Bridge or Part D — which route does your request take?
Starting July 1, 2026, a GLP-1 request can travel one of two roads: the new Bridge program, or your regular Part D plan. Send it down the wrong one and you get a denied claim and weeks of delay. The good news: the routing rules are knowable in advance.
What sends a request through Part D
- Type 2 diabetes — GLP-1s for diabetes are regular Part D territory.
- Moderate-to-severe sleep apnea — note the severity: mild sleep apnea is not an exclusion.
- MASH (metabolic dysfunction-associated steatohepatitis, a form of fatty liver disease).
- A GLP-1 previously received through your Part D plan — once your plan has paid for a GLP-1, future requests go to the plan. Cash purchases through LillyDirect, NovoCare, or compounding pharmacies don't count.
- A different indication — for example, Wegovy prescribed to reduce cardiovascular risk.
Everything else — weight reduction and maintenance for people meeting the BMI pathways — is Bridge territory.
Routing isn't rejection
Being routed to Part D doesn't mean no medication. It means your clinician submits the request to your plan, under your plan's rules, rather than to the Bridge. For someone with type 2 diabetes, that's often the better-established path anyway. The point of knowing your route in advance is avoiding the ping-pong: claim sent to the wrong place, denied, resubmitted, weeks lost.
The mechanics: why the prescription needs special words
The Bridge runs on its own claims processor, separate from your plan. CMS instructs prescribers to put an obesity diagnosis code (E66 family) on the prescription and write "SEND TO BRIDGE FOR WEIGHT MANAGEMENT" in the note field. Without that, the pharmacy defaults to billing your Part D plan — which will likely reject a weight-loss GLP-1, since that's the very gap the Bridge exists to fill. This is the single most practical thing to hand your doctor; it's on the clinician page of our request packet.
When the answer is genuinely unclear
Mixed situations are real: prediabetes that might be diabetes by now, a sleep study you never followed up on, a Wegovy conversation that's partly about heart health. When our screener says "unclear — clinician review needed," that's not a hedge; it means your chart holds the answer and your doctor is the person to read it. The generated message tells them exactly what to check.
Frequently asked questions
Is being routed to Part D bad news?
Not necessarily — it's a different path, not a closed door. Your clinician submits to your plan instead of the Bridge.
Why does the pharmacy need special instructions?
The Bridge has its own claims processor. The E66 code and "SEND TO BRIDGE" note tell the pharmacy where to send the claim.
Does mild sleep apnea route me to Part D?
No — the published exclusion is moderate-to-severe sleep apnea only.
