What G0108 covers
G0108 represents individualized diabetes self-management training delivered one-on-one, commonly by a diabetes care and education specialist or another qualified educator in an outpatient setting. Instruction may address blood glucose monitoring, medication and insulin routines, meal planning, physical activity, and recognizing or responding to hypoglycemia. The service is part of a structured diabetes education program, rather than a brief discussion incidental to an office visit.
Report the code in 30-minute units for individual training time. Documentation should identify the education provided, the patient’s needs and learning goals, and the time spent in the training; keep time for a separately furnished service distinct. G0109 is the group-training counterpart, so select between the codes according to whether instruction was individual or delivered in a group. CMS’s supplied payment facts list no additional code-specific payment rule for G0108.

- 97802 reports an initial medical nutrition therapy service, not the broader one-to-one diabetes self-management education represented by G0108.

- 97803 reports follow-up medical nutrition therapy. G0108 is individual diabetes self-management training, which may cover topics beyond nutrition.
G0108 billing questions
When should G0108 be used instead of G0109?
Use G0108 for one-to-one diabetes self-management training. G0109 is for training delivered in a group.
How are units counted?
Report G0108 in 30-minute units of individual training. Document the training time and the education delivered.
Can an office visit be reported on the same date?
A separately furnished and documented evaluation or management service may be distinct from the training. Do not include the same work or time in both services.
Does meal-planning instruction belong under G0108?
Meal planning can be part of diabetes self-management training. A separately furnished medical nutrition therapy service is distinct and should be documented as such.
What should the training note include?
Record the individual instruction provided, the patient’s relevant learning needs or goals, and the time spent. The note should make clear that the service was diabetes self-management training, not a brief incidental discussion.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
