What is an internal appeal?
An internal appeal asks the utilization review agent or health plan to reconsider an adverse determination—when the plan says care is not medically necessary, experimental, or investigational, or denies PA or a claim.
This is different from external review, where DFS assigns an independent appeal agent after internal review is complete (with limited urgent exceptions).
New York also has separate grievance procedures for many non-clinical disputes. Your denial letter should say whether you are appealing a utilization review determination or filing a grievance.
General walkthrough: Appeals roadmap.
New York appeal timelines
Filing deadline
- Utilization review appeals: the agent must allow at least 45 days after notice and necessary information to file an appeal (Insurance Law § 4904(c))
- DFS consumer materials often describe 180 days to appeal many denials on qualified health and commercial plans—use the deadline in your letter if it is longer
- Appeals may be filed in writing or by telephone (§ 4904)
Decision deadlines
- Standard appeal: written acknowledgment within 15 days of filing; decision within 30 days after receipt of necessary information (recent reforms shortened this from 60 days)
- Expedited appeal: within 2 business days of receipt; certain inpatient substance-use disorder appeals within 24 hours
- Appeals reviewed by a different clinical peer than the person who made the initial denial (§ 4904(d))
If the carrier is late
Failure to make a timely internal appeal determination is deemed a reversal of the adverse determination (§ 4904(e))—the denial is treated as overturned.
Grievances (DFS summary)
DFS describes typical grievance decision timeframes as:
- Urgent: 72 hours
- Pre-service: 15 days
- Post-service: 30 days
- Other: 60 days
How to file
- Read the denial for appeal vs. grievance instructions and deadlines.
- Submit before the deadline—phone appeals are allowed for UR appeals when the plan permits it.
- Include clinical support and request the criteria the plan used.
- Request expedited review if delay would cause serious harm.
- Keep copies of everything sent and the date sent.

Evidence that helps
- Treating clinician letter on medical necessity
- All records the plan relied on—or should have considered
- Peer-reviewed literature for experimental/investigational disputes
Medicaid appeals
Medicaid managed care requires a plan appeal before most fair hearings:
- Plan appeal: typically 60 calendar days from an Initial Adverse Determination (IAD) notice
- Plan must issue a Final Adverse Determination (FAD) before you request a state fair hearing in most cases
- Medicaid fair hearing: request within 120 calendar days of the FAD (NYSDOH managed care appeals)
- For aid continuing during a fair hearing after a reduction, request within 10 days of the FAD notice
- Some medical-necessity denials may also qualify for DFS external review—follow your FAD notice
After internal appeal
If you receive a final denial, request external review from DFS within four months (DFS — file external appeal).
