Why Zepbound requests get denied by Oregon Medicaid

Based on what this policy asks for. Fix these before the first submission.

Your plan's benefit excludes weight loss medications. A prior authorization cannot override a benefit exclusion — ask about a formulary exception or a different covered pathway.
Wrong brand for the diagnosis. Zepbound and Mounjaro are the same molecule with different approved uses; a request for Zepbound under a diagnosis that matches Mounjaro is routinely denied.
Diagnosis code missing or wrong on the request.
BMI not documented in the chart notes (or documented without a baseline weight and date).
No documented diet and exercise program.

If weight loss isn't covered on your plan

Oregon Medicaid has separate Zepbound policies that don't depend on the weight loss benefit:

Osa — covered on Medicaid.
