Summary & Overview
CPT 95851: Range of Motion Measurement and Report for Extremities or Spine
CPT code 95851 represents formal range of motion measurements and reporting for each extremity (excluding the hand) or each trunk section (spine). This code is integral to physical and occupational therapy, providing objective data on joint mobility and functional status. Nationally, the code is recognized by major payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare, ensuring broad coverage for therapy services across diverse patient populations.
This publication offers a comprehensive overview of 95851, detailing its clinical context, typical sites of service, and its role in therapy evaluations. Readers will gain insight into payer coverage, relevant policy updates, and benchmarks for utilization. The code is commonly used in outpatient therapy clinics, supporting the assessment and documentation necessary for effective rehabilitation and care planning. Understanding the scope and application of 95851 is essential for professionals involved in therapy services, billing, and healthcare policy.
Key topics include payer coverage, clinical indications, and the relationship of 95851 to other therapy evaluation codes. The summary also highlights the importance of accurate range of motion measurement in patient care and reimbursement processes.
CPT Code Overview
CPT code 95851 is used to report formal range of motion measurements and documentation for each extremity (excluding the hand) or each trunk section (spine). This procedure is typically performed as part of physical or occupational therapy services to assess joint mobility and functional status. The service is most commonly provided in therapy service settings, such as outpatient physical or occupational therapy clinics. Accurate measurement and reporting of range of motion are essential for evaluating patient progress and guiding treatment plans.
Clinical & Coding Specifications
Clinical Context
A patient presents to an outpatient physical therapy clinic with complaints of pain and limited mobility in the right knee following a recent injury. The physical therapist conducts a formal range of motion measurement for the right lower extremity, documenting the degree of movement and any restrictions. This assessment is performed as a separate procedure to objectively quantify functional limitations and guide the development of a rehabilitation plan. The results are reported in the patient's medical record and may be repeated during subsequent visits to monitor progress.
