NMExternal review · New Mexico

New Mexico names the treating provider as a party

In most states a practice appeals on the patient's behalf and hopes the rules accommodate it. New Mexico writes the provider into the definition: a grievant includes a provider or other health care professional with knowledge of the covered person's medical condition, acting on the patient's behalf and with their consent.

New Mexico's external review runs under 13.10.17 NMAC, the Grievance Procedures rule, administered by the Office of Superintendent of Insurance. A grievant must file a written request for independent review within four months from receipt of the written notice of the final internal review decision, unless the Superintendent extends that for good cause shown. The Superintendent randomly assigns an independent review organization from an approved list. A standard decision is due within 20 days after appointment, and an expedited one as soon as possible and no later than 72 hours. The health care insurer against which the request was filed pays the reviewer's fees, remitting within 30 days of the invoice. Internal review is deemed exhausted where the insurer waives it, fails to comply with its own process, or where expedited internal and external review are requested at once.

The provider is a grievant, not a proxy

The rule's definition at 13.10.17.7(R) includes, within the meaning of grievant, a provider or other health care professional with knowledge of the covered person's medical condition, acting on behalf of and with the covered person's consent. The consent requirement is real and has to be documented, but once it exists, the treating clinician is a party to the process rather than a witness to it.

Plan type still governs

State external review applies to fully insured plans. ERISA self-funded plans are not subject to state insurance law — their external review runs through the federal process regardless of the state. Confirm the plan type before choosing a path.

Twenty days is the whole review

This is the fastest standard external-review clock in the country. Under 13.10.17.22(A)(2) the independent review organization must decide within 20 days after appointment by the Superintendent — less than half the 45 days that most states allow. Expedited review under 13.10.17.22(A)(1) is due as soon as possible and in no case later than 72 hours after appointment.

  • Filing window: 4 months from receipt of the final internal review decision.
  • Extension: available where the Superintendent finds good cause shown.
  • Standard decision: 20 days after appointment of the reviewer.
  • Expedited decision: no later than 72 hours after appointment.

A short clock rewards a complete file

Twenty days leaves no room for a reviewer to chase records. Everything the argument rests on — the criteria, the notes, the imaging, the failed alternatives — has to be in the submission when it goes.

The Superintendent picks the reviewer, at random

Under 13.10.17.22(D)(1) the Superintendent randomly assigns an independent review organization from the Superintendent's list of approved organizations. Neither the insurer nor the grievant chooses, and the rule contemplates that in some circumstances the external review is conducted by the Superintendent rather than by an appointed organization at all.

The insurer pays for the review

Cost is allocated by rule rather than left to the parties. Under 13.10.17.19(E) the health care insurer against which a request for external review has been filed is responsible for paying the fees of the independent review organization, and it must remit payment within 30 days after receiving the invoice. For a practice weighing whether escalation is worth it, the review itself carries no charge to the patient.

Three ways the internal appeal is deemed finished

The Superintendent may require internal grievance procedures to be exhausted before accepting a grievance for review. But the rule then sets out when exhaustion is unnecessary and the internal process is deemed exhausted:

  • The health care insurer waives the exhaustion requirement.
  • The insurer is considered to have exhausted the internal process by failing to comply with the requirements of that process.
  • The grievant simultaneously requests an expedited internal review and an expedited independent review.

A carrier that breaks its own rules ends its own gate

The second ground is the useful one. Where an insurer has not followed the requirements of its own internal review — missed its deadlines, skipped a step — the exhaustion requirement is treated as satisfied rather than as a reason to keep waiting.

What counts as final

The rule defines a final adverse determination as an adverse determination that has been upheld by a health care insurer at the conclusion of the internal review process. That is the document whose receipt starts the four months — not the first denial, and not an interim communication about the appeal.

For New Mexico practices

Get the patient's written consent early and keep it with the file, because it is what makes the practice a grievant in its own right rather than a correspondent. Then build for speed: with 20 days from appointment to decision and a randomly assigned reviewer who will not know the case, the submission has to be self-contained. And where the carrier has mishandled its own internal review, say so explicitly — under this rule that is a route past the exhaustion requirement, not merely a complaint.

Frequently asked

Four months from receipt of the written notice of the final internal review decision, unless the Superintendent extends it for good cause shown.

Yes. The rule defines a grievant to include a provider or other health care professional with knowledge of the patient's medical condition, acting on their behalf and with their consent.
How fast is the decision?
20 days after the reviewer is appointed on the standard track, and no later than 72 hours on the expedited track.
Who chooses the reviewer?

Who pays for the review?
The health care insurer the request was filed against, which must remit payment within 30 days of receiving the invoice.
