ABA insurance and Medicaid coverage in Mississippi
Last researched October 21, 2026
Who pays for ABA in Mississippi, 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
Miss. Code Ann. 83-9-26
- Age limits
As of 2026-10-21, per the Mississippi Insurance Department page: ABA coverage is capped at age 8, but Section 83-9-26(5) permits medically necessary extensions of both the age and hourly limits. The Insurance Department page also indicates some insurers have voluntarily removed age limits; verify with the particular plan.
- Annual cap
No fixed annual dollar amount is specified in the sources reviewed, but subsection (2) imposes parity protections, so this should not be read as unlimited benefits. Weekly limits: ABA up to 25 hours/week in total, with licensed behavior analyst services up to 10 hours/week within that 25-hour total, per the Insurance Department page. Section 83-9-26(5) permits medically necessary extensions of the hourly limits.
- Excludes self-funded employer plans
It depends.
- Notes
Coverage applies to policies issued or renewed on or after January 1, 2016. Applies to all large group plans and to all grandfathered (pre-March 23, 2010) individual and small group plans. Plans federally preempted from state mandates, including applicable self-funded ERISA plans, are not subject to the mandate. Under subsection (9), small employers must be offered the coverage, and its cost may be charged to participants. The official statute PDF was reviewed by the fact-checker and the core coverage claims match the Insurance Department summary. Verify the particular plan's funding type and grandfathered status before relying on this.
