The short version for New Mexico
New Mexico's Office of Superintendent of Insurance runs a free external review: an independent reviewer outside your insurer re-decides medical judgment denials, and the insurer, not you, pays the reviewer. You have four months after the insurer's final internal decision to ask, and urgent cases can go straight to expedited external review. New Mexico also limits prior authorization and step therapy for drugs treating cancer, autoimmune disorders, rare diseases and substance use disorders, with serious mental illness added for policies starting in 2027.

Independent (external) review
- Process
- A state process. Run by New Mexico Office of Superintendent of Insurance, Managed Health Care Bureau, which appoints an independent review organization for each case.
- Where you file
- regulator
- How
- Send a written request, copies of your insurer's decision notices and a signed medical records release to the Office of Superintendent of Insurance, Attn: Managed Health Care Bureau - External Review Request, P.O. Box 1689, Santa Fe, NM 87504-1689, by email to mhcb.grievance@osi.nm.gov (subject: External Review Request), by fax to (505) 827-4253, or with the online complaint form. For an urgent case, call the Managed Health Care Bureau at (505) 827-4601 or 1-855-427-5674, and provide the complaint form, a signed release and a statement from your treating doctor. If you send the request to your insurer by mistake it must forward it to the Office within three days.
- Which denials qualify
- Denials after internal review that involve medical judgment: medical necessity, appropriateness, health care setting, level of care, effectiveness, or treatment the insurer calls experimental or investigational. The Office of Superintendent of Insurance itself (not an independent reviewer) can also review rescissions of coverage and denials that do not involve medical judgment.
- Appeal to the plan first?
- Yes, you generally complete the insurer's internal review first (you can choose an internal panel review within 15 days or go to external review within four months). If your situation is urgent you may ask for expedited external review right away. Members of public plans under the Health Care Purchasing Act must complete an internal panel review first.
Free help in New Mexico
- Office of Superintendent of Insurance, Managed Health Care Bureau
State staff take complaints about insurer grievances and denials, run the external review, and answer questions about the grievance process; the Centers for Medicare & Medicaid Services lists this office as New Mexico's consumer assistance resource, and it cannot give legal advice or act as your representative.
Phone: 855-427-5674
- New Mexico Legal Aid
Free civil legal advice, brief services and sometimes full representation for people who qualify; its consumer law program may help, but the page does not mention health insurance denials, so call to ask.

Medicare and Medicaid in New Mexico
- Medicare counseling
- New Mexico Aging and Disability Resource Center, State Health Insurance Assistance Program · 1-800-432-2080 . Free help with Medicare appeals.
- Medicaid agency
- New Mexico Health Care Authority (Turquoise Care Medicaid program)
- Fair hearing deadline
- Most appeals: no later than 90 days from the date of the action. After a Turquoise Care health plan upholds its denial: 90 days from the date of the plan's final appeal decision letter (30 days for an expedited hearing), according to a plan's member page. Your notice states the deadline that applies to you.
- Good to know
- If your Medicaid is run by a managed care plan, you must first appeal to the plan, within 60 days of its denial notice, and only then can you ask the Office of Fair Hearings for a state hearing. To keep a benefit you already have during the appeal, a nonprofit guide says to ask the plan within 10 days of its notice; the state page only says you may be able to continue benefits and may have to repay them if you lose. Office of Fair Hearings: HCA-FairHearings@hca.nm.gov, fax (505) 476-6215, mail Health Care Authority, Attn: Office of Fair Hearings, PO Box 2348, Santa Fe, NM 87504.
State laws that can help
-
Step therapy. Insurers must expeditiously grant an exception to a step therapy protocol, must cover the drug for at least as long as its therapeutic effect once an exception is granted, and a denied exception can be appealed under the Patient Protection Act.
-
Prior authorization. Insurers cannot require prior authorization or step therapy for FDA-approved drugs for cancer, autoimmune disorders, rare diseases and substance use disorders when a specialist-level provider finds them medically necessary (unless a generic or biosimilar exists); a 2026 amendment adds serious mental illness for policies issued on or after January 1, 2027.
-
Surprise billing. New Mexico's own law limits what you owe for out-of-network emergency care and out-of-network providers at in-network facilities to your in-network cost-sharing; if the insurer or provider does not fix a bill you can complain to the Office of Superintendent of Insurance.
-
Denial notice. When an insurer upholds a denial it must explain in plain terms why the service is not medically necessary or not covered, cite the clinical standards or plan provisions it relied on, name the reviewer, and tell you how to ask for an internal panel review or external review.
-
External review. The insurer pays for an independent reviewer appointed by the state, and the decision is binding on the insurer; you cannot request a second independent review of the same denial but may ask the Superintendent for a hearing within 20 days of the decision.

