External review in New York: the DFS external appeal

How New York's external appeal works

New York's external review is the external appeal, run by the Department of Financial Services (DFS). It covers denials a plan based on medical necessity, an experimental or investigational determination, or an out-of-network decision. What sets New York apart is who picks the reviewer: DFS assigns the case to a certified, independent external appeal agent — the health plan does not choose it.

• Eligible denials: not medically necessary, experimental/investigational, or out-of-network.
• DFS assigns the independent external appeal agent; the plan cannot pick the reviewer.
• The agent's decision binds the plan — if it overturns the denial, the plan must cover the service.

Deadlines — and a separate, shorter clock for providers

A patient (or their designee) generally has four months from the plan's final adverse determination to request an external appeal. A provider appealing on its own behalf has a much shorter window — 60 days. Miss the deadline and the appeal is time-barred, so the provider clock in particular is one to calendar the day the final denial arrives.

How to file

1. 1

   Finish the internal appeal

   Complete the plan's internal appeal (or obtain a waiver) first — the external appeal follows the final adverse determination.

2. 2

   Complete the DFS external appeal application

   File through the DFS Portal (preferred), or by email, fax, or mail to the Department of Financial Services in Albany. A paper application can be requested at 1-800-400-8882.

3. 3

   Attach the denial and the clinical record

   Include the plan's final denial and the documentation that supports medical necessity.

4. 4

   DFS assigns the reviewer

   You'll be notified when the case is assigned to an external appeal agent — you don't select one.

How fast — and the fee

• Standard external appeal: decided within 30 days.
• Expedited (urgent): within 72 hours — or 24 hours for a non-formulary prescription-drug denial.
• Fee: a plan may charge a patient up to $25 per appeal, capped at $75 per plan year — waived for Medicaid, Child Health Plus, and hardship. A provider pays up to $50, refunded if the denial is overturned.
• The decision is binding on the plan.

New York publishes its external-appeal decisions

New York is one of the few states where you can look up how independent reviewers actually decided: DFS keeps a public, searchable database of closed external appeals, and its annual report tabulates determinations by type. Before filing, it's worth checking how comparable denials — the same service, the same grounds — have gone, and building the request around the arguments that carried.

For New York providers and billers

Two New York specifics matter to a practice. First, the 60-day provider filing window is far tighter than the patient's four months — miss it and the strongest escalation is gone. Second, New York's step-therapy override law (in effect since 2017) requires a plan to decide an override request within 72 hours — 24 hours when urgent — and a plan that misses the timeframe is deemed to have granted the override. That's a lever worth invoking by name when a 'fail first' requirement is blocking the right drug.
