Combination use with another targeted weight loss agent
Plans without specific benefit language allowing weight loss drug coverage

Policy note: OSA pathway allows a lower BMI threshold of >= 27 kg/m2 (without a separate comorbidity requirement) when requesting for the primary indication of OSA. AHI severity threshold is not specified in this policy. No PAP/CPAP prior trial is required per this policy. The OSA indication is handled within the same section IX as weight loss; both pathways share the same approval durations and continuation criteria. The moderate-to-severe AHI criterion from FDA labeling is not explicitly reproduced in the PA criteria. The T2DM exclusion applies here as the policy states 'Requests for Wegovy or Zepbound for patients with type 2 diabetes mellitus as a comorbid, weight-related condition are excluded from coverage.'
