HCPCS code G0109: Diabetes training, group session2026 Medicare rate & RVUs

Medicare pays $16.03 for G0109 nationally in the office. Local office rates run $14.83–$20.54.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What G0109 covers

G0109 represents diabetes self-management training delivered to a group of at least two patients, in 30-minute units. The session may cover practical skills such as glucose monitoring, medication use, food choices, physical activity, and recognizing or responding to glucose problems. Registered nurses, dietitians, pharmacists, and other qualified diabetes educators commonly provide this training through an organized outpatient program in a clinic or community setting.

Report the code for the group-training service, not for one-to-one education; individual diabetes training is reported with G0108. The record should support the training date and time, group format, attendance, instructor, topics covered, and each patient’s participation or learning needs. CMS fee-schedule payment is tied to the reported 30-minute units. Keep documentation distinct when a patient also receives medical nutrition therapy, since that service has a different focus and code set.

How the G0109 rate is calculated

Each of G0109’s three RVUs is multiplied by a geographic index (GPCI) for the payment locality, added up, and multiplied by the conversion factor. Drag the indexes or enter a ZIP to see what moves the rate.

Payment rules and modifiers for G0109

G0109 has no global surgery period, no multiple-procedure, bilateral or assistant-at-surgery adjustment, and no professional/technical split. What changes the payment is where the service happens: the place of service on the claim decides whether Medicare pays the office or the facility rate.
