Step-by-step in New York
- Read the denial notice. The reason code drives your evidence and the appeal deadline is on the letter.
- File the internal appeal with your insurer within the plan's window (typically 180 days for ERISA/ACA plans; expedited turnaround 72 hours for urgent cases).
- Attach medical necessity evidence that maps to the exact denial reason: guideline citations, chart notes, prior-therapy documentation, peer-reviewed literature.
- Optional: file a complaint with New York Department of Financial Services (DFS) at www.dfs.ny.gov/. A DOI complaint runs in parallel — it does not replace the internal appeal.
- Request external review within 4 months of the final internal denial. In New York, external review is administered by New York Department of Financial Services (DFS). The IRO decision is binding on the insurer.
