Humana Prior Authorization Phone Number: What Works
Humana prior authorization phone number depends on whether you're a member seeking medical/pharmacy preauthorization or a provider requesting PA-start with Humana's member preauthorization line 800-457-4708 (TTY: 711), and for faster coverage decisions use 866-737-5113.
Because prior authorization routes vary by product and state, use the phone number that matches your plan type (Medicare Advantage vs. other coverage) to avoid delays. Authorization routing is the difference between a 5-minute intake and a multi-day gap in approvals.
What to call for Humana prior authorization
Humana publishes a general medical/pharmacy preauthorization contact line for members, including expedited coverage decisions. Preauthorization intake is where you confirm what documentation the plan needs (and whether the request is medical, pharmacy, or both).
- Member medical/pharmacy preauthorization: 800-457-4708 (TTY: 711), 7 days a week, 8 a.m.-8 p.m. Eastern time.
- Expedited coverage decisions: 866-737-5113.
- Group Medicare plans: call the number on the back of your member ID card (TTY: 711); hours differ (Mon-Fri, 8 a.m.-9 p.m. Eastern time).
Phone numbers by request path
For some medication prior authorizations, Humana also lists a dedicated PA phone number (commonly used for Medicare-related medication authorization workflows). Medication prior auth is frequently handled through structured lists or ePA workflows rather than the same line used for medical preauthorization.
| Who is calling | What you're requesting | Phone number | TTY | Notes |
|---|---|---|---|---|
| Members | Medical or pharmacy preauthorization | 800-457-4708 | 711 | 7 days/week, 8 a.m.-8 p.m. Eastern time. |
| Members | Expedited coverage decisions | 866-737-5113 | - | Use when you need faster determination. |
| Providers/Medication PA workflow | Medication prior authorization (Medicare list workflow) | 866-461-7273 | 711 | Mon-Fri, 8 a.m.-11 p.m. Eastern time. |
Step-by-step: how to get approved faster
In intake calls, preparation reduces back-and-forth-plans typically need clinical details and the specific service/drug identifier to determine whether PA criteria are met. Clinical documentation is the quickest lever you control.
- Before calling, have the CPT/HCPCS code and/or drug name (and strength/form) ready for the PA request.
- If you have time-sensitive circumstances, ask for expedited coverage and use the expedited number when appropriate.
- If you're in a group Medicare plan, use the ID-card number instead of a generic line to ensure correct routing.
- Confirm what the plan needs to complete the request, then submit any required supporting clinical info promptly.
Practical benchmark: in many healthcare authorization workflows, the first complete submission can cut determination cycles by "days" versus incomplete calls-teams often target first-contact readiness within the first business hour of the request. (Use this as an operational goal, not a guaranteed outcome.)
