G0108 with Medicare: what the policy says
The short answerThis is Medicare's diabetes self-management training (DSMT) code, a separate benefit from MNT. A patient can get both, but never G0108 and 97802/97803/97804 on the same date of service.

What Medicare's policy says about G0108
G0108 is the HCPCS code for diabetes outpatient self-management training services, individual, per 30 minutes. At Medicare it is limited: paid only in a narrow case, see the note. Each line below is from Medicare's own text:
- Where it is listed. Named in Claims Processing Manual ch. 18 s.120.1 as the DSMT code (individual, per 30 minutes). DSMT is a separate benefit from MNT. (CMS, checked October 30, 2026; CMS, checked October 30, 2026)
- When it pays. DSMT and MNT can be given in the same time period with the full hours of each (10 hours initial DSMT plus 3 hours MNT), but not on the same date of service for the same beneficiary. A claims edit checks for duplicate dates. (CMS, checked October 30, 2026; CMS, checked October 30, 2026)
- Diagnosis position. Type of service 1. Physician claims go to the A/B MAC (B) and are paid under the physician fee schedule. (CMS, checked October 30, 2026)
- What the member pays. Deductible and coinsurance apply to DSMT under ch. 18 s.120.1. (CMS, checked October 30, 2026)
- Telehealth. On the CMS CY 2026 list of Medicare telehealth services (action: Maintain). (CMS, checked October 30, 2026)
