Step-by-Step: Appeal Your Anthem Denial in Maryland

Step 1: Decode the Denial

Maryland law requires Anthem to provide a specific clinical rationale, cite the policy provision, and explain your appeal rights. Request the complete claims file — including IndiGO review notes and the Clinical Policy Bulletin — immediately upon receiving the denial.

Deadline: 180 days from the denial date.

Step 2: Get Your Physician's Support

Your doctor's letter of medical necessity is the most important element of your appeal. The letter should directly rebut Anthem's stated denial reason, address each criterion in the Clinical Policy Bulletin, and cite peer-reviewed evidence. For mental health denials, the letter should also address how Anthem's criteria compare to those applied to analogous physical health conditions.

Step 3: Write a Targeted Appeal Letter

Your appeal letter must:

• State your Anthem member ID, claim number, and denial date
• Quote Anthem's exact denial language
• Address each Clinical Policy Bulletin criterion point-by-point
• Cite peer-reviewed studies and specialty guidelines
• Reference Md. Insurance Code § 15-10A-01 (Maryland External Review Law) and applicable ACA rights
• For mental health denials, invoke MHPAEA and Maryland's parity enforcement authority
• Attach all supporting documentation

Step 4: Submit Through Anthem's Portal

File through the Anthem member portal at anthem.com or the Sydney Health app. Send a certified mail copy as a legal backup. Anthem must respond within 30 days for standard appeals and 72 hours for urgent/expedited cases.

Step 5: Escalate If Needed

If the internal appeal is denied:

• External review — File under Md. Insurance Code § 15-10A-01 through the Maryland Insurance Administration at insurance.maryland.gov. An IRO physician reviews your case. Decision is binding on Anthem.
• Peer-to-peer review — Your doctor speaks directly with Anthem's medical director about the clinical specifics.
• Regulatory complaint — File with the Maryland Insurance Administration at (410) 468-2000. Maryland's MIA has strong enforcement authority and actively investigates insurer practices.
• Legal action — For high-value claims, consult an insurance attorney about Maryland bad-faith laws.

Challenging Anthem's Medical Necessity in Maryland

Maryland's external review process requires IROs to evaluate appeals against evidence-based standards. When Anthem denies based on "not medically necessary," obtain the Clinical Policy Bulletin and build a point-by-point rebuttal addressing each criterion with your medical records and physician's testimony. For mental health denials specifically, Maryland's MIA has dedicated parity enforcement resources — request a parity analysis as part of your complaint if Anthem applied stricter criteria to your behavioral health claim than it would apply to an analogous physical health condition.
