CMS BALANCE Model Prep: Key GLP-1 Bridge Demonstration Insights for Medicare Health Plans

CMS is introducing a major shift in how Medicare approaches obesity and metabolic health through the Better Approaches to Lifestyle and Nutrition for Comprehensive Health (BALANCE) Model.

CMS is introducing a major shift in how Medicare approaches obesity and metabolic health through the Better Approaches to Lifestyle and Nutrition for Comprehensive Health (BALANCE) Model.


The initiative expands access to GLP-1 medications for weight loss while emphasizing lifestyle modification and long-term health outcomes.


To prepare for the model, CMS will launch a Medicare GLP-1 Bridge demonstration in July 2026, providing early access to certain GLP-1 therapies before the BALANCE Model begins in 2027.


While the bridge program will be administered outside the traditional Part D benefit structure, health plans should begin preparing now for the operational and clinical implications that will follow.


Why the BALANCE Model Matters

The BALANCE Model introduces several important changes for Medicare Advantage and Part D plans:

  • Expanded access to GLP-1 therapies for weight loss (e.g. Wegovy and Zepbound) for eligible beneficiaries

  • New clinical criteria and prior authorization requirements

  • Integration of medication therapy with lifestyle interventions

  • Greater focus on long-term outcomes and population health management


These changes will require thoughtful coordination across clinical, pharmacy, and operational teams.


GLP-1 Bridge Main Takeaways for Health Plans:

  • Zero financial risk – The Bridge operates outside of the Part D benefit. CMS will use a central processor for claims and payments. Claims will not count towards True Out-of-Pocket (TrOOP) costs.

  • Fixed Beneficiary Cost – Eligible members will pay a flat $50 copay.

  • Automatic Participation – No action is required by health plans to participate. Members that meet the clinical criteria are eligible.

  • Technical Instructions – CMS has indicated the payer sheet is forth coming. Plans should work with their PBM or pharmacy network management teams to educate on the specific BIN/PCN for Bridge.

  • Member Service Training – Members service representatives should be trained to answer questions on the Bridge to appropriately direct members to either the health plan or the GLP-1 Bridge, as required based on the member’s individual needs.


What Health Plans Should Be Doing Now

While CMS is handling the adjudication, Plans must ensure a smooth member experience and understanding of the 2027 transition to the BALANCE Model.


Plan should be preparing by focusing on:

  1. Messaging and Provider Portals: Provider should be educated to direct GLP-1 use for weight loss to the GLP-1 Bridge. To avoid prior authorization (PA) requests for weight loss only indications and subsequent denials, CMS is encouraging sponsors to return messaging directing to the central processor. Plans should work internally and with vendors to educate providers and create automated messaging at key workflow points. CMS stated additional information on PA will be available in the Spring.

  2. Align Clinical Strategies. The Bridge only covers GLP-1s for weight loss. If a GLP-1 is prescribed for a Part D-covered indication, it remains the plan’s responsibility. Ensure your clinical review teams are trained to properly decision PA and exception cases and denial language for notifications.

  3. Prepare for the BALANCE Model Transition. The Bridge ends on December 31, 2026. To maintain access in 2027, members must be enrolled in a plan that has opted into the BALANCE Model. Plans should already be working with their actuaries to determine participation in preparation for the bid submission. CMS is exploring sharing Bridge utilization. Plan should be monitoring data to understand current and potential member utilization for their targeted service areas. Plan must apply and be approved to participate in the BALANCE Model.
