Ask about approval before the fill
A plan calls its covered-medicine list a formulary. Prior authorization means asking the plan to agree to coverage before a prescription is filled.
Regular Medicare drug coverage may pay for certain weight medicines used for another accepted medical purpose, as of September 26, 2026. Examples include type 2 diabetes, reducing heart risks or treating certain sleep-related breathing problems. [a]
Being eligible for coverage does not mean that a particular plan has agreed to pay. [a]
Ask about your share of the bill, required paperwork and what happens if the request is denied.
Medicare has a separate temporary route
GLP-1 is a hormone: a chemical message in your body that affects appetite and blood sugar. GLP-1 medicines act like that message. Certain weight medicines have a temporary payment route called the Medicare GLP-1 Bridge. [b]
As of September 26, 2026, eligible participants pay $50 for a monthly supply through this programme, which includes specified shots and tablets. [b]
Outside the normal Medicare drug benefit, it opens on July 1, 2026, and continues through December 31, 2027. [b]
The age rule is 18 or older. You need a prescription, an approval request and ongoing food and physical-activity changes as part of treatment. [c]
The health rules use body mass index, or BMI, a number based on weight and height. The prescriber checks it at the time this treatment began. [c]
The weight rule can be met with a BMI at or above 35. [c]
For a BMI of 30 or higher, one qualifying problem is the heart-failure type known as “preserved ejection fraction”. Ask the prescriber whether that is the type in your record. [c]
Kidney disease at stage 3a or worse can also qualify at that BMI. Ask the prescriber which stage, or severity level, is in your record. [c]
Blood pressure can qualify at that BMI if it stays high despite two blood-pressure medicines. The upper reading must be above 140 or the lower above 90. [c]
At a BMI of 27 or higher, prediabetes qualifies, as do a previous stroke, a previous heart attack or artery disease with symptoms. Artery disease here means poor blood flow outside the heart, such as in the legs. [c]
Prediabetes means blood sugar is high but below the diabetes range. Ask the prescriber to match your medical records to the programme’s exact rules. [c]
You need either a standalone Medicare Part D drug plan or Medicare Advantage with drug coverage from a plan type that qualifies. Have your plan verify that its type qualifies. [c]
If a GLP-1 medicine was paid for by your Part D plan during 2026, the Bridge is unavailable to you in 2026. [c]
Regular drug coverage handles type 2 diabetes, a specific advanced form of fatty liver disease, and sleep apnea that is moderate or severe. Sleep apnea is when a person repeatedly stops breathing while asleep. [c]
A prescription to reduce heart risks also goes to your regular drug plan. Ask the prescriber and plan which set of payment rules applies to you. [c]
The programme’s spending is separate
As of September 26, 2026, Bridge payments do not count toward your regular Medicare drug deductible or yearly spending limit. [b]
A deductible is the amount you pay before your plan starts paying certain costs. The yearly spending limit caps the payments that count under the plan’s rules. Ask which payments count.
The Bridge gives no extra payment help to low-income participants. Coupons cannot be used to reduce a Bridge payment. [b]
Ask about a savings offer’s limits
As of September 26, 2026, the weight-drug savings cards in this check require commercial insurance, such as workplace or private cover. [d]
People with Medicare, Medicaid or military coverage cannot use these insurance savings cards. The cards reduce the patient’s share of an insured bill. [d]
A maker’s cash-price offer is different: you pay outside insurance. People with government coverage can use some of these cash offers. Check the terms of the exact offer. [d]
Ask which offer is being quoted, whether you qualify, and what happens when its terms end.
