The Medicare Diabetes Prevention Program vs health coaching codes: which fits your organization?
MDPP and the 0591T–0593T coaching codes both use coaches to drive behavior change, but they work in opposite ways: MDPP suppliers enroll and bill Medicare directly, while coaching codes are billed by a supervising practitioner.
Community organizations and lifestyle programs often ask whether the new health coaching codes replace the Medicare Diabetes Prevention Program (MDPP). They don't. They're different payment pathways with different rules, and an organization might use one, the other, or both.
The key difference: who bills
MDPP is a Medicare program in which an organization enrolls as an MDPP supplier and bills Medicare itself for a structured, CDC-recognized diabetes prevention curriculum delivered by trained coaches.
Health coaching codes 0591T–0593T are incident-to services. A qualified coach furnishes them under the general supervision of a physician or other practitioner, and only the supervising practitioner bills (42 CFR 410.26(b)(5)(v)). The coach's organization doesn't bill these codes itself.
Side by side
| MDPP | Health coaching codes | |
|---|---|---|
| Who bills Medicare | The enrolled MDPP supplier | The supervising practitioner |
| Program design | Fixed, CDC-recognized curriculum for prediabetes | Patient-centered coaching toward goals the patient sets; not condition-specific |
| Eligibility | Beneficiaries meeting prediabetes lab and BMI criteria | Reasonable and necessary, linked to the practitioner's plan of care |
| Payment basis | Program codes tied to attendance and outcomes | Per session (0591T, 0592T) or per beneficiary per group session (0593T) |
| Practitioner role | Not required to supervise each session | Supervises (general supervision) and bills |
| Personnel | Trained lifestyle coaches meeting MDPP coach requirements | Auxiliary personnel with appropriate certification (pathways include NBHWC, NCHEC CHES® eligibility, AHNCC, and OAA program training) |

Which fits?
- An organization already running a CDC-recognized lifestyle change program may prefer MDPP for prediabetes, because it can bill directly.
- A practice with patients across many conditions (hypertension, obesity, chronic pain, post-diagnosis lifestyle change) may find the coaching codes more flexible, since they aren't tied to one curriculum.
- A CBO partnering with a practice may use the coaching codes through general supervision; the final rule explicitly lets CBO-affiliated coaches furnish coaching (pp. 383–384).
Running both
If a beneficiary is in MDPP and also receives coaching under 0591T–0593T, keep the services clearly separate in scheduling and documentation, avoid counting the same session twice, and confirm with your MAC how overlapping services will be reviewed. The final coaching rule doesn't address MDPP.
