New Mexico program
An outside review of an insurance denial
New Mexico’s insurance regulator can send an eligible denial to an independent reviewer.
What it is
New Mexico’s insurance regulator can send an eligible denial to an independent reviewer.
A final refusal from the insurer is not always the last word. On a plan New Mexico regulates, a reviewer outside the plan decides. A plan where the employer pays its own claims uses a federal route instead; one question to HR settles which.
Eligibility rules
- The state rule covers specified health plans, including public-purchasing arrangements. Private ERISA self-funded plans are excluded. The policy jurisdiction and employer’s legal type need checking.
- Requests generally must be made within four months of the final internal decision. Good cause can extend the filing period.
What you get
- No charge for an independent review.
- A binding reviewer decision for a case covered by the rule.
What this includes
- The independent reviewer appointed by the regulator issues a decision binding on the plan.
- You or the treating doctor can request urgent review by telephone.
If you decide to apply
- Ask the oncology team or social worker whether the denial fits the state review route.
- Have the final internal denial, complaint form and signed medical release ready. An urgent request also needs the treating doctor’s statement.
- For a standard request, use mhcb.grievance@osi.nm.gov with the subject “external review request”. Urgent requests can go by phone.

After you apply
- A standard decision is due within 20 days after the reviewer is appointed. An urgent decision is due within 72 hours of appointment.
- The Office of Superintendent of Insurance’s Managed Health Care Bureau takes requests at 505-827-4601 or 855-427-5674.
- The denial notice identifies whether medical review or an administrative grievance applies. The routes have different clocks and starting dates.
Good to know
If the employer pays its own claims, the federal route applies instead. A public-employer plan can follow its own rules; ask its administrator.
Other details
- A private ERISA self-funded plan generally uses federal appeal rights. HR can identify the governing plan document and review process.
- Rules amended November 19, 2024 exclude private ERISA self-funded plans from this state review route. A fully insured policy can fall under another state. Public purchasing arrangements can include self-insurance, so funding status alone does not decide jurisdiction.
Official sources
“If our plan denies needed care, could an outside review help? What are the benefits and drawbacks, and could you help us request the right review if it fits?”
Why I’m asking: We want to understand the next review route and its deadlines.

Who does what
The three parts, side by side. The agency decides; nobody on this page does.
You
Keep the final denial letter, file within four months, and say if it is urgent.
Your social worker
The oncology team writes the statement that makes an urgent review possible.
The care team
The treating doctor’s statement is required for an urgent review.
- Who decides
- An independent review organisation appointed by the insurance regulator.
- Ask the care team
- “The plan has denied this and the internal appeal is finished. Can you write the statement for an urgent outside review?”
How to apply
First step: Keep the final denial letter. You have four months from its date.
- Ask the plan for the final internal decision in writing and note the date.
- For an urgent case, call 505-827-4601 and ask the doctor for a statement the same day.
- Send the form and the signed release together; the clock starts when the reviewer is appointed.
Official application / program page ↗
Where it starts: Email a standard request to mhcb.grievance@osi.nm.gov with the subject “external review request”, or call 505-827-4601 or 855-427-5674 for an urgent one. Send the complaint form, a signed medical release and, for an urgent case, a statement from the treating doctor.
What to gather
The diagnosis letter, the child’s insurance card, and the last two pay stubs cover most applications. The official page lists the rest.
How long: Twenty days, or seventy-two hours for an urgent case, after the reviewer is appointed.
What a yes looks like
A written decision from the independent reviewer, binding on the plan.
What a no looks like, and the next move
A written scope refusal identifies the governing plan and any alternative state or federal review route.
Watch out
- The clocks run from the reviewer being appointed, not from the day you post it.
- Self-funded employer plans are outside this rule; ask HR which kind yours is.

The eligibility facts, as published
- Plan type
- insurers offering or administering health plans, including plans bought through the state purchasing route; self-funded plans under federal employee benefit law are excluded
- Timing
- within four months of the final internal decision
The trap: The twenty-day and seventy-two-hour clocks run from the reviewer being appointed, not from the day you post the request. Chase the appointment, not just the decision.
