Getting Autism Therapy Covered by Insurance in New Mexico

New Mexico’s mandate

NMSA § 59A-22-49 and parallel sections, as amended by HB 322 (2019) requires state-regulated health plans in New Mexico to cover the diagnosis and treatment of autism spectrum disorder, including applied behavior analysis.

Ages covered: No age limit. HB 322 struck the previous ceiling — 19, or 22 if still in high school — with effect from June 2019, extending coverage to transition-age young people and adults.

Dollar cap: None. The same amendment removed the old $36,000 annual limit and the $200,000 lifetime limit, replacing them with language that coverage shall not be subject to annual or lifetime dollar limits.

Covered treatment is defined to include speech therapy, occupational therapy, physical therapy and applied behavior analysis, and the change reaches group plans, individual policies, HMOs and nonprofit health care plans alike. For an autistic adult in New Mexico this is one of the better positions in the country.

Whether the mandate applies to your plan

This is the question to settle first, because the answer decides whether anything above is enforceable for you. State insurance mandates bind fully insured plans. Self-funded employer plans — where the employer pays claims itself and an insurer only administers them — are generally exempt under federal ERISA, and they cover roughly six in ten people with employer coverage.

Ask your HR department, in writing, which type your plan is. If it is self-funded, NMSA § 59A-22-49 and parallel sections, as amended by HB 322 (2019) does not compel coverage — but federal parity law may still help, and many large self-funded employers cover ABA voluntarily. Ask what the plan actually covers rather than assuming the answer is no.

The Medicaid route

HB 322 went further than most states here: it applied the same rule to the state medical assistance program, requiring coverage that is not subject to age restrictions or dollar limits. New Mexico Medicaid is therefore covered by the same guarantee, not merely by federal EPSDT.

How Medicaid waivers work covers the route for families who do not qualify on income alone.

When you are denied

1. Get the denial reason in writing. Insurers must give a specific reason, and the appeal has to answer that reason rather than restate the diagnosis.
2. File the internal appeal within the deadline on the denial letter, with a letter of medical necessity that addresses the stated reason directly.
3. Request external review if the internal appeal fails. Fully insured plans carry external review rights, and an independent reviewer overturns denials more often than families expect.
4. Complain to the New Mexico Office of Superintendent of Insurance on 1-855-427-5674 if you believe NMSA § 59A-22-49 and parallel sections, as amended by HB 322 (2019) is being violated. Their consumer pages are here.
