Step-by-Step: How to Appeal Your Anthem Denial in South Dakota

Step 1: Understand the Denial

Read your Anthem denial letter carefully. It must state the specific reason for denial, the plan provision or clinical criteria applied, and your appeal rights. Request the complete claims file, including the Clinical Policy Bulletin and reviewer's notes. You are entitled to this under federal law.

Step 2: Build Your Evidence

Your physician's letter of medical necessity is the foundation of your appeal. It should address each of Anthem's denial criteria point by point, cite clinical guidelines accepted in South Dakota and nationally, and explain why the treatment is appropriate for your specific clinical situation. For rural out-of-network disputes, document the absence of accessible in-network specialists.

Step 3: Write Your Appeal Letter

Your appeal letter should:

• Open with your Anthem member ID, claim number, denial date, and treatment denied
• Quote Anthem's exact denial language and address each point with documented evidence
• Cite South Dakota Code §58-17H and applicable South Dakota insurance statutes
• Invoke MHPAEA §1185a if mental health or substance use disorder benefits are at issue
• Reference applicable federal law (ACA, ERISA, No Surprises Act)
• Attach physician letter and supporting clinical documentation
• For out-of-network disputes: document network adequacy failure with specifics about unavailable in-network providers
• State your intent to request South Dakota Division of Insurance external review if the denial is upheld

Step 4: Submit and Track

Send via certified mail to the Anthem Appeals Department address on your denial letter, and also submit through the Anthem member portal. Keep all records. Calendar Anthem's response deadline.

Step 5: Escalate If Needed

If Anthem upholds the internal appeal:

• South Dakota Division of Insurance External Review — File at dlr.sd.gov/insurance/ or call (605) 773-3563. An IRO reviews your case at no cost; the decision binds Anthem.
