Information for Pharmacies

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 nationwide and available in all states and territories.

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. The specific National Drug Code (NDCs) are listed below:  

• Foundayo® NDCs: 0002-4178-31, 0002-4503-31, 0002-4794-31, 0002-4803-31, 0002-4839-31, 0002-4953-31

This list of products and NDCs may be updated over the course of the Medicare GLP-1 Bridge.  

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, moderate to severe 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. 

Medicare GLP-1 Bridge prior authorization approvals are valid through December 31, 2027. After the first fill is approved, subsequent fills won’t need a new prior authorization, unless the patient switches from one covered GLP-1 drug to a different one. 

CMS will be utilizing Humana, the current administrator of the Limited Income Newly Eligible Transition (LI NET) program, as the central processor for the Medicare GLP-1 Bridge. The LI NET infrastructure provides the end-to-end operational capabilities and national scale that are critical to provide broad access to GLP-1 drugs to Medicare beneficiaries via the Medicare GLP-1 Bridge starting July 1, 2026.

The Medicare GLP-1 Bridge will be the primary payer for products covered under the Medicare GLP-1 Bridge and will not coordinate benefits with other payers. Coupons and discount programs may not be applied to Medicare GLP-1 Bridge claims. 

The central processor will process claims submitted electronically using the NCPDP Telecommunication Standard. Paper claims and direct member reimbursements will not be accepted by the central processor. 

CMS expects to release additional operational guidance on pharmacy claims processing in Spring 2026.

Pharmacies do not need to opt-in to participate in the Medicare GLP-1 Bridge. CMS and the central processor will provide additional technical instructions on pharmacy claims processes for the Medicare GLP-1 Bridge in the coming months.

CMS has established a Bank Identification Number (BIN) and Processor Control Number (PCN) that is specific to the Medicare GLP-1 Bridge (028918 MEDDGLP1BR). Please reference the payer sheet for more information. CMS will conduct outreach and education to help pharmacists understand when to submit a claim request for an eligible GLP-1 drug to the beneficiary’s plan versus the central processor.

No. If a prescriber has determined that their patient might be eligible for coverage under Medicare GLP-1 Bridge, they may direct the pharmacist to send the claim directly to Medicare GLP-1 Bridge.  

The pharmacy will need the beneficiary’s MBI, or Medicare Number, to submit a claim to the central processor for an eligible GLP-1 drug. If the beneficiary does not have their Medicare card, a pharmacy may ask a beneficiary to provide their Medicare card or the last 4 digits of their Social Security number to look up the Medicare Number via an E1 transaction. 

Pharmacies will collect a $50 copay amount from the eligible beneficiary, and the central processor will process payment to the pharmacy. Pharmacies will be reimbursed by the central processor at the wholesale acquisition cost of a drug, less the beneficiary copay, plus a dispensing fee and, as applicable, sales tax.
Note: This was updated on March 9, 2026 to clarify that the wholesale acquisition cost will be the standard reimbursement amount to pharmacies for products dispensed through the Medicare GLP-1 Bridge.

The CMS central processor will pay a dispensing fee of $3 for each Medicare GLP-1 Bridge claim ($5 for a beneficiary residing in long-term care). 

Eligible beneficiaries will have a $50 copay. Eligible GLP-1 drugs furnished under the Medicare GLP-1 Bridge are provided outside of the Part D benefit payment flow and coverage. This means that the Part D deductible will not apply, no part of the $50 copay counts towards the beneficiary’s TrOOP costs, and there is no low-income subsidy (LIS) provided for LIS beneficiaries. 

Beneficiaries who are approved for coverage under the Medicare GLP-1 Bridge may obtain a single monthly supply (28 or 30 days) of an eligible GLP-1 product per fill. Sixty or ninety-day fills are not available under the Medicare GLP-1 Bridge. Transition fills providing less than a single monthly supply (28 or 30 days) are also not available under the Medicare GLP-1 Bridge.  

The Medicare GLP-1 Bridge Pharmacy Help Desk is available at 844-673-0910. Representatives are available to assist pharmacies with questions about the claims submission process or the status of a submitted claim.  

Pharmacies can also find additional information in the Pharmacy Fact Sheet which includes an overview of the process and key details about the Medicare GLP-1 Bridge for pharmacies. CMS has also released a Pharmacy Reject Code Reference Tool to assist pharmacies.
