Summary & Overview
HCPCS G8499: Rheumatoid Arthritis Quality Measures Completed
HCPCS Level II code G8499 denotes that all specified quality actions for the rheumatoid arthritis (RA) measures group have been completed for a patient. Nationally, this code supports quality reporting and compliance efforts tied to RA care pathways, performance measurement, and value-based payment programs. Accurate use of G8499 facilitates documentation that quality measures — such as medication management, disease activity assessment, and patient education components included in RA measure sets — were performed.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. These payers participate in various quality-reporting and value-based arrangements where documentation of completed measure sets affects quality scores and potential incentives.
Readers will learn what HCPCS Level II code G8499 represents, the typical service setting and clinical context, and how the code functions within national quality reporting frameworks. The publication provides benchmarks and policy context relevant to quality measurement for rheumatoid arthritis, notes on billing and documentation practice considerations, and connections to related quality measure reporting. Data not available in the input is identified explicitly where applicable.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with established rheumatoid arthritis (RA) managed in ambulatory rheumatology care. The patient presents for a regular disease management visit during which the clinician documents disease activity, functional status, medication reconciliation (including disease-modifying antirheumatic drugs and biologics), safety monitoring (laboratory tests such as CBC, liver function tests, and hepatic/renal panels), and vaccination or screening updates as required by RA quality measures. The clinical workflow includes pre-visit planning (review of prior labs and medication adherence), point-of-care disease activity assessment (for example with CDAI or RAPID3), ordering or review of required labs, documentation of shared decision-making about treatment, and completion of all measure-specific electronic health record fields. Billing uses HCPCS code G8499 to indicate that all quality actions for the RA measures group applicable to this patient during the measurement period have been performed and documented.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure or other service | Use when a distinct E/M visit is provided the same day as quality-related procedures or lab draws and is documented separately. |
