Get an answer for your plan
GLP-1 medicines act like a hormone, a substance that carries messages in the body. This hormone helps control appetite and blood sugar.
The medicines a plan covers appear on a list called its formulary. Prior authorization is advance agreement from the plan to pay, required before the medicine is supplied.
- Is this medicine on my plan’s list for my diagnosed condition?
- Do you need approval before I get the medicine?
- What records does the prescriber need to send?
- What would my share of the bill be?
- Are the visit and tests billed through the plan or paid in cash?
As of September 2026, Medicaid coverage of GLP-1 medicines for obesity, a condition involving excess body fat, varies by state.
Ask your own plan for its current rules rather than relying on another person’s bill.
Medicare: the reason for treatment matters
Medicare Part D is its prescription drug benefit. As of September 2026, medicines solely for weight loss remain outside the basic benefit.
Another accepted use can make a medicine eligible for Part D payment, such as treating type 2 diabetes, which affects blood sugar.
Eligible does not mean your plan will pay. Your plan’s list of covered medicines and approval rules remain in effect.
What does the temporary Medicare Bridge cost?
As of September 2026, eligible people with Part D can get certain weight-loss medicines through the Medicare GLP-1 Bridge for a $50 copay per monthly supply.
A copay is your share of that medicine’s cost. The Bridge’s dates are July 1, 2026 for the start and December 31, 2027 for the end. It pays pharmacies separately from your usual Part D plan. In 2026, one service handles the Bridge’s approval requests and payments to pharmacies.
The $50 does not count towards the Part D deductible or its yearly limit on your own spending.
Before some plan benefits begin, a deductible is the amount you pay yourself.
The Bridge provides no added low-income subsidy, meaning help with that payment, and coupons cannot reduce it.
To qualify, you must meet rules about your weight and other health problems, your kind of Medicare plan and medicines the plan paid for before. The minimum age is 18 years old. Your prescriber must send a prescription and get approval from the Bridge before it will pay.
The Bridge excludes people with type 2 diabetes; their treatment uses ordinary Part D instead.
In 2026, the Bridge is unavailable if your Part D plan paid for a GLP-1 medicine earlier that year.
Only certain medicines and forms, such as particular pens or tablets, are included. Ask your clinician to check whether the exact product is included. Ask them to check every rule about who may use the Bridge too.
If you have a medical spending account
An HSA is a health savings account; an FSA is a flexible spending arrangement. Money for medical costs is set aside through these accounts.
As of September 2026, tax rules allow these accounts to pay for weight-loss care when it treats a specific disease a doctor has diagnosed. Care just to improve general health does not qualify.
Ask the account administrator what proof and receipts it needs before paying.
