Her Surgery Is Set for January. Her Broker Learned in August That UnitedHealthcare May Leave Her County in 2027

A 72-year-old has a knee replacement scheduled for the second week of January. Her surgeon, hospital and prior authorization all run through her UnitedHealthcare Medicare Advantage plan. The insurer is part of UnitedHealth Group (NYSE: UNH | UNH Price Prediction). In August, her broker found a preliminary filing showing UnitedHealthcare may leave her county in 2027. The insurance company hasn’t contacted her, and she assumes the approval in her file settles the surgery.

But a green light from her current plan does not settle what a replacement plan will pay. The surgery date remains the same. The coverage behind it may change.

A Preliminary List Names Nearly 3 Dozen Counties

UnitedHealthcare is considering exits from 34 counties in 12 states, potentially affecting about 20,000 members, according to Healthcare Dive. The company stressed that the list was not final. Plan changes will be announced in early October. If her plan is ending December 31, she should look for a separate non-renewal notice dated October 2.

The broker’s list gives her time to investigate. It does not establish that her own plan is ending. The official notice confirms that change and provides evidence she can use when applying for Medigap. She should keep it.

Her Approval Needs a Plan for January

If she joins another Advantage plan, it has its own network and authorization rules. But she may have protection during the switch. CMS requires at least a 90-day transition period for new members already undergoing an active course of treatment, even with an out-of-network provider. During that period, the new plan cannot disrupt that treatment or require a new authorization.

Having surgery on the calendar does not, by itself, establish whether that protection applies. Her surgeon should document the treatment already underway and ask the new plan to confirm in writing how it will cover the January operation.

Networks are the second weak point. Her surgeon may be in the new plan while the hospital, anesthesia group or rehab facility is not. Depending on the plan and any transition protection, out-of-network care may cost more or require a different provider. Premium surcharges tied to a prior year’s income can pile on too, one of several traps we mapped in our free Medicare guide.

Three Paths Before the Plan Year Ends

If her plan is ending, she has three routes to compare.

1. Another UnitedHealthcare plan in her county. Healthcare Dive reports that some affected members could join a different UnitedHealthcare plan. She still needs to check the network and confirm whether her authorization carries over.
2. Another insurer’s Advantage plan. She needs to check its network and find out whether the transition protection covers her treatment, with the holidays falling in the middle of it.
3. Original Medicare, Part D and Medigap. Original Medicare works with doctors and hospitals that take Medicare. She would have no Advantage network to navigate, but her providers still need to confirm coverage for the surgery and recovery care.

A Plan Exit Can Reopen the Medigap Door

At 72, she would normally face medical underwriting for Medigap in most states, and a pending knee replacement could get her denied or charged more. Her Advantage plan leaving her area changes that. If she returns to Original Medicare, federal law gives her the right to buy certain Medigap policies without medical underwriting. She can generally apply starting 60 days before her Advantage coverage ends and for up to 63 days afterward. Higher copays or reduced benefits alone do not create that right.

Which policies she can buy depends partly on when she first became eligible for Medicare. Because she became eligible before January 1, 2020, standard Plan F is among the policies she can consider under this protection. People newly eligible from 2020 onward have access to Plan G instead of Plan F under these federal rules.

She should compare Medigap and Part D premiums before choosing. Her surgeon and recovery providers also need to confirm that Medicare covers the care she needs.

December Still Offers a January Start

Annual Enrollment runs October 15 through December 7, with coverage starting January 1. If her plan is not renewing, a special enrollment period runs from December 8 through the last day of February. Requests received December 8 through December 31 also take effect January 1. Waiting until January pushes the new plan’s start to February 1.

If she does nothing, she generally defaults into Original Medicare without replacement Part D coverage. With surgery scheduled for January, choosing early gives her more time to sort out who will treat her and what the new coverage will pay.

The Surgery Date Is Only One Date That Matters

Three things need to be settled before she heads to the hospital.

1. Confirm coverage for the whole operation. If she chooses another Advantage plan, check the surgeon, hospital, anesthesia group and rehab provider against its 2027 network. Ask how any out-of-network care would be handled.
2. Resolve the authorization question early. Have her surgeon send the existing approval and treatment records to the new plan. Ask whether the transition protection applies or a new authorization is needed. Aim to settle this before December 7 to leave room for problems.
3. Line up medical and drug coverage. If she chooses Original Medicare, apply for an eligible Medigap policy using the nonrenewal notice as proof and request a January 1 start. Enroll in Part D for the same date. December 7 is a useful target; her nonrenewal enrollment period also allows a January 1 Part D start for requests received by December 31.

The broker’s August list gave her an early warning. The official letter tells her whether she needs new coverage. Her surgery may stay on the calendar, but she needs to know who will pay before she reaches the operating room.
