You've got the basics right. Here's the detailed picture for 2026:

Traditional Medicare Part D:

• Covers GLP-1s for diabetes indication ONLY (Ozempic, Mounjaro, Trulicity)
• The $2,000 annual OOP cap is in effect — once you hit that, you pay $0 for the rest of the year
• With the OOP cap, even expensive drugs like Ozempic become effectively cheaper in the back half of the year
• Weight-loss-only GLP-1s (Wegovy, Zepbound) remain excluded from Part D by statute — Medicare literally cannot cover them for obesity alone

Medicare Advantage (Part C):

• Some MA plans have started offering supplemental benefits that include weight management drugs
• Humana and UHC Medicare Advantage have specific plans in certain markets with limited GLP-1 coverage for weight loss
• This varies wildly by geography — check your specific plan

The Treat and Reduce Obesity Act has been introduced multiple times but as of early 2026 has not passed. If it does, it would allow Medicare Part D to cover FDA-approved anti-obesity medications. But don't hold your breath.

Thank you for that breakdown. So for my situation — T2D plus obesity — my doctor has Ozempic prescribed for the diabetes, which Part D covers. But $380/month copay is brutal on a fixed income.

With the $2,000 cap, that means I'd hit my max out of pocket around month 5-6, and then pay nothing the rest of the year? Am I understanding that right?

Also wondering if I should look at Medicare Advantage plans for next enrollment period. I'm currently on original Medicare + a Medigap plan + standalone Part D.

Yes, your math is right. At $380/month, you'd hit the $2,000 OOP cap in about 5.3 months. After that, you'd pay $0 for Ozempic for the remaining 6-7 months. So your total annual cost for Ozempic would be capped at $2,000.

Also — have you looked at your Part D plan's formulary tier for Ozempic? The copay varies significantly between plans. During Open Enrollment (Oct 15 - Dec 7), you can use the Medicare Plan Finder tool at medicare.gov to compare plans. Some Part D plans have Ozempic at a lower tier with copays around $95-150/month.

Regarding Medicare Advantage: it's a big tradeoff. You'd give up your Medigap plan and original Medicare's provider flexibility. MA plans have networks, prior auth requirements, and can change benefits annually. For some people it's worth it, for others the restrictions are dealbreakers.

I'm on a Humana Medicare Advantage plan in Florida. They cover Ozempic for my diabetes with a $47 copay per month. Much better than what you're paying, InsuranceTom.

The catch: I had to get a prior auth (took about 2 weeks), I'm limited to their preferred pharmacy (CVS), and they required documentation of failed metformin therapy first. But $47/month is very manageable.

For what it's worth, I also asked about Wegovy for the weight loss component and they flatly denied it. My plan's supplemental benefits cover nutrition counseling and a gym membership but not weight loss medication. Baby steps, I guess.
