Completed Medicare drug coverage-determination requests under the current linked form, not clinical appeals or member payments.

The current official Medicare coverage page links this form. Page 1 still prints 800-935-6103; page 3 prints fax 877-251-5896 and the Medicare Reviews address. The parent page instead lists 844-374-7377 for initial clinical coverage reviews. Both published telephone routes are preserved with their source-specific scope; no supersession is inferred. The old fax 877-328-9799 is not confirmed by these current sources. PDF metadata is December 2025, not a declared effective date.
