New Bridge plan for Medicare covers weight-loss drugs

Medicare has never been allowed to pay for a drug used for weight loss, but a temporary program that opened July 1 changes that.

Patients who qualify pay $50 a month for GLP-1 drugs. According to Medicare, the program covers the Foundayo tablet, Wegovy as injection or tablet, and the Zepbound KwikPen. Single-dose Zepbound vials and pens are not included.

Eligibility starts with a body mass index of 35 or higher, measured when treatment began. Lower numbers can qualify with certain conditions — 30 with uncontrolled high blood pressure or stage 3a kidney disease, or 27 with prediabetes, a heart attack, or stroke.

The $50 does not count toward a Part D deductible or out-of-pocket limit, Extra Help cannot reduce it, and it cannot be spread across the year through the Medicare Prescription Payment Plan.

A doctor sends the prescription and files a prior authorization. Approved patients get a letter in the mail, and the authorization holds through December 31, 2027.

According to Medicare, adults are not eligible for the new GLP-1 Bridge program if they have type 2 diabetes, moderate-to-severe sleep apnea, or advanced fatty liver disease. Anyone already getting a GLP-1 through a Part D plan is also excluded.

The reason is a quirk in the law. Medicare is barred from covering drugs used for weight loss, but not drugs used to treat a disease. People being treated for diabetes, sleep apnea, or liver disease have a route to these drugs through Part D. The Bridge exists for people whose only reason to take the drug is weight.

The Bridge is not part of a Part D drug plan, so there is nothing to shop for during Open Enrollment. For anyone who qualifies, the drug plan does not matter. For those excluded because a doctor is treating one of those other conditions, the Part D plan matters enormously — the drug has to appear on that plan's formulary. If it does not, the patient pays the full retail price, and none of it counts toward the annual out-of-pocket limit. Checking the formulary is worth doing before Open Enrollment closes.
