Summary & Overview
HCPCS G8667: Residual Score for Elbow, Wrist or Hand Impairment
HCPCS Level II code G8667 documents a calculated residual score for elbow, wrist, or hand impairment with a reported value of zero or greater. This code captures standardized functional assessment results that inform care planning, functional status tracking, and administrative reporting across outpatient and therapy settings. Nationally, consistent use of impairment scoring codes supports continuity of care, quality measurement, and appropriate claims adjudication for musculoskeletal and rehabilitative services. Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise explanation of the code’s clinical meaning and service setting, guidance on common billing contexts, and an overview of what data and documentation are relevant when reporting this code. The publication also highlights typical modifiers seen in billing practice and notes where input data are not available. This summary is intended for health policy analysts, coders, payers, and clinical administrators seeking a national perspective on reporting and administrative use of impairment scoring for the upper extremity.
Billing Code Overview
HCPCS Level II code G8667 indicates that a residual score for the elbow, wrist, or hand impairment has been successfully calculated and that the resulting score was equal to zero (0) or greater than zero (> 0). This code documents the presence and quantification of residual functional impairment for the upper extremity after treatment or evaluation.
-
Service type: Impairment scoring/functional assessment
-
Typical site of service: Outpatient clinic or therapy setting where standardized impairment scoring of the elbow, wrist, or hand is performed
Clinical & Coding Specifications
Clinical Context
A 48-year-old right-handed carpenter presents to an outpatient occupational medicine clinic eight weeks after an open reduction and internal fixation (ORIF) of a distal radius fracture and repair of an ulnar-sided laceration. The treating hand surgeon performs a standardized impairment evaluation of the elbow, wrist, and hand to calculate a residual impairment score using range of motion, grip strength, sensory testing, and functional limitation assessment. The evaluator documents that the residual score was successfully calculated and the final numeric score was 0 (no residual impairment) despite previously recorded deficits during early post-op visits. The clinical workflow includes review of operative reports and therapy notes, objective measurements (goniometry, dynamometry, Semmes-Weinstein), calculation using the accepted impairment rating methodology, documentation of the result in the medical record, and submission of the HCPCS Level II code G8667 to report that a residual score for elbow, wrist, or hand impairment was calculated and the score equaled zero or greater than zero.
