How to Appeal a Anthem Denial

What should I emphasize in a Anthem appeal?

Anthem imaging denials are frequently Carelon criteria cases. Winning appeals usually include a timed history of conservative care plus specific exam findings that map to the cited appropriateness criteria. Name your state Anthem plan correctly on every page of the packet.

How do I appeal a Anthem denial step by step?

1. Step 1

   Confirm your state Anthem plan name from your ID card because portals, addresses, and policies differ by region.

2. Step 2

   Request the written denial with claim number, reason code, and any Carelon/AIM reference for imaging or specialty reviews.

3. Step 3

   Download or request the clinical guidelines or medical policy Anthem or Carelon applied to your case.

4. Step 4

   Have your specialist document failed conservative care, red-flag symptoms, and exam findings that support the denied service.

5. Step 5

   Draft an internal appeal that quotes the cited criteria and maps your records to each requirement.

6. Step 6

   Submit through anthem.com or certified mail to the appeals address on your EOB before the printed deadline.

7. Step 7

   Request expedited review when delay could seriously jeopardize life, health, or ability to regain maximum function.

8. Step 8

   If internal appeals are exhausted, pursue external review through your state insurance department or federal HHS process when eligible.

What documents do I need for a Anthem appeal?

• Anthem denial letter and claim number
• Carelon or AIM authorization reference if imaging was involved
• Specialty clinical notes and exam findings
• Conservative therapy documentation (PT, injections, medications)
• ACR Appropriateness Criteria or specialty society guidelines
• Prior authorization request and Anthem/Carelon response
• Imaging reports supporting medical necessity
• Proof of timely filing (portal screenshot or certified-mail receipt)

What laws can I cite in a Anthem appeal?

Citing the correct framework shows reviewers you understand your rights. Exact applicability depends on whether your Anthem coverage is employer self-funded, fully insured, Medicare Advantage, or Medicaid.

• ERISA §503 (29 U.S.C. §1133): employer-sponsored Anthem plans
• ACA Section 2719 (42 U.S.C. §300gg-19): internal and external review for non-grandfathered plans
• State insurance external review statutes: fully insured Anthem products
• 42 CFR Part 422: Anthem Medicare Advantage appeals

What if Anthem denies my appeal?

If your first-level Anthem appeal is upheld, review your denial letter for the next appeal level and filing deadline. Depending on your plan type, you may request a second internal review, external review by an Independent Review Organization under ACA Section 2719, a Medicare Independent Review Entity, a state fair hearing for Medicaid, or state Independent Medical Review for HMO coverage. Deadlines and available paths are printed on your adverse decision notice.
