What to Ask Your Doctor or Provider

Your provider plays a key role in your appeal. Ask them for:

• →A Letter of Medical Necessity that directly rebuts each criterion cited in the denial letter
• →Clinical notes documenting your specific condition, severity, and functional limitations
• →Documentation of all prior treatments tried and why they failed or are contraindicated
• →Reference to any published guidelines that support the treatment for your diagnosis
• →A statement of what harm may result from continued denial

Step-by-Step Escalation

If your first appeal fails: Request Independent External Review. For medical necessity denials, external reviewers must be licensed physicians with relevant specialty training — they cannot be general administrators. This is one of the strongest categories for external review success.
