Summary & Overview
HCPCS G8652: Hip Impairment Residual Score < 0
HCPCS Level II code G8652 denotes that a residual score for hip impairment was calculated and found to be less than zero. The code is used to document a specific assessment outcome for hip function or impairment scoring; it matters nationally as a standardized way to record negative residual scores in medical records and claims, supporting clinical documentation and performance measurement. Key payers commonly relevant to coverage and claims processing include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise explanation of what the code represents and the clinical context for its use, an outline of typical sites of service and service type, and information on common modifiers and payer considerations where available. The publication summarizes benchmarks and reporting practices relevant to impairment scoring, highlights policy or billing guidance when available, and provides clinical context for how a negative residual hip score is recorded. Data not available in the input is noted as such in relevant sections.
Billing Code Overview
HCPCS Level II code G8652 indicates that a residual score for the hip impairment was successfully calculated and the score was less than zero (< 0). This code documents the outcome of an assessment that produced a negative residual score for hip impairment, reflecting the measured status as defined by the reporting instrument.
-
Service type: Functional assessment/impairment scoring for the hip
-
Typical site of service: Outpatient clinic or rehabilitation setting where hip impairment assessments are performed
Clinical & Coding Specifications
Clinical Context
A 68-year-old male with a history of left total hip arthroplasty presents for a post-operative functional assessment. The orthopedist documents persistent mild limp and reported instability but objective testing indicates no positive impairment when applying the standardized hip residual scoring algorithm used for impairment evaluations. The clinician completes the impairment calculation and the derived residual score is less than zero, indicating no measurable residual impairment attributable to the hip. The service is typically performed in an outpatient orthopedic clinic, specialty rehabilitation clinic, or an independent medical evaluation setting. The workflow includes: initial history and focused musculoskeletal exam, review of imaging and operative reports, application of a validated hip impairment scoring method, calculation of the residual score, documentation of findings and calculation result, and generation of an impairment statement or return-to-work documentation as required by the referring source or payer.

| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when documentation supports substantially greater work than typical for an impairment assessment due to complexity of documentation or unusual factors |
