Information for Providers

The Medicare GLP-1 Bridge is a short-term demonstration run by CMS that will provide eligible Medicare Part D beneficiaries with access to certain GLP-1 drugs between July 1, 2026, and December 31, 2027.

The Medicare GLP-1 Bridge will operate outside of the Medicare Part D benefit’s coverage and payment flow. As a result, Part D sponsors will not carry risk for eligible GLP-1 drugs furnished under the Medicare GLP-1 Bridge, and Part D sponsors do not have to opt in to the Medicare GLP-1 Bridge for eligible beneficiaries to access these drugs beginning July 1, 2026. In 2026, CMS will use a single central processor to manage prior authorization, claims adjudication, and payment to pharmacies for the Medicare GLP-1 Bridge.

The Medicare GLP-1 Bridge will be extended through December 31, 2027, providing eligible Medicare Part D beneficiaries with access to certain GLP-1 drugs and allowing CMS to collect additional data on GLP-1 utilization to share with Part D plan sponsors ahead of potential implementation of BALANCE in Part D. 

Only Medicare Part D beneficiaries who are enrolled in eligible plan types,  use GLP-1s to reduce excess body weight and maintain weight reduction, and meet the Medicare GLP-1 Bridge Clinical Criteria (see FAQ “What clinical criteria must a beneficiary meet in order to qualify for the Medicare GLP-1 Bridge?”) will be eligible for coverage under the Medicare GLP-1 Bridge. 

Eligible plan types: To qualify for coverage of eligible GLP-1 drugs via the Medicare GLP-1 Bridge, Medicare beneficiaries must be enrolled in a standalone prescription drug plan (PDP) or Medicare Advantage (MA) coordinated care plan (i.e., HMO, HMOPOS, and Local and Regional PPO plans) that offers prescription drug coverage (MA-PD plans) in CY 2026.Part D beneficiaries in Special Needs Plans (SNPs), employer/union group waiver plans (EGWPs), and the Limited Income Newly Eligible Transition (LI NET) program are eligible to participate. Beneficiaries enrolled in private fee-for-service plans, section 1876 cost contract plans, section 1833 health care prepayment plans, PACE organizations, fallback plans, and religious fraternal benefit plans are not eligible to participate, unless also enrolled in a standalone PDP, as applicable. Additionally, dually-eligible beneficiaries who are enrolled in eligible Part D plan types and meet the prior authorization criteria will have access to GLP-1 drugs via the Medicare GLP-1 Bridge.

Please note that the Medicare GLP-1 Bridge is a Section 402 demonstration and does not constitute a Medicare Part D plan offering prescription drug coverage. Beneficiaries in need of prescription drug coverage should contact 1-800-MEDICARE (1-800-633-4227) or their local State Health Insurance Assistance Program (SHIP). 

At this time, for the purposes of the Medicare GLP-1 Bridge, an eligible GLP-1 drug is any of the following products when used to reduce excess body weight and maintain weight reduction: Foundayo®, Wegovy® (injection and tablets), and Zepbound® (KwikPen®). 

Note: This was updated on April 6, 2026, to include Foundayo® following FDA approval and to clarify that only the KwikPen®  formulation of Zepbound® is included.

Beginning July 1, 2026, all formulations of Foundayo®, all formulations of Wegovy®, and the KwikPen ® formulation of Zepbound® will be available to eligible beneficiaries through the Medicare GLP-1 Bridge. The single-dose vial and single-dose pen formulations of Zepbound® will not be available through the Medicare GLP-1 Bridge.

To access GLP-1 medications via the Medicare GLP-1 Bridge, an eligible beneficiary must have a medical provider submit a prior authorization request and a prescription for an eligible GLP-1 drug for a use covered under the demonstration. Prior authorization requests will be accepted electronically or by fax using the Medicare GLP-1 Bridge prior authorization form. CMS strongly encourages providers to submit prior authorization electronically. 

