• Network disputes: North Charleston has a mix of health system affiliates and independent providers. Some facilities accept certain plans while their affiliated physicians do not, creating surprise out-of-network charges.
• Medical necessity denials: Insurers use clinical guidelines to evaluate whether a procedure or treatment was necessary. If your claim doesn't match their criteria — even with physician documentation — it may be denied.

Step-by-Step: Filing Your Appeal

1. Gather your denial documentation. Your denial letter and EOB)" class="auto-link">Explanation of Benefits (EOB) are the starting points. The EOB shows what was billed, what was allowed, and what was denied — and the denial letter explains why.

2. Request the insurer's clinical criteria. BCBS SC, Humana, and other carriers use specific clinical guidelines (often from InterQual or MCG) to determine medical necessity. You are entitled to request a copy of the criteria used in your denial.

3. Work with your provider. Ask your treating physician to write a letter of medical necessity that directly addresses the insurer's stated reason for denial. Clinical notes, test results, and specialist letters all strengthen your case.

4. Write your appeal letter. Respond to each denial reason with specific evidence. Be concise, factual, and reference your plan's coverage documents where applicable.

5. Submit before the deadline. Internal appeal deadlines are printed on your denial letter — typically 180 days for non-urgent appeals. Don't miss it.

6. Go external if needed. If your insurer upholds the denial, request an IRO review within four months of the final internal decision.

Mistakes That Can Cost You

Many North Charleston residents lose winnable appeals by:

• Not appealing at all after receiving a denial notice
• Missing the deadline because they waited for the provider to act
• Submitting a letter without physician documentation
• Accepting a denial for an experimental treatment without checking whether peer-reviewed evidence supports coverage
