ABA insurance and Medicaid coverage in Missouri
Last researched October 21, 2026
Who pays for ABA in Missouri, and what a practice has to do to bill them. Coverage details here come from statutes and agency pages we read, not from payer marketing.
Autism insurance mandate
- State mandate for autism coverage
Yes, the research found a state autism coverage law.
- Statute
RSMo 376.1224
- Age limits
As of 2026-10-21, the statute text on revisor.mo.gov states ABA coverage applies through eighteen years of age; other required autism coverage is not subject to the age and dollar limitations.
- Annual cap
The statute text sets a $40,000 base ABA maximum per calendar year for individuals through age 18. The Missouri Register notice (v51n4, page 317) publishes an adjusted 2026 maximum of $58,817 (calculated as the 2025 limit of $57,311 x 321.943/313.698), based on CPI-U. Carriers must adjust at least triennially. Coverage above the maximum is available with prior plan approval if medically necessary. The official FAQ is stale on the cap, and the $55,000 figure in older bill texts is not current law.
- Excludes self-funded employer plans
It depends.
- Notes
The statute reaches specified governmental, school-district and other arrangements to the extent not preempted by federal law. Federally preempted private self-funded ERISA plans are generally excluded. The January 1, 2020 date in the statute is the applicability date for the current text, not the original enactment date. Section 376.1224 does not address telehealth.
