Money / coverage
Coverage starts with the exact use.
Get two details from the prescriber: the product’s name and the health condition it is intended to treat. Take those details to the insurer before assuming the medicine will be paid for.
What do I ask my insurer?
Find out if your plan includes that specific product in its formulary. That is the list a plan uses to say which medicines it covers.
Ask whether prior authorization is needed. That means an approval step before the plan agrees to pay for the treatment.
Ask what information the prescriber must send, what you will pay, and whether approval has an end date. Ask how a refusal can be reviewed.
How does Medicare treat weight-loss use?
The September 2026 rules for basic Medicare Part D excluded a drug when its only use was weight loss.
The same drug could be eligible for Part D when used for a different medically accepted condition, such as diabetes.
A treatment reason allowed under Part D rules does not mean your plan has agreed to pay. The plan’s approval requirements and list of covered medicines still apply to the exact product.
Evidence AWhat is the temporary Medicare Bridge?
The Medicare GLP-1 Bridge charged qualifying people $50 for a month’s supply as of September 2026; it applied to certain weight-loss medicines. The programme’s dates were July 1, 2026 to December 31, 2027.
The Bridge handles medicine payments separately from your usual Part D drug plan. In 2026, one programme processor handles approval requests and pharmacy bills. The programme does not change the Part D rule excluding weight-loss-only use.
Its weight-use products include semaglutide (Wegovy) injections and tablets, tirzepatide (Zepbound) KwikPen, and orforglipron (Foundayo) tablets.
For Zepbound, check for the exact name “KwikPen” on the product. The pens and bottles called vials that contain a single dose are not included in the Bridge.
Ask the prescriber and plan how a Bridge request is submitted and which pharmacy can fill it. Do not assume the name of the medicine settles those questions.
Evidence BWho can qualify for the Bridge?
As of September 2026, you must be 18 or older and have a qualifying Medicare drug plan. A separate Part D drug plan can qualify. A Medicare Advantage plan can also qualify if it coordinates care and provides drug coverage.
The programme uses body mass index, or BMI: a number comparing weight with height. Have the prescriber review the health conditions and BMI recorded at the start of GLP-1 treatment. A BMI at or above 35 can satisfy the weight rule on its own, without another health condition.
At a BMI of 30 or higher, eligibility requires one of three conditions. Heart failure with preserved ejection fraction belongs on that list. This means the share of blood leaving the heart with each squeeze stays normal. Ask the doctor to confirm that exact diagnosis. Kidney disease that is long term and at least stage 3a is another. The remaining condition is blood pressure above 140 (top reading) or above 90 (bottom reading) that persists while taking two blood-pressure medicines.
For the BMI threshold of 27 or higher, pre-diabetes is one qualifying condition. A past stroke also qualifies, as does a past heart attack. Symptoms caused by disease of the arteries supplying the limbs are another qualifying condition. Pre-diabetes describes a raised blood-sugar level that has not reached the range for diabetes.
The Bridge excludes type 2 diabetes. Moderate to severe obstructive sleep apnea also prevents Bridge eligibility. With that illness, breathing becomes blocked again and again while the person sleeps. MASH is excluded too: this fatty-liver illness involves scarring that is moderate to advanced, without cirrhosis. Cirrhosis means severe liver scarring. These treatment reasons use the usual Part D process instead. A prescription to reduce serious heart and stroke risks also goes to the Part D plan.
A 2026 payment by Part D for your GLP-1 treatment prevents you from using the Bridge in 2026. You need a prescription and approval before payment. The prescription must include ongoing food and physical-activity changes. Ask your plan and prescriber to confirm every condition before you rely on the programme.
You pay the $50 each month. That spending does not count toward your yearly patient-payment limit under Part D. Coupons and Medicare’s extra help for people with low incomes cannot lower that payment.
