Medicare clinical appeals about restrictions on a specific medication; distinct from the preserved Cigna-specific clinical-appeal route.

The page lists 844-374-7377 for clinical appeals during these hours. The linked redetermination form instead prints 800-935-6103 for expedited appeals and representative help; its separate route preserves that difference. Initial clinical reviews share this page phone but have different hours and intake destinations.

Completed Medicare drug-denial redetermination forms and supporting information under the current linked form.

Page 1 prints this phone for expedited appeal requests and help naming a representative. Page 2 prints the appeal fax and mailing recipient. The current parent page publishes a different clinical-appeals phone, 844-374-7377. Neither source is silently treated as superseding the other; no telephone hours are stated in the PDF.
