Summary & Overview
HCPCS G9737: Elbow/Wrist/Hand FS PROM Unable to Complete
HCPCS Level II code G9737 documents that a patient could not complete the elbow/wrist/hand functional status passive range of motion (fs PROM) assessment at initial evaluation and/or discharge due to barriers such as blindness, illiteracy, severe mental incapacity, or language incompatibility, with no adequate proxy available. Nationally, this code matters because it standardizes reporting when routine functional assessments cannot be completed for legitimate patient-centered reasons, supporting accurate quality measurement and claims documentation. Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn the clinical context for use of G9737, the typical service setting (outpatient therapy or home health/clinic-based rehabilitation), how the code fits into functional status assessment workflows, and what benchmarks and policy topics to consider when this code is used in reporting. The publication highlights documentation elements tied to the code’s intent, implications for functional outcome datasets, and common billing considerations where available.

Billing Code Overview
HCPCS Level II code G9737 indicates that a patient was unable to complete the elbow/wrist/hand functional status passive range of motion (fs PROM) assessment at initial evaluation and/or discharge because of blindness, illiteracy, severe mental incapacity, or language incompatibility, and an adequate proxy was not available to assist. The service type is functional status assessment (elbow/wrist/hand passive range of motion) performed as part of a therapy evaluation or discharge assessment. The typical site of service is an outpatient therapy or rehabilitation setting, including home health or clinic-based therapy encounters where fs PROM would normally be documented.

Clinical & Coding Specifications
Clinical Context
A 72-year-old patient with recent right distal radius fracture is referred for outpatient physical therapy for elbow/wrist/hand functional status (FS) passive range of motion (PROM) assessment at initial evaluation and planned discharge. At initial evaluation the patient is profoundly blind and has severe cognitive impairment from advanced dementia; no family or legally authorized representative is present or available to provide informed assistance or to perform proxy-directed measurements. The therapist documents inability to complete standardized elbow/wrist/hand FS PROM measurement due to visual impairment and severe mental incapacity and records attempts to secure a proxy.
The clinical workflow: the therapist attempts standardized PROM testing during the initial evaluation, documents the barrier (blindness, illiteracy, severe mental incapacity or language incompatibility) and the absence of an adequate proxy, and bills the service-level HCPCS Level II code G9737. If circumstances later permit PROM assessment (proxy becomes available or patient's status improves), the therapist performs and documents the measurement at discharge or a subsequent visit and bills the appropriate CPT/HCPCS codes at that time. Notes include attempts to contact proxies, time-stamped documentation of the barrier, and clinical rationale for why standardized PROM could not be completed.
