How to Appeal a Mental Health Insurance Denial in New York
Short answer
Most New York-regulated plans give you two steps. First, an internal appeal to the plan, which DFS says you have 180 days to file. If the plan upholds the denial, you can ask the Department of Financial Services for an external appeal decided by independent reviewers, generally within four months of receiving the final denial. Self-funded employer plans follow federal rules instead, so check your denial letter for its exact deadlines.
In crisis or thinking about suicide? Call or text 988 now (in New York City it reaches NYC 988). If you are in immediate danger, call 911.
This guide is not enough if
- You need care right now. If you are in crisis, call or text 988, or call 911 if you are in immediate danger. Do not wait on an appeal.
- You have Medicare. Medicare has its own appeal levels and notices.
- The problem is a missing code or a typo on a claim. A corrected claim is usually faster than an appeal.
- You want legal advice. This page is general information only.
A denial letter is not the last word
A denial for therapy, a psychiatric evaluation or a medication visit can feel final, especially when you are already struggling. In many cases it is the start of a process with set steps and deadlines, and you are allowed to use them.

Find out which rules apply to your plan
DFS says New York's rules apply to individual and group policies that you or your employer buy in New York. For a self-funded employer plan, an insurer may still process the claims, but DFS says New York protections do not apply. Those plans follow federal rules from the U.S. Department of Labor.
Look for "fully insured coverage" on your ID card, which DFS says means your coverage follows New York law, or ask your benefits office. Medicare has a separate appeal system. Your denial letter should also name the type of plan and the steps it offers.
Step 1: the internal appeal
The internal appeal goes to your plan. DFS says you or someone you choose (a designee) can submit it within 180 days. New York law sets a floor of 45 days, so use the date in your own letter. Then:
- Read the reason. "Not medically necessary," "experimental," "out-of-network" and "missing information" each call for a different response.
- Ask for the criteria. DFS says you can request a copy of the clinical review criteria the plan used, and that New York insurers must use state-approved tools to decide whether mental health care is medically necessary.
- Ask your clinician for a letter. It works well when it answers the plan's criteria point by point and attaches the records that show each one.
- Know who decides. Under Insurance Law section 4904, a clinical peer reviewer who did not make the first decision hears the appeal.
- Know the timing. The law gives the plan 30 days after it receives the necessary information for a standard appeal, and 2 business days for an expedited appeal when your provider believes an immediate appeal is warranted.
What to put in your appeal packet
A strong appeal is usually an organized one. Reviewers decide on what reaches them, so gather the pieces before the deadline gets close:
- The denial letter, the claim or reference number, and the date you received the letter.
- The plan's clinical review criteria or policy, with its name and date.
- A letter from your psychiatrist, therapist or other clinician that addresses each criterion.
- Records that back up the letter, such as dates of earlier treatment, medicines tried and why they stopped, and any rating scales your clinician used.
- A short statement from you, if you want, about how symptoms affect work, school, family or safety.
- A log of every call: date, name, what was said and any reference number.
- A copy of everything you send, and proof of how and when you sent it.
Step 2: a New York external appeal
If the plan upholds its denial, it issues a final adverse determination. You can then ask DFS for an external appeal, which a medical expert independent of your plan decides. These points come from the DFS external appeal page, its application form and Insurance Law section 4914:
- What qualifies: denials for care the plan calls not medically necessary, experimental or investigational (including clinical trials and rare diseases), out-of-network services or referrals, formulary exceptions, and certain No Surprises Act denials.
- Your deadline: the law gives you four months after you receive the final adverse determination. A 2025 DFS flyer says 120 days, which can be a little shorter, so plan around the earlier date.
- Who can file: you, your designee, or your provider. A provider appealing on its own behalf has 60 days, and only for services already provided.
- A second internal level is optional. If you use it, DFS says the four months still run from the first appeal decision.
- Decision times: 30 days for a standard appeal and 72 hours for an expedited one. You can ask for an expedited internal and external appeal at the same time.
- Paperwork: a signed consent to release records, plus a physician attestation for expedited appeals and for most denial types other than "not medically necessary." A plan may charge a fee; it is waived for Medicaid, Child Health Plus or hardship and returned if you win.
| Reason on the letter | Usual first move | If the plan says no again |
|---|---|---|
| Not medically necessary | Internal appeal with the plan's criteria and a clinician letter that answers each one | External appeal through DFS |
| Experimental or investigational | Internal appeal; ask exactly which policy the plan applied | External appeal with a physician attestation |
| Out-of-network service or referral | Internal appeal with your physician's statement on why in-network options do not fit | External appeal (out-of-network or referral type) |
| Missing information, coding or late filing | Corrected claim or resubmission; ask the plan which route it wants | Internal appeal if it is still denied |
| Waiting could seriously harm your health | Ask for an expedited internal appeal | Expedited external appeal, which can be filed at the same time |
| Self-funded employer plan | Internal appeal under the plan's federal process | External review as your denial notice describes |
If your plan is self-funded
The Department of Labor says you have at least 180 days to appeal a denied claim under a job-based plan, and your summary plan description may allow longer. The plan must give you copies of documents and records relevant to your claim, free of charge, if you ask.
The external review route depends on whether the plan is self-funded or insured, and your denial notice should describe it. Labor Department benefits advisors can help for free through askebsa.dol.gov. If the denial looks harsher than how the plan treats medical care, federal parity rules may matter.
When an appeal is not the right next step
Some problems are faster to fix another way. A missing code or a wrong member ID usually needs a corrected claim. A dispute about how much an out-of-network claim paid may not fit the external appeal categories, so DFS complaints are another route. If no in-network clinician can see you in time, an access complaint may fit better; see when you can't find an in-network psychiatrist.
Do not let an appeal delay care you need. Talk with your clinician about a plan for the meantime, and compare in-network, out-of-network and self-pay if you need to keep going while you wait. Mind Body Seven is out-of-network with all plans, files out-of-network claims for many clients with Cigna, Aetna or BCBS plans, and offers superbills in its patient portal; details are on the fees and insurance page.
Frequently asked questions
Do I have to file a second internal appeal before going to DFS?
No. DFS says that if your plan offers a second level of internal appeal, you do not have to use it. If you choose to, you still must send your external appeal to DFS within four months of the first appeal decision. Waiting on a second level can use up most of your window, so mark the date as soon as the first decision arrives.
What if my plan misses its own appeal deadline?
The New York external appeal application lists a plan's failure to follow internal appeal requirements as one way to become eligible for external appeal. Keep proof of when you filed and what you sent. If you are unsure whether the plan missed a deadline, DFS answers external appeal questions, and New York's Behavioral Health Ombudsman program (CHAMP) can help with mental health appeals.
Can I appeal if my plan won't pay for an out-of-network therapist?
Sometimes. DFS lists out-of-network denials among those that can go to external appeal, for example when the plan says an in-network service would work instead. A disagreement about the size of an out-of-network payment is different and may not qualify. Read the reason in your letter, and ask the plan in writing which appeal rights apply to that decision.
Is there a fee for a New York external appeal?
There can be. The DFS application says a plan may require a fee, that it is waived for people covered by Medicaid or Child Health Plus, and that you can ask for a hardship waiver. If the appeal is decided in your favor, the fee is returned to you. Some plans charge no fee at all; your denial letter should say.
