Summary & Overview
HCPCS G8485: Diabetes Mellitus Measures Group
HCPCS Level II code G8485 denotes an intent to report the diabetes mellitus (DM) measures group for quality measurement and reporting purposes. Nationally, such codes matter because they enable standardized tracking of diabetes-related performance metrics across provider settings, support payer quality programs, and feed into value-based payment models. Use of G8485 signals participation in diabetes measure reporting rather than billing for a specific clinical procedure.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s purpose, the clinical and reporting context for diabetes measures, and what to expect when this code appears on claims or reporting submissions. The publication outlines typical benchmarks and policy considerations relevant to national quality programs, summarizes where this code is used in practice (ambulatory and administrative reporting settings), and identifies common follow-up items when G8485 is present on reports or claims. Data not available in the input is noted where applicable.
Billing Code Overview

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with known type 2 diabetes mellitus managed in primary care or endocrinology who is eligible for quality reporting under diabetes measures. The clinical workflow begins with a scheduled chronic care visit or telephone/telehealth encounter to assess diabetes control, review medications, obtain or review recent laboratory results (A1c, lipid panel, microalbumin), document eye and foot exams, and ensure preventive care and care coordination. During the visit the clinician documents intent to report the diabetes mellitus measures group and confirms that required data elements for measure submission are present: diagnosis of diabetes, most recent hemoglobin A1c value and date, blood pressure, LDL-c, urine albumin assessment, and care plan or counseling. Nursing or clinical staff may obtain vitals and draw labs prior to the clinician encounter. The biller assigns billing code G8485 to indicate the provider intends to report the diabetes mellitus (DM) measures group for quality reporting. Typical sites of service include outpatient primary care clinics, endocrinology clinics, community health centers, and telehealth platforms when documentation supports measure reporting. A representative patient scenario: a 58-year-old patient with long-standing type 2 diabetes presents for chronic disease management; vitals and labs are collected, A1c result is documented at 7.8% within the measurement period, LDL cholesterol is reviewed, urine albumin-to-creatinine ratio is checked, and a diabetes self-management plan is recorded. The clinic documents intention to report the diabetes measures group and appends G8485 to billing for quality reporting tracking.
