Summary & Overview
HCPCS G9883: MDPP Ongoing Maintenance Sessions (Months 16–18)
HCPCS Level II code G9883 represents two Medicare Diabetes Prevention Program (MDPP) ongoing maintenance sessions attended by a beneficiary in months 16–18 under the MDPP Expanded Model. The sessions are approximately one hour each, adhere to a CDC‑approved DPP maintenance curriculum, and require in‑person weight measurement documenting at least 5% weight loss from baseline. Nationally, this code matters as MDPP maintenance services support long‑term weight management and diabetes risk reduction among Medicare beneficiaries, aligning program compliance with CMS coverage rules and CDC standards.
Key payers included in this overview are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn the clinical definition and service setting for G9883, which payers commonly cover MDPP services, and the policy context linking session timing and weight‑loss documentation to MDPP program requirements. The publication also summarizes benchmarks and reimbursement considerations where available and highlights updates relevant to MDPP expanded model delivery and maintenance‑phase reporting.
This summary is intended for national audiences including providers, payers, and program administrators seeking concise guidance on the purpose, timing, and documentation expectations tied to HCPCS Level II code G9883.

Clinical & Coding Specifications
Clinical Context
A 58-year-old beneficiary enrolled in the Medicare Diabetes Prevention Program (MDPP) expanded model completed two Ongoing Maintenance Sessions (MS) during months 16–18 of the MDPP service period. These are approximately 1-hour, in-person sessions that follow a CDC-approved DPP maintenance curriculum. At one of the sessions the beneficiary had an in-person weight measurement documenting maintenance of at least 5% weight loss from baseline. The clinical workflow typically includes scheduling the maintenance sessions during the months 13–24 window, conducting an in-person group or individual maintenance counseling visit led by an MDPP supplier (e.g., lifestyle coach), measuring weight and documenting the percentage change from baseline, delivering curriculum content focused on long-term behavioral strategies, and entering attendance and weight outcomes into the MDPP reporting system for Medicare reimbursement using the HCPCS Level II code G9883. Administrative staff append appropriate modifiers when needed for billing, and the MDPP supplier maintains participant progress records to support coverage and quality reporting.
