HCPCS Level II code G0151 identifies physical therapy services delivered by a qualified physical therapist in a home health or hospice setting and billed in 15-minute units. This code is important for accurately capturing home-based rehabilitative care intensity, supporting care coordination for patients who cannot access outpatient clinics, and informing national utilization and payment policy for home health therapy services.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of fee and billing practices for home-based physical therapy, common clinical contexts where G0151 is used, and comparisons to related home therapy codes such as S9131. The publication provides benchmarks on unitization and common diagnosis pairings for home therapy, summarizes relevant billing considerations, and outlines the clinical scenarios—such as muscle weakness, gait difficulty, and localized joint pain—where home physical therapy is typically applied.

This national-level summary is intended to help billing professionals, rehabilitation program managers, and policy analysts understand how G0151 is applied across major payers, what clinical settings drive use of the code, and which operational factors influence its documentation and reporting.
