Medicare Supplement Insurance for Crohn's Patients: What's Covered and How to Get Approved
Medicare supplement insurance for Crohn's patients closes the 20% gap that Original Medicare leaves on infusions, colonoscopies, and specialist visits. If you're tired of fighting with insurance every time your treatment changes, a Medigap plan locks in predictable costs so you can focus on managing your health instead of managing paperwork.

Part B covers 80% of outpatient Crohn's care after you meet the $283 annual deductible. That includes provider-administered biologics like Remicade infusions, diagnostic colonoscopies, and GI specialist visits.
The remaining 20% is yours. On a biologic that runs $5,000+ per infusion every 8 weeks, that 20% adds up to thousands a year. Part A covers inpatient hospital stays with a $1,676 deductible per benefit period.
Which Medigap plans eliminate the 20% coinsurance on specialist visits
- Plan G — Covers 100% of Part B coinsurance, Part A deductible, skilled nursing facility costs ($209.50/day for days 21-100), and excess charges. You only pay the $283 Part B deductible.
- Plan N — Similar to G but with up to $20 copays at some office visits and a slightly lower premium. Good if your infusions are your biggest cost.
- Plan F — Only available if you were eligible for Medicare before January 1, 2020. Covers everything G covers plus the Part B deductible.
For Crohn's patients getting regular infusions, Plan G usually offers the best value. Rates vary by carrier, age, and ZIP code.
Underwriting with Crohn's: carriers that approve IBD applicants
Outside Open Enrollment, most Medigap carriers ask health questions. Crohn's disease and ulcerative colitis can trigger a decline with some companies. But not all carriers treat IBD the same way.
Some carriers approve applicants whose Crohn's is stable, meaning no hospitalizations or surgery within the past 12-24 months. Others decline any active IBD diagnosis. The carrier mix varies by state. That's why working with a broker who knows which companies to submit to matters. One denial doesn't mean you're out of options.
Guaranteed-issue paths that bypass medical questions entirely
Three situations give you guaranteed-issue rights, meaning no health questions, no denials:
- Medigap Open Enrollment — 6 months starting when you're 65+ and enrolled in Part B. This is your best window. Apply as early as 6 months before Part B starts to lock in your rate.
- Leaving a Medicare Advantage plan — Within your first 12 months on MA, you can switch to Original Medicare + Medigap with guaranteed-issue rights.
- Losing employer or union group coverage — Federal law gives you guaranteed-issue access to certain Medigap plans.
What about Part D and biologic prescriptions?
Here's where many Crohn's patients get caught off guard. Medigap does not cover prescription drugs. If your biologic is self-administered (like Humira injections at home), it falls under Part D, not Part B. Part D formularies and costs vary widely by plan.
Manufacturer assistance programs and Extra Help (Low-Income Subsidy) can reduce Part D costs significantly. We help you compare Part D plans alongside your Medigap so nothing slips through the cracks.
