At 73, UnitedHealthcare Will End Her Medicare Advantage Plan for 2027. If She Ignores the Letter, She’ll Wake Up January 1 With Original Medicare, No Drug Plan and No Medigap

The envelope from UnitedHealthcare states in bold letters “plan non-renewal.” Imagine a 73-year-old member reads the first paragraph, sets the letter on the counter and figures Medicare will move her into something comparable for 2027. Medicare will not do that for her. On January 1, she lands in a coverage setup with real holes, and one of them can turn into a penalty she pays for life.

UnitedHealth Group (NYSE:UNH | UNH Price Prediction) said its 2027 UnitedHealthcare Medicare Advantage plans will boost the number of limited provider networks, which are narrower by nature. A non-renewal notice from any carrier starts the same clock. If your plan only changed its benefits or network, you keep your coverage and can shop on the normal schedule.

What She Wakes Up With on January 1

If the member does nothing, she goes back to Original Medicare when the Advantage plan ends. Parts A and B continue. Medicare does not automatically add a stand-alone Part D plan or a Medigap policy.

Original Medicare has no out-of-pocket maximum. She pays 20% of Part B charges with no ceiling. A hospital admission costs her the Part A deductible of $1,736 per benefit period, and days 61 through 90 cost $434 a day. If she goes 60 days without inpatient hospital or skilled nursing care, the next admission starts a new benefit period and another deductible.

Going Without Drug Coverage Costs Her Twice

With no Part D plan or other creditable drug coverage, she can be left paying full price for most of her retail prescriptions starting January 1. On the other hand, with a Part D plan, the most she pays out of pocket for covered drugs in 2027 is $2,400, up from $2,100 in 2026. Once she reaches that cap, covered drugs cost $0 for the rest of 2027.

The second cost can last for life. If she goes 63 consecutive days without creditable drug coverage, Medicare adds a late enrollment penalty equal to 1% of the national base beneficiary premium for each full month she went uncovered. If she waits until next fall’s open enrollment and starts Part D in January 2028, 12 uncovered months mean a 12% penalty. The dollar amount will depend on the national base beneficiary premium in effect then, and it can change from year to year (it is one of several subtle rules that drain retirement budgets, and we mapped out the rest in a free guide to Medicare’s hidden bills).

A Rare Medigap Opening Comes With Her Letter

At 73, buying Medigap can normally mean answering health questions in many states. Her plan’s non-renewal gives her something valuable instead: guaranteed-issue rights if she returns to Original Medicare. Federal rules let her buy certain Medigap plans, including Plan F, regardless of health. She can apply as early as 60 days before her Advantage coverage ends and no later than 63 days after. The non-renewal letter serves as proof and should be kept.

State law can expand the federal list of plans. New York, Connecticut, Massachusetts and Maine offer broader guaranteed issue. Her State Health Insurance Assistance Program can identify which plans she can buy without health questions. When the 63-day window ends, so does her best chance to get Medigap without underwriting.

Her Special Enrollment Window Has a Catch

The non-renewal opens a Special Enrollment Period from December 8, 2026 through the last day in February. The catch: coverage starts the first day of the month after the plan gets her request. That one-month gap would cost her at the pharmacy, but by itself it would not reach the 63-day mark that triggers the Part D penalty.

Three Moves to Make Before December 7

1. Run her prescriptions through Medicare Plan Finder this month. Price replacement Advantage plans and stand-alone Part D plans side by side. Confirm each doctor is in network, since carriers are narrowing 2027 networks.
2. If she is healthy and her doctors are in a replacement Advantage plan, enroll by December 7. Check the in-network out-of-pocket maximum first. That cap leaves out drug costs, and out-of-network care may follow a separate limit. If she leaves the plan later, she may face medical underwriting for Medigap.
3. If she is healthy and her doctors are in a replacement Advantage plan, enroll by December 7. Check the in-network out-of-pocket maximum first. That cap takes out drug costs and out-of-network care. If she leaves the plan later, she will face medical underwriting for Medigap.

The letter on her counter works as a deadline notice. If she acts by December 7, she gets coverage on January 1 with no gap.
