    The CMS 2027 plan crosswalk, dated October 1, 2026, links HealthSpring Assurance Rx (PDP), plan ID S5617-221, to plan ID S5715-034 for 2027, and the plan keeps its name. Its status is Renewal Plan, not New Plan or Terminated/Non-renewed Contract, and the CMS 2027 Landscape file lists S5715-034 in Michigan, so this stand-alone Medicare drug plan continues in Michigan in 2027. Under the crosswalk, its members are moved to S5715-034 unless they choose another plan. The ID changes because the plan moves from CMS contract S5617 to contract S5715, where its plan number is 034. In October 2026, 56,008 Michigan residents were enrolled in it, 10,264 of them in Wayne County. This page shows where its members live, what the new plan ID means and how to compare drug plans before December 7.

    What the new plan ID means for you

    S5715-034 is the 2027 ID of the same drug plan: CMS lists it as a renewal of S5617-221, not as a new plan. In Michigan, HealthSpring Assurance Rx (PDP) appears as S5617-221 in the CMS 2026 Landscape file and as S5715-034 in the 2027 file, with Health Care Service Corporation as its parent organization in both, so a 2027 letter or plan comparison that shows S5715-034 is about this plan. It renews automatically on January 1 with every change listed in its Annual Notice of Change (ANOC), which can include the premium, the deductible, the pharmacies and the drug list, so read yours before December 7; our guide to the ANOC letter shows what to check first. Another HealthSpring drug plan, HealthSpring Extra Rx (PDP) S5617-363, is not offered in Michigan in 2027, and the crosswalk does not move its members into this plan.

    Comparing drug plans for 2027

    If the plan still suits you after its 2027 changes, you can let it renew. If it does not, you can switch during the Annual Enrollment Period, October 15 through December 7, to another stand-alone drug plan or, if you would rather leave Original Medicare, to a Medicare Advantage plan that includes drug coverage, where one is offered in your county, and the new plan starts January 1. Michigan has 11 stand-alone drug plans in the CMS 2027 Landscape file, down from 12 in 2026. Drug plans differ in premiums, deductibles, pharmacies and which drugs they cover, so the useful comparison runs your own prescriptions through each plan. Our guide to Part D premiums in 2027 explains what drug plans cost. Goulson Insurance does not offer every plan; Medicare.gov and 1-800-MEDICARE list all of them, and 1-800-MEDICARE is available 24 hours a day, 7 days a week.

    Check another plan ID

    Your Annual Notice of Change lists what changes for 2027, such as the premium, the deductible, the pharmacies and the drug list.
