What external review covers
External review applies to adverse benefit determinations involving medical judgment — denials based on medical necessity, appropriateness, level of care, effectiveness of a covered benefit, or whether a treatment is experimental or investigational. It also covers rescissions of coverage. It does not apply when the denial is based on an explicit benefit exclusion in your plan document.
For an expedited request (when the standard timeframe would seriously jeopardize life, health, or ability to regain maximum function), the reviewer must decide as soon as possible and no later than 72 hours.
How to file in New York
- Exhaust the insurer's internal appeals process. Keep the final adverse benefit determination letter — you'll need it.
- Open the New York external review page at https://www.dfs.ny.gov/complaints/file_external_appeal and use the request form posted there.
- Submit the final denial letter, your provider's medical necessity letter, supporting medical records, and any relevant guideline or peer-reviewed citations. The state-assigned IRO will review the full record.
- The standard decision is typically issued within 45 days. The insurer is bound by the decision if the IRO reverses the denial.
New York notes
New York's external appeal program under Insurance Law Article 49 is one of the most-used in the country. File with DFS within four months of the final adverse determination; a $25 filing fee may apply (refunded if you win).
