Mid-Year Move From an MA Plan to Medigap
Ethan is 68 and enrolled in a Medicare Advantage HMO in Ohio. On June 1 he moves permanently to Arizona to live near his son. His Ohio HMO does not operate in Arizona, and his cardiologist is not in any Arizona network. Ethan has hypertension and sees a cardiologist twice a year; his medications are stable. He wants to switch to Original Medicare plus a Medigap Plan G and a standalone Part D plan. He has not had a Medigap policy before and has been in the MA plan for three years. He asks whether he can buy Plan G without answering health questions and what enrollment deadlines apply. He also asks whether he can keep the Ohio MA plan until he finds new doctors.
1. Does Ethan have a guaranteed issue right for Medigap after moving? Explain the conditions and the timing, and note any limits.
Read the worked answer
Ethan likely has a federal Medigap guaranteed-issue right because he is moving out of his MA plan’s service area and the plan will not serve his new address. The protection is time-limited, generally 63 days before through 63 days after coverage ends, so he must act quickly. Important limit: federal guaranteed issue does not require every Medigap plan. Insurers must offer certain plans, typically A, B, K, and L for someone in his situation; Plans C and F are closed to people newly eligible after 2020. Plan G is not federal guaranteed issue, so the insurer may underwrite. He also has an MA SEP and a Part D SEP tied to the move, but those do not force a Medigap insurer to sell Plan G.
2. Ethan wants Plan G specifically. What should the agent tell him about Plan G versus the guaranteed-issue plans, and what alternative path would you recommend?

Tell him that insisting on Plan G may forfeit the guaranteed-issue advantage. He can use the guaranteed-issue right to buy an available plan such as A, B, K, or L without health questions, then choose a Part D plan. If he wants Plan G, he can apply and see whether the insurer underwrites, but hypertension could lead to a decline or higher premium; he should not cancel the Ohio MA plan until the new coverage is approved and effective. A practical path is to apply for Plan G while preserving the guaranteed-issue option within the 63-day window; if declined, accept a guaranteed-issue plan rather than go uncovered. He should compare the total cost of Plan G plus Part D against Plan K or L plus Part D.
3. What enrollment steps and deadlines should Ethan follow to avoid a gap in coverage and a Part D penalty?
Read the worked answer
Coordinate the move. Notify the Ohio HMO before or at the move and ask for a disenrollment date at the end of the month, then apply for Arizona coverage effective the first of the next month to avoid a gap. His MA move SEP and Part D SEP generally give him a two-month window, but the Medigap guaranteed-issue window is 63 days, so the Medigap application should be started immediately. If he goes without creditable drug coverage for 63 days or more, a Part D late enrollment penalty can apply. Keep proof of the move, the plan’s service-area denial, and the disenrollment confirmation. If he keeps the Ohio HMO after moving, routine non-emergency care in Arizona may not be covered, so that is not a safe long-term solution.
