivered through telehealth using interactive audio and video technology. 
• Modifier 95 –  Reports synchronous telehealth services provided through real-time audio and video communication. 

Common Occupational Therapy Coding Mistakes That Affect Reimbursement 

Many reimbursement delays occur because of preventable coding and documentation errors rather than incorrect clinical care. Regular coding reviews and standardized billing workflows help reduce these issues before claims are submitted.

Common mistakes include:

• Selecting an evaluation code that does not match the documented level of complexity.
• Reporting incorrect treatment units for timed CPT codes.
• Omitting payer-required modifiers.
• Incomplete documentation supporting medical necessity.
• Linking CPT codes with inappropriate or unspecified ICD-10 diagnosis codes.
• Failing to update the plan of care when the patient’s condition changes.
• Missing prior authorization or payer-specific documentation requirements.
• Submitting claims without verifying payer-specific occupational therapy billing policies.

Implementing consistent documentation standards, coding reviews, and staff education helps improve claim quality while reducing avoidable denials and reimbursement delays.
