Comprehensive Guide to Occupational Therapy CPT Codes

Occupational therapy is a vital healthcare service that assists individuals in regaining or enhancing their ability to perform daily activities and improve their overall quality of life. For occupational therapists and medical billers, understanding the complex world of Occupational Therapy CPT Codes is essential to ensure accurate documentation and proper reimbursement for services provided. In this extensive guide, we will explore every facet of Occupational Therapy CPT Codes, including available codes, methods, requirements, and the latest updates in this field.

Occupational Therapy Billing & Coding

Occupational Therapy CPT Codes play a pivotal role in the healthcare system, enabling occupational therapists to provide effective treatment and ensure that patients receive the care they need. Here, we provide a comprehensive overview, including the latest developments.

The Designation of Time in Billing

Before we delve into the list of Occupational Therapy CPT Codes, it’s crucial to understand how time is designated within these codes. Occupational therapy services are typically measured and billed based on the amount of time spent with a patient. The standard unit of time used for billing purposes is 15 minutes. For example, if an occupational therapist spends 45 minutes on a particular service, you would bill for three units of the respective CPT code.

CPT Codes for Occupational Therapy

Occupational Therapy CPT Codes encompass a wide range of services, including evaluations, therapeutic interventions, modalities and procedures, orthotic and prosthetic management, and more. Below is a list of these codes, categorized for clarity:

Evaluation and Re-Evaluation Codes


Low Complexity Evaluation

Occupational therapy evaluation, low complexity: This code is used for straightforward initial evaluations, typically involving a single area of occupational therapy focus.


Moderate Complexity Evaluation

Occupational therapy evaluation, moderate complexity: Moderate complexity evaluations are coded using this number and involve assessments of multiple factors or areas of concern.


High Complexity Evaluation

Occupational therapy evaluation, high complexity: High complexity evaluations require a comprehensive assessment of multiple factors, potentially involving multiple therapists or disciplines.



Occupational therapy re-evaluation: Use this code for re-evaluations conducted to assess progress and make changes to the treatment plan.
