Why So Many Plans Are Leaving in 2026
The Medicare Advantage market has undergone significant contraction since 2024. Multiple large insurers reduced or eliminated their service areas in markets they deemed unprofitable, citing the following:
- Rising medical costs that outpaced CMS reimbursement rate increases
- Stricter CMS risk adjustment audits reducing overpayment revenue streams
- Increased scrutiny of prior authorization and denial practices
- Higher-than-projected utilization by enrollees after COVID-era care deferrals
The result: markets that were saturated with $0-premium plans are now thinner, and beneficiaries who built their healthcare routines around a specific plan are being forced to start over.
⚠️ This is time-sensitive. If you received a plan termination notice, your SEP window is limited. Act within the timeframe stated in your notice. Do not wait until the Annual Enrollment Period opens — your SEP may give you more options and better Medigap access.
How to Find Out If Your Plan Is Leaving
- Check your mail—Plans must notify you at least 90 days before termination. Look for an “Annual Notice of Change” or termination letter from your insurer.
- Go to Medicare.gov — Use the plan finder tool to look up your current plan and see its 2026 availability in your zip code.
- Call 1-800-MEDICARE (1-800-633-4227) — Representatives can confirm whether your plan is available in your area for the coming year.
- Call your plan directly — Member services can confirm plan availability and your SEP options.
Your Options When Your Plan Leaves
When a Medicare Advantage plan leaves your service area or terminates its Medicare contract, you automatically receive a Special Enrollment Period. You have three main options:
Option 1: Enroll in a Different Medicare Advantage Plan
If other MA plans are available in your area, you can enroll in one. Compare carefully—check that your current doctors are in-network, review the OOP maximum, and read the plan’s prior authorization requirements. Don’t assume the replacement plan offers the same benefits or network as the plan you’re losing.
Option 2: Return to Original Medicare
You can switch back to Original Medicare Parts A and B. This gives you unrestricted provider access nationwide. You’ll need to add a standalone Part D drug plan separately.
Option 3: Get Medigap — With Guaranteed Issue Rights
This is the most valuable option for many beneficiaries. When your MA plan leaves your area, you have a federal guaranteed issue right for Medigap—meaning insurers cannot deny you a Medigap policy or charge more based on your health conditions. This is the same protection you had when you first turned 65.
💡 This is a rare second chance. For beneficiaries who chose Medicare Advantage at 65 and have since developed health conditions, a plan exit is one of the only ways to get Medigap without underwriting. Use this window wisely — apply for Medigap before your MA plan ends.
Step-by-Step Action Plan If Your Plan Is Leaving
- Read your termination notice carefullyNote the effective date of termination and the deadline for your SEP. These dates govern your window to act.
- Decide: MA, Original Medicare, or Medigap? If you have significant health conditions, this is your best opportunity to secure Medigap guaranteed issue rights. If you’re healthy and cost-focused, evaluating new MA plans makes sense.
- If choosing Medigap: apply immediately Contact Medigap insurers or a licensed broker to apply for Plan G or Plan N. You have 63 days from your plan’s termination date to use your guaranteed issue right.
- Enroll in Part D at the same time Whether you choose Original Medicare or a new MA plan, confirm your drug coverage is in place. Don’t leave a gap — even one month without Part D can eventually trigger a penalty.
