Plan the bill
Will insurance help with the bill?
Ask your plan about the reason for the prescription and the exact product. Keep the medicine question separate from whether the visit is covered.
Get a product-specific answer
Check the formulary, the list showing which medicines your plan covers. Prior authorization means getting the plan’s agreement to pay ahead of time. Ask whether either applies to the proposed prescription.
Ask what you pay for the medicine, the visit, and any requested tests. Ask whether a particular pharmacy must fill the prescription. Write down who gave you the coverage answer.
Medicare’s usual drug benefit has limits
As of September 2026, ordinary Medicare Part D excludes medicines when used for weight loss. Medicare calls its prescription-medicine insurance Part D.
The same drug can be eligible for Part D coverage when used for another accepted medical purpose, such as diabetes. Eligibility for coverage does not guarantee that a particular plan will cover it.
A separate, temporary Medicare programme
Dates, access and the monthly payment
The Medicare programme called the GLP-1 Bridge gives eligible Part D members access to certain weight-loss medicines for a $50 monthly copay, as of September 2026. The programme’s start date is July 1, 2026, and its end date is December 31, 2027. Its pharmacy bills are handled separately from your usual Part D medicine bills.
GLP-1 is a chemical message that helps the body control blood sugar and hunger. The Bridge name uses that term for the medicines it includes. Under the September 2026 terms, you must be 18 or older and meet the programme’s weight and health requirements. Your plan type must qualify, and you need a prescription and approval for payment in advance.
Weight and health checks
BMI uses your height and weight to produce a number. The Bridge accepts a BMI of 35 or more, or a lower BMI with certain health problems.
With a BMI of 30 or more, you need one of three health problems. They are heart failure where the heart still squeezes normally, kidney disease at stage 3a or later, or uncontrolled high blood pressure. For the blood-pressure test, even with two blood-pressure medicines, the top number must be above 140 or the bottom number must be above 90. Ask your health professional to check your kind of heart failure or stage of kidney disease.
With a BMI of 27 or more, you need one of these: prediabetes; a heart attack or stroke in the past; or poor blood flow in limb arteries that causes symptoms. Prediabetes means blood sugar is high but not high enough for type 2 diabetes. These checks use your health when you began this type of medicine.
Who uses ordinary Part D instead
Type 2 diabetes, moderate or severe sleep apnea, and certain liver disease with scarring are excluded from the Bridge. Those uses go through ordinary Part D instead. Sleep apnea means breathing repeatedly pauses during sleep. Ask your plan and the person prescribing your medicine which programme fits your health problem.
If your GLP-1 medicine was already paid for by Part D in 2026, the Bridge is unavailable to you in 2026. This means an insurance payment, not just having taken the medicine before.
How Bridge payments are counted
Under the September 2026 terms, your $50 Bridge payments do not reduce what you owe toward Part D’s yearly spending limit. Reaching that limit does not remove the Bridge copay. The Bridge gives no extra price reduction for low income. Check your situation with your plan or the person prescribing your medicine. The official Bridge page is on the further-reading page.
A savings card and a cash offer differ
As of September 2026, drug makers’ savings cards for these weight and diabetes medicines require private or workplace insurance. Those cards exclude people whose coverage is Medicare, Medicaid, or military insurance.
A drug maker’s cash offer is a price for people paying for the medicine themselves, outside insurance. Medicare members may be able to use that price even though they cannot use the savings card. Ask about the terms of the particular offer.
