Each Medicare Advantage and Medicare drug plan has a CMS-assigned ID consisting of a Plan ID, Contract ID, and Segment ID. This unique identifier indicates the network type, provider, plan, and region the plan is offered in.[1][2]

They look like this ContractID-PlanID-SegmentID (ex. H8768-015-000 or H8768-015-0).

1. The first letter of the Contract ID indicates the network type:

  • H or 9: Local Managed Care Organizations other than Regional PPO
  • R: Regional preferred provider organization (PPO)
  • S: Stand-alone prescription drug plan (PDP)
  • E: Employer direct plan
  • F: Employer-Directed PDP
  • X: Limited Income Newly Eligible Transition plan

In most cases, you’ll see H and R on Advantage plans and S on stand-alone drug plans.

With H8768-015-000 we can know is not a regional PPO (it happens to be a local PPO).

2. The next part of the contract ID indicates the organization providing the coverage. With H8768-015-000, 8768 is United HealthCare.

3. Next is the plan ID. Plan ID is a unique identifier of the plan. With H8768-015-000, that is AARP Medicare Advantage Walgreens (PPO).

4. Lastly, the Segment ID indicates the region. With H8768-015-000, the 000 indicates select locations in Ohio. Although it is important to note that 000 does not always mean Ohio, the meaning of a Segment ID is unique to a Plan ID/Contract ID combination. TIP: If you don’t see a segment ID, it probably means the plan is offered across the US or there are no regional options (you are essentially looking at the 000 version of the plan).