Not confirmed (16)
- The official independent review page. the Office of Superintendent of Insurance's own external review page was not found; the grievance procedures page it publishes covers only the internal process and links to a separate Independent Review Organization page that was not loaded. The external review details come from the regulations (13.10.17 NMAC on the Cornell Legal Information Institute site), whose text is not the state's own publication.
- The independent review request form. no standalone request form was found; the regulations say to use a form from the insurer, the Office, or the online complaint form.
- How long a standard independent review takes. the regulation says 20 days after the reviewer is appointed; one third-party site says 45 days. The regulation is used. The clock starts at appointment, not at your request.
- Which denials qualify for independent review. the exact scope of denials sent to the Superintendent for a hearing instead of independent review comes from a notice in the regulations and secondary sources; the 20-day hearing request and the four-month deadline for hearings were not checked on an official page.
- The deadline to request independent review. the 180-day deadline to ask your insurer for internal review (13.10.17.14 NMAC) is from secondary sources only and is omitted.
- The state regulators. the Office's own page does not say what it cannot regulate (self-funded plans) and gives no insurance-card tip; the self-funded statement comes from the Office's 2022 surprise billing press release, which says the federal government enforces rules for federally regulated and self-funded plans.
- The state regulators. taken from the Office's consumer assistance page; the form itself (hosted by the National Association of Insurance Commissioners) was not opened.
- The state regulators. 855-427-5674 is printed on the Office's pages; (505) 827-4601 is the Managed Health Care Bureau line given in the regulations and grievance page.
- How to tell whether the state regulates your plan. the Office's pages give no insurance-card tip, so null.
- The Medicaid fair hearing deadline. the 90-day figure for most appeals is from the Health Care Authority FAQ; the 90-day managed care figure and 30-day expedited figure come from one plan's (Blue Cross and Blue Shield of New Mexico) member page and a Disability Rights New Mexico guide, because the state FAQ does not list a managed care deadline. An older state rule (8.308.15 NMAC, seen in a search snippet) says 30 days after the plan's final appeal decision; this conflict was not resolved, so check the deadline on your decision letter.
- Notes on Medicaid appeals. the 10-day deadline to keep benefits during a plan appeal and hearing comes from the Disability Rights New Mexico guide and was not confirmed on a state page. The Office of Fair Hearings phone number could not be read reliably, so only email, fax and mail are given.
- Free consumer help programs. New Mexico Legal Aid's page lists consumer law but does not mention health insurance or Medicaid, and states no eligibility limits.
- Not confirmed. stateLaws (step-therapy) — the section 59A-22-53.1 text was read only in a search extract of the Justia copy; the 72-hour and 24-hour exception deadlines noted by third parties were not confirmed.
- Not confirmed. stateLaws (prior-authorization) — the section 59A-22B-8 text, including the 2026 amendment (effective May 20, 2026, applying to policies issued on or after January 1, 2027), was read on a non-official copy; the official bulletin confirms only the 2025 changes. The statute applies to individual and group plans listed in the act, not Medicaid or short-term plans.
- Not confirmed. stateLaws (surprise-billing) — a search listing of the Surprise Billing Protection Act shows at least one section (59A-57A-13) marked repealed effective July 1, but the year and effect were not checked, and the press release is from 2022.
- Not confirmed. stateLaws (mental-health-parity, ai-in-utilization-review, gold-card) — no New Mexico law on these topics was researched or confirmed.
