Summary & Overview
HCPCS G8502: Completion of Back Pain Quality Measures
HCPCS Level II code G8502 documents that all required quality actions within a back pain measures group have been completed for a patient. As a quality-reporting marker, it signals adherence to a predefined set of clinical and documentation steps related to back pain care. Nationally, such codes support performance measurement, care coordination, and value-based reporting across payers and health systems.
Key payers included in this discussion are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The code is relevant to outpatient and ambulatory care settings where clinicians assess, treat, and document back pain quality measures.
Readers will find a concise explanation of what G8502 represents, the typical clinical context and site of service, and what to expect in benchmarking and policy discussions: how the code functions as a quality-completion indicator, implications for quality reporting workflows, and common intersections with quality programs and payer reporting requirements. Data not available in the input will be clearly noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 45-year-old patient presents to a primary care clinic with a 6-week history of non-radicular low back pain after a minor lifting injury. The clinician performs a standardized back pain quality assessment and documents education, functional assessment, pain scoring, shared decision-making, activity recommendations, and follow-up planning consistent with the back pain measures group. The clinical workflow includes initial history and exam, use of validated screening tools (e.g., pain and function scales), conservative therapy counseling (activity modification, physical therapy referral), documentation of opioid risk assessment and avoidance of imaging when not indicated, and arranging timely follow-up. After completing all required quality actions for each applicable measure in the back pain measures group, the clinician documents completion and the visit is coded using G8502 to indicate all quality actions for the applicable measures were performed for this patient.
