Ask about the plan's drug list and approval step
A formulary is the list an insurance plan uses to show which medicines it covers. The agreement to pay that a plan requires before a prescription is filled is called prior authorization.
Ask whether the proposed product is on that list, what paperwork is needed and what you would pay.
Medicare has separate drug coverage
Medicare is federal health insurance; its usual drug benefit is called Part D.
From the record
Medicare's usual weight-loss exclusion remains
As of September 2026, ordinary Medicare drug coverage excludes drugs used only for weight loss. A drug prescribed for another accepted reason, such as diabetes, can be considered for ordinary coverage.

Medicare: weight-drug coverage routes ↗Ask if your plan pays for your reason for treatment
As of September 2026, a Medicare plan may cover the same medicine for an accepted non-weight use, such as diabetes, subject to its drug list and prior approval.
The plan still has to check your prescription before agreeing to pay.
Ask which health problem is written on your prescription and whether your plan accepts it.
From the record
A temporary Medicare route has separate terms
As of September 2026, the Medicare Bridge offers certain weight medicines to eligible members for $50 a month, from July 2026 through December 2027.
Record checked in September 2026.
CMS: the temporary Medicare Bridge ↗What Bridge checks about your health
As of September 2026, you must be at least 18 to use Bridge. It checks your body mass index, or BMI: a figure worked out from your weight and height.
The health checks use your details when this treatment began. You must meet one of these weight-and-health tests:
- BMI of 35 or more.
- BMI of 30 or more, with heart failure with normal pumping strength, uncontrolled high blood pressure, or long-term kidney disease at stage 3a or later.
- BMI of 27 or more, with pre-diabetes (blood sugar above normal), a previous heart attack or stroke, or artery disease with symptoms in the legs or arms.
For the blood-pressure test, the upper reading must be over 140 or the lower over 90, despite two blood-pressure medicines.
Bring your height, weight and health records. Ask the person prescribing to check the exact diagnosis, including any heart or kidney disease type or stage.
Check your drug plan and past payments too
As of September 2026, ordinary Medicare drug coverage, rather than Bridge, is the route for people who have type 2 diabetes.
Meeting a weight test alone does not qualify you; your diagnoses, drug-plan type and past payments matter too.
Ask the person prescribing to check the full Medicare Bridge list of health exclusions against your diagnoses.
You need drug coverage through a separate Part D plan or through an eligible Medicare Advantage plan.
Ask the plan which type it is and whether Bridge accepts that type.
GLP-1 is the name for a drug group that includes semaglutide and tirzepatide.
Your Medicare Part D plan's payment for a GLP-1 drug in 2026 rules out Bridge for all its medicines during 2026.
The recorded September 2026 rules had not yet set which past payments would count in 2027.
Bridge also requires a prescription, approval before payment and a continuing food and physical activity plan.
The Bridge payment does not count toward the plan's yearly spending cap, and coupons cannot be combined with it.
Ask the plan or person prescribing to check all the current Bridge rules for your case.
A savings card and a price without insurance are different
A copay is the part of an insurance-covered bill that you pay. A drug company's savings card can help pay that part.
As of September 2026, Medicare, Medicaid and military coverage are excluded from drug-company copay cards for these weight and diabetes medicines.
People with government insurance may still use a drug company's price for paying without insurance, under that offer's terms.
You pay the quoted medicine price yourself. Insurance pays no part of that bill; the payment adds nothing toward your plan's deductible or spending limit.
