Does Aetna Cover ABA Therapy in New Mexico
Applied behavior analysis (ABA therapy) is often the first and most vital recommendation for children diagnosed with autism spectrum disorder (ASD).
As the gold standard of treatment for the autism community, ABA therapy is an evidence-based approach focused on behavior and learning. It helps children build the social, communication and daily living skills necessary for greater independence and a higher quality of life.
However, ABA therapy can be an intensive commitment, both in terms of time and finances. Depending on a child’s specific needs, they may be prescribed up to 40 hours of therapy per week.
For families in New Mexico, managing the logistical and financial aspects of such comprehensive care is a primary concern.
The good news is that New Mexico has robust protections for families seeking autism services. In this article, we will explore whether Aetna covers ABA therapy in New Mexico and what steps you need to take to secure coverage for your child.

Does New Mexico Mandate Coverage for ABA Therapy?
New Mexico was an early leader in autism insurance reform. In 2009, the state passed Senate Bill 39, also known as “Andrew’s Law.” This mandate requires most state-regulated insurance plans to provide coverage for the diagnosis and treatment of ASD in children and young adults.

Under state law, coverage for ABA therapy is mandatory for many health insurance policies. The law generally applies to:
- Fully insured large group plans
- Fully insured small group plans
- Individual health insurance policies regulated by the state
While some self-insured or self-funded employer plans, often managed by large national corporations, are governed by federal ERISA laws rather than state mandates, many of these companies still choose to include ABA therapy benefits in their packages.
New Mexico’s mandate is particularly supportive of families because it provides significant coverage limits.
Currently, for state-regulated plans, the law mandates coverage for autism-related services up to age 19, or up to age 22 if the individual is still enrolled in high school. Furthermore, New Mexico has established generous annual caps for ABA therapy, ensuring that families have access to the intensive hours often required for successful intervention.

Does Aetna Cover ABA Therapy in New Mexico?
Yes, many Aetna insurance plans provide coverage for ABA therapy in New Mexico. Because Aetna is a major national provider, their plans are typically designed to comply with New Mexico’s state mandates.
It is important to remember that Aetna offers a wide variety of plan types, including HMOs, PPOs and POS plans. Each specific policy may have different rules regarding deductibles, co-pays and out-of-pocket maximums.
While the state mandate sets a floor for what must be covered, some Aetna plans may offer benefits that go beyond the state-mandated minimums.
Before starting treatment, it is essential to verify your specific policy’s benefits. This helps you understand not just if you are covered, but how that coverage is structured, such as whether you have a limit on the number of hours or if there are specific requirements for in-network versus out-of-network providers.

How Do You Get ABA Therapy Covered in New Mexico?
Navigating the insurance landscape can feel overwhelming, but the process for getting Aetna to cover ABA therapy generally follows a standard set of steps. To ensure a smooth approval process, keep the following requirements in mind.
Obtain an Official ASD Diagnosis
Aetna requires a formal diagnosis of ASD from a qualified healthcare professional. In New Mexico, this typically includes developmental pediatricians, child neurologists or clinical psychologists. Typically, the diagnosis must be based on comprehensive testing and not just a simple screening.
Secure a Letter of Medical Necessity
In addition to the diagnosis, Aetna will require a Letter of Medical Necessity (LMN). This is a document from your child’s physician or diagnosing clinician stating that ABA therapy is a medically necessary treatment for your child’s specific condition.
Seek Pre-Certification
Most Aetna plans in New Mexico require pre-certification, also known as prior authorization, before therapy sessions can begin.
This process involves your ABA provider submitting a detailed treatment plan to Aetna. The plan outlines the child’s current challenges, the specific goals the therapy will target and the number of hours requested per week.
Choose an In-Network Provider
While some plans offer out-of-network benefits, you will generally receive the highest level of coverage and the lowest out-of-pocket costs by choosing an ABA provider that is in-network with your Aetna plan.
Ongoing Authorization and Progress Reports
Insurance coverage for ABA is rarely a one-and-done approval.
Aetna will typically review your child’s progress every six months. During these reviews, your ABA clinic will provide progress reports showing how your child is meeting their goals.
An updated LMN from your doctor may also be required periodically to ensure that the intensity of the treatment remains appropriate for your child’s needs.
