Does Medicare cover Zepbound?
Short answer: Yes, two ways. For weight loss under the Bridge's BMI tiers: $50/month — but only the KwikPen form. For moderate-to-severe obstructive sleep apnea: through your Part D plan under Zepbound's OSA indication, with plan-specific terms. Your diagnosis picks the path: moderate-to-severe OSA routes you to Part D; otherwise the Bridge applies.

The two paths, and the trap in each
Bridge path (weight loss): flat $50, nationwide — with the KwikPen-only rule as the trap. Vials and single-dose pens won't process; the prescription should say KwikPen explicitly. Part D path (sleep apnea): plan formulary terms, typically requiring your sleep-study documentation — with severity as the gate: moderate-to-severe OSA (AHI 15+) is what carries the indication and what routes you out of the Bridge. Mild sleep apnea does neither — you'd use the Bridge under normal BMI tiers.

Common questions
Why was my Zepbound fill quoted at hundreds of dollars?
Usually the form (not KwikPen) or the claim routing (sent to your Part D plan instead of the Bridge processor). Both are fixable — see our pharmacy troubleshooting guide.
I have mild sleep apnea and BMI 32 with prediabetes. Which path?
Mild OSA doesn't route you anywhere — you'd apply under the Bridge (prediabetes qualifies at BMI 27+, so BMI 32 with prediabetes fits Tier 3).
Does the KwikPen rule apply on the sleep-apnea path too?
The KwikPen restriction is a Bridge program rule. On the Part D path, your plan's formulary determines which presentations it covers — check with your plan or pharmacist.
