Short answer
A short-term, central-processor pathway for certain weight-management GLP-1 drugs.
CMS says the Medicare GLP-1 Bridge is a short-term demonstration running July 1, 2026 through December 31, 2027. It gives eligible Part D beneficiaries access to certain weight-management GLP-1 drugs through a single central processor that handles prior authorization, claims, and payment outside the Part D benefit. CMS says the Bridge uses a flat monthly copay, that the copay does not count toward the Part D out-of-pocket cap, and that no low-income subsidy applies.

What you actually came to find out
Plain answers first. Sources stay below for checking details.
When does it run?
CMS says July 1, 2026 through December 31, 2027.
Where does the script go?
To a single central processor, not the Part D plan.
What does it cost?
CMS says a flat monthly copay, outside the Part D cap.
Is it the BALANCE Model?
No. CMS says BALANCE is a separate, voluntary model.
Dates

Cost
Flat copay
CMS says a flat monthly copay applies and does not count toward the Part D cap.

The real point to grasp is that the Bridge runs alongside Part D, not inside it, which is why the prescription goes to a central processor rather than the drug plan.
Neutral landscape
The shape of the question
CMS is the main source because it defines the Bridge, its dates, and the central-processor design.
Source trail: CMS
The eligibility detail comes from the CMS prior authorization form, which sets the body-mass-index and lifestyle conditions.
Source trail: CMS
The routing matters because the same form sends diabetes, cardiovascular, sleep-apnea, and MASH cases to the Part D plan instead.

The BALANCE Model is the common point of confusion, and CMS describes it as a separate, voluntary model.

Medicare GLP-1 Bridge Prior Authorization Form
The CMS Bridge prior authorization form lists the Part D-eligible diagnoses that route to a Part D plan and the body-mass-index and lifestyle conditions for the Bridge.
Source framing
CMS says diagnoses like type 2 diabetes, cardiovascular risk reduction, obstructive sleep apnea, and MASH route to the Part D plan, while the Bridge covers weight management with body-mass-index and lifestyle conditions.

BALANCE Model
CMS describes the BALANCE Model, a voluntary innovation model for anti-obesity medications that is separate from the short-term GLP-1 Bridge.
Source framing
CMS says the BALANCE Model is a separate, voluntary innovation model, distinct from the short-term Medicare GLP-1 Bridge.

The forks people face
Most retirement questions hide a few smaller decisions. These are the practical pieces that change the plan.
Is your prescription for weight management or a medical diagnosis?
Why it matters: The Bridge covers weight management; diabetes, cardiovascular, sleep-apnea, and MASH go to Part D.
In real life: This fork decides whether the Bridge or Part D applies.
What to look at: What to look at: the CMS Bridge prior authorization form.
Did the prescription go to the central processor?
Why it matters: CMS says the Bridge runs outside Part D through a central processor.
In real life: This fork is the practical step that makes the Bridge work.
What to look at: What to look at: how your prescriber submits the Bridge request.
Are you mixing it up with the BALANCE Model?
Why it matters: The Bridge and the BALANCE Model are two different things.
In real life: This fork clears up the most common confusion.
What to look at: What to look at: the CMS BALANCE Model page.

How this page is curated
This page uses the CMS GLP-1 Bridge page, the CMS Bridge prior authorization form, and the CMS BALANCE Model page. It keeps the Bridge and the BALANCE Model separate because CMS governs them as two different programs.
