Ask for the whole bill.

Does insurance pay?

Ask the insurance plan about the proposed product by name and the health condition it is meant to treat. Request the answer in writing if possible.

Medicare drug-plan coverage was possible as of September 26, 2026 for two uses: treating type 2 diabetes with Mounjaro, or treating moderate to severe obstructive sleep apnea with Zepbound when obesity is also present.

With obstructive sleep apnea, a blocked airway causes repeated pauses or shallow breathing while asleep.

Coverage is possible, but not promised. The medicine must be on the plan’s list, and the plan must approve the request before it pays.

Ask separately about Medicare’s weight programme.

CMS, the agency running Medicare, describes its temporary Medicare GLP-1 Bridge as a route for people who meet its rules and have Part D, Medicare’s prescription-drug coverage.

GLP-1 is the name of a hormone, a chemical message from the gut that helps control hunger and blood sugar. The programme name refers to medicines that act like this message.

As of September 26, 2026, the programme included only the Zepbound KwikPen for tirzepatide; single-dose pens and vials were excluded.

CMS’s terms checked September 26, 2026 require a prescription, approval before payment and a qualifying Medicare drug plan. You must be at least 18. The age and health rules are judged from when treatment with these medicines began.

The weight rules use BMI. This number is worked out from your height and weight. Ask the prescriber to calculate it and see which of these routes fits:

• BMI at or above 35.
• BMI of 30 or more, plus one of these: a type of heart failure called heart failure with preserved ejection fraction; high blood pressure above the limits below despite two medicines for it; or kidney disease graded stage 3a or later.
• BMI of 27 or more, with one of these: pre-diabetes, when blood sugar is higher than normal without reaching the diabetes range; a past heart attack or stroke; or symptoms from narrowed arteries, the blood vessels carrying blood to the arms or legs.

For the blood-pressure route, CMS sets the limit above 140 for the top reading or above 90 for the bottom reading, measured in mm Hg, the usual blood-pressure unit. The pressure must remain above that limit despite two blood-pressure medicines.

Ask whether your heart diagnosis or kidney results match the exact medical terms in these rules. Weight alone does not tell everyone whether they qualify.

CMS also requires ongoing changes to food and activity. You cannot use the 2026 Bridge if your GLP-1 medicine was paid for by Part D during 2026. As of September 26, 2026, CMS had not set the earlier-use rule for 2027.

Under CMS’s terms checked September 26, 2026, ordinary Part D is the route for people with type 2 diabetes. It is also the route for people with obstructive sleep apnea that is moderate to severe.

This also applies to a liver illness called MASH when there is moderate to advanced liver scarring but no cirrhosis, meaning severe lasting liver scarring. A fatty liver diagnosis by itself does not always exclude someone from the Bridge. A prescription to lower the risk of serious heart or blood-vessel problems also goes through ordinary Part D.

Ask the prescriber to check those diagnoses in your health record. Ask your drug plan whether your type of plan allows the Bridge.

The yearly Part D cap limits what you pay for medicines covered through ordinary Part D, rather than the whole medicine bill. That limit is $2,100 in 2026 and $2,400 in 2027.

Once your counted payments reach that limit, you owe no more for those covered Part D medicines for the rest of that year. CMS says none of your $50 Bridge payment counts toward the limit. Medicare’s extra help with drug costs for people on low incomes does not reduce that payment.

Ask your plan which payments count toward your yearly limit and what it pays once you reach that limit. Keep the Bridge payment separate when checking the answer.

A savings card is another question.

The maker’s savings-card rules checked September 26, 2026 require insurance from a private plan or workplace. People with Medicare, Medicaid or military coverage are excluded.

Being excluded from a savings card does not automatically exclude someone from a maker’s cash price.
