Humana denial appeals
Humana is among the top three Medicare Advantage carriers and also operates Tricare and a smaller commercial book. Medicare Advantage prior auth is the highest-volume denial category.
If Humana denied a claim or service, you can appeal, and the plan must give you its file and the criteria it used. Filing windows by plan type: 65 days from the notice (Medicare Advantage); 65 days from the notice (Part D); 90 days from the notice (TRICARE); at least 180 days (employer self-funded plans). The date printed on your denial notice controls; it can only be later than these floors, never earlier.
Humana appeals: the rule, the deadline and the next level, by plan type
Which row applies depends on the plan you hold, not on Humana's brand. Your ID card, the Summary Plan Description and the denial letter say which.
| Plan type | Rule that governs | File your appeal within | The plan must answer | If the plan says no again |
|---|---|---|---|---|
| Medicare Advantage (Part C) A private plan that replaces Original Medicare. The card says Medicare Advantage, HMO, PPO or PFFS. | 42 CFR Part 422, Subpart M (§§ 422.560 to 422.634). Coverage decisions must follow Original Medicare rules (42 CFR 422.101). | 65 calendar days from the date on the denial notice to request the plan's reconsideration (42 CFR 422.582, as amended effective 1 January 2025). | Expedited: 72 hours. Standard pre-service: 30 days (7 days for Part B drugs). Payment: 60 days (42 CFR 422.590). | If the plan does not fully reverse itself it must send the case to the Independent Review Entity on its own (42 CFR 422.592); then an ALJ hearing when the amount in controversy meets the annual threshold, the Medicare Appeals Council and federal court. State external review does not apply. |
| Medicare Part D (drug plan or MA-PD) A stand-alone drug plan or the drug benefit inside a Medicare Advantage plan. | 42 CFR Part 423, Subpart M; exceptions under 42 CFR 423.578. | 65 calendar days from the date on the notice to request a redetermination (42 CFR 423.582, as amended effective 1 January 2025). Formulary, tiering and step-therapy exceptions need the prescriber's supporting statement (§ 423.578). | Redetermination: 7 calendar days standard, 72 hours expedited (42 CFR 423.590). Coverage determinations: 72 hours standard, 24 hours expedited, once the prescriber's statement is received (§§ 423.568, 423.572). | Independent Review Entity reconsideration on your request within 65 days of the redetermination notice (§ 423.600); then ALJ, Council and court. |
| TRICARE Active-duty families, retirees and their families. Claims are handled by Humana Military (East) or TriWest (West) under the Defense Health Agency. | 32 CFR 199.10 (appeal and hearing procedures) and the TRICARE Operations Manual, Chapter 12. ERISA, the ACA appeal rules and state external review do not apply. | Reconsideration: 90 days from the date of the notice of the initial determination. Formal review by the Defense Health Agency: 60 days from the reconsideration decision. Hearing: 60 days from the formal-review decision (32 CFR 199.10). | Expedited review is available for pre-admission and pre-authorization denials; the contractor's clock for a standard reconsideration is stated in the letter. | Formal review by the DHA, an independent hearing when the amount in controversy meets the threshold in 32 CFR 199.10(d), and a final decision by the DHA Director. |
| Employer self-funded plan (ERISA) Most large employers. The employer pays the claims and hires the carrier to administer them; the Summary Plan Description says self-funded or self-insured. | ERISA § 503 (29 U.S.C. § 1133) and the claims-procedure rule, 29 CFR 2560.503-1. Federal external review under 45 CFR 147.136(d) for non-grandfathered plans. | At least 180 days from the adverse benefit determination (29 CFR 2560.503-1(h)(3)(i)). | Urgent care: 72 hours. Pre-service: 30 days. Post-service: 60 days (29 CFR 2560.503-1(i)(2)). | Federal external review by an accredited independent review organization, requested within 4 months of the final internal denial (45 CFR 147.136(d)); then a civil action under ERISA § 502(a). State insurance departments do not regulate self-funded plans; the U.S. Department of Labor does. |
What you can demand. The plan may not apply internal criteria that are more restrictive than Medicare's national and local coverage determinations, and must decide medical necessity on your individual circumstances (42 CFR 422.101(b), (c)). You can ask for the case file and the criteria used.
How to open the appeal. Cite 42 CFR 422.582 and 422.101(c): the plan must decide on your individual circumstances under Medicare coverage rules, and must forward an unfavorable reconsideration to the IRE itself.
What you can demand. The exception turns on the prescriber's statement that the formulary alternative would be less effective or would harm you (42 CFR 423.578(b)(5)).
How to open the appeal. Cite 42 CFR 423.578 and 423.582 and attach the prescriber's supporting statement written to the exception standard.
What you can demand. The sponsor, the beneficiary, a participating provider or an appointed representative can appeal. Ask the contractor for the file and the medical-necessity criteria it applied.
How to open the appeal. Cite 32 CFR 199.10 and the benefit rule in 32 CFR 199.4: state the appeal type, address it to the regional contractor named on the letter, and request the criteria used.
What you can demand. The plan must give you the claim file, the internal rule or criterion it relied on, and the identity of the reviewer, free of charge, on request (29 CFR 2560.503-1(h)(2)(iii), (m)(8)).
How to open the appeal. Cite ERISA § 503 and 29 CFR 2560.503-1 in the opening paragraph: request the claim file and the specific criteria relied on, and note the 30-day (pre-service), 60-day (post-service) and 72-hour (urgent) decision clocks.

Patterns we see on Humana denials
Five-level Medicare appeal process
Humana Medicare Advantage denials enter the federal appeal ladder: plan reconsideration → IRE (Maximus) → ALJ → Medicare Appeals Council → federal court. Federal data show Medicare Advantage plans overturn a large share of denials once they are appealed, yet very few members appeal; reversal odds stay meaningful through the IRE and ALJ levels.
DME (durable medical equipment) denials
Humana DME denials often cite missing home-evaluation documentation. Re-filing with the home-evaluation packet attached is the most common reversal path.
Skilled nursing and post-acute care
Humana has been the subject of CMS audits on early termination of skilled nursing coverage. Appeals citing CMS coverage manual standards have a documented success record.
Medicare Advantage federal 5-level ladder. Commercial: internal then external review.
Medicare Advantage: 65 days from the notice for plan reconsideration, automatic forwarding to the IRE, then 60 days for each later level. Commercial: 180 days from denial for internal; generally at least 4 months (120 days) for federal external review (varies by plan and state).