Providers do not need to take any action at this time. CMS will provide additional information on prior authorization processes in June 2026, including the Medicare GLP-1 Bridge prior authorization fax form, on the CMS webpage for the Medicare GLP-1 Bridge. Prior authorization requests will not be accepted or processed before July 1, 2026, at which point a provider may submit a prescription to a pharmacy and will receive a request to complete prior authorization.

Additional information on how to submit a prior authorization request will be available on the CMS webpage for the Medicare GLP-1 Bridge in June 2026. Prior authorization requests will not be accepted or processed before July 1, 2026. 

For the Medicare GLP-1 Bridge, as in the Part D program, a provider does not need to be enrolled in Medicare in order to write a prescription or submit a prior authorization request for products provided under the Medicare GLP-1 Bridge to an eligible beneficiary. However, the provider must not be on the Preclusion List in order for the drug to be coverable under the Medicare GLP-1 Bridge for an eligible beneficiary.

For a beneficiary to qualify for the Medicare GLP-1 Bridge, a provider must submit a prior authorization request that attests the beneficiary meets the following criteria:

• The beneficiary is prescribed the requested drug to reduce excess body weight and maintain weight reduction in combination with current and ongoing lifestyle modification including structured nutrition and physical activity consistent with the applicable FDA approved label, AND
  • The beneficiary is at least eighteen (18) years of age and has a BMI greater than or equal to thirty-five (≥35) at the time of initiation of GLP-1 therapy, or
  • The beneficiary is at least eighteen (18) years of age and has a BMI greater than or equal to thirty (≥30) at the time of initiating GLP-1 therapy with a diagnosis of one or more of the following: (A) heart failure with preserved ejection fraction, (B) uncontrolled hypertension (defined as systolic blood pressure above 140 mm Hg or diastolic blood pressure above 90 mm Hg, despite concurrent treatment with two antihypertensive medications), or (C) chronic kidney disease stage 3a or above, or
  • The beneficiary is at least eighteen (18) years of age and has a BMI greater than or equal to twenty-seven (≥27) at the time of initiating GLP-1 therapy with a diagnosis of one or more of the following: (A) pre-diabetes (as defined by American Diabetes Association guidelines), (B) previous myocardial infarction, (C) previous stroke, or (D) symptomatic peripheral artery disease.

The Medicare GLP-1 Bridge was designed to increase access to GLP-1s for beneficiaries who seek the drug solely to reduce excess body weight or maintain weight reduction. Type 2 diabetes, obstructive sleep apnea, and noncirrhotic metabolic dysfunction-associated steatohepatitis (MASH) indications are eligible for Part D coverage. Beneficiaries with these diagnoses are eligible to receive GLP-1s through their Part D plan and therefore are ineligible to receive them through the Medicare GLP-1 Bridge, even if they otherwise meet the Medicare GLP-1 Bridge clinical criteria. Eligible GLP-1s are only furnished under the Medicare GLP-1 Bridge, with the $50 co-pay, when prescribed for a weight management indication. If a Medicare Part D beneficiary has a prescription for a GLP-1 drug for an indication covered under Medicare Part D, they should continue to obtain their GLP-1 through their Part D plan. 

Eligible beneficiaries must meet the clinical criteria at the time of GLP-1 therapy initiation. This includes beneficiaries who initiated therapy prior to enrolling in Medicare Part D and/or prior to the July 1, 2026 launch of the Medicare GLP-1 Bridge. 

For example, if a beneficiary initiated GLP-1 therapy in September 2024 with a body mass index (BMI) of 37 and has a BMI of 34 at the time of a July 2026 prior authorization request, the prescribing provider should attest that the beneficiary met the BMI ≥35 criterion at the time therapy was initiated.

If a Medicare Part D beneficiary has a prescription for a GLP-1 drug for an indication covered under Medicare Part D, they should continue to obtain their GLP-1 through their Part D plan.
