How to Appeal a Denied Insurance Claim in North Carolina

Step 1: Obtain and Review Your Denial Letter

Your insurer must provide a written denial stating the specific reason for denial, the clinical criteria used, and your appeal rights. Review it carefully. Note the internal appeal deadline — North Carolina generally allows 180 days from the date of denial to file an internal appeal, though your specific plan may have a shorter window.

Step 2: Identify Your Plan Type

Determine whether your plan is fully insured (regulated by NCDOI) or self-funded (governed by ERISA). Your employer's HR department or your Summary Plan Description (SPD) will confirm this. Fully insured plan members have access to all North Carolina consumer protections. ERISA plan members retain federal appeal rights, including the right to external review under the ACA.

Step 3: File Your Internal Appeal in Writing

Submit your appeal in writing before the deadline. Include your physician's letter of medical necessity, relevant medical records, clinical guidelines supporting the denied treatment, and a written statement addressing the specific reason cited in the denial. Send by certified mail or via the insurer's secure portal with confirmation. Under ACA rules, the insurer must acknowledge receipt and decide within 30 days (non-urgent) or 72 hours (expedited).

Step 4: Cite Applicable Clinical Guidelines

Reference authoritative guidelines that support your treatment. NCCN guidelines for oncology, AHA/ACC for cardiac conditions, ADA for diabetes, APA for mental health, and ASMBS for bariatric surgery are recognized by North Carolina regulators and courts. Citing these guidelines directly in your appeal letter strengthens the medical necessity argument.

Step 5: File a Complaint with the NCDOI

File a consumer complaint with the North Carolina Department of Insurance at www.ncdoi.gov or by calling 855-408-1212. NCDOI investigates potential violations of North Carolina insurance law and can require insurers to respond and justify their decisions. Filing a complaint concurrently with your internal appeal creates regulatory pressure and a documented record.

Step 6: Request Independent External Review

Stat. § 58-50-75 through § 58-50-95) provides the right to independent external review by a CMS-approved IROs) Explained" class="auto-link">Independent Review Organization (IRO).
