Which route should I use?

1. Use this fax only when you're requesting an expedited (fast-tracked) coverage decision, not a routine claim.
2. Anyone acting on the member's behalf, a family member, caregiver, or doctor, can submit on this same number.
3. Include a clear statement of urgency and the reason expedited review is needed, Humana's expedited process depends on that being clear upfront.

Documents to include

State the specific service or medication under review, the reason for urgency, and the member's Humana ID number. Humana's page describing this process has the full requirements.
