In Switching to Original Medicare, Beware of Medigap Plan Refusals

Why It Matters

Denial of Medigap coverage can leave seniors exposed to high out‑of‑pocket costs, undermining the affordability of switching from Medicare Advantage. Understanding guaranteed‑issue rights is critical for maintaining continuous, comprehensive health coverage.

Key Takeaways

• Medigap insurers can deny coverage via medical underwriting.
• Certain states guarantee Medigap without underwriting year-round.
• Switching from MA to Original Medicare triggers special enrollment windows.
• Insurers increasingly use prescription drug history for underwriting decisions.
• SHIP counselors help navigate guaranteed issue rights and plan options.

Pulse Analysis

Medicare Advantage enrollment remains a pivotal moment for millions of seniors, as plans often promise lower premiums and extra benefits like vision or hearing coverage. Yet recent profit squeezes have forced many insurers to exit markets, leaving up to one in ten members without a viable plan. This churn drives a growing number of beneficiaries to consider Original Medicare, hoping to regain broader provider access and avoid restrictive prior authorizations. The decision, however, carries hidden complexities, especially around supplemental coverage.

A Medigap policy can bridge the cost gaps left by Original Medicare, but insurers traditionally reserve the right to underwrite applicants based on health status. Federal law grants a six‑month guaranteed‑issue window for newcomers to Part B, after which most applicants face underwriting scrutiny. Exceptions exist: Connecticut, Massachusetts, New York, and Maine offer year‑round guaranteed issue, and special enrollment periods protect those displaced by plan terminations or relocations. These safeguards are vital because underwriting can reject or surcharge policies for conditions ranging from diabetes to cancer, dramatically increasing out‑of‑pocket expenses.

Navigating this landscape requires expert guidance. State Health Insurance Assistance Programs (SHIP) provide free, unbiased counseling to pinpoint eligibility for guaranteed‑issue windows and identify insurers with more lenient underwriting criteria. As insurers lean heavily on prescription‑drug histories to assess risk, SHIP counselors can also recommend plans that prioritize broader coverage. For seniors, leveraging these resources can mean the difference between affordable, comprehensive health protection and costly coverage gaps, reinforcing the importance of proactive planning during Medicare’s enrollment cycles.
