Bill Overview

Analyzed Economic Effects

3 provisions identified: 0 benefits, 0 costs, 3 mixed.

Health plans must cover detransition

The law requires any plan that covers gender transition care to also cover detransition care with the same deductibles and copays. This applies to private insurance, state employee and university plans, Medicaid, and the state’s temporary benefits program. For Medicaid and the temporary program, these rules begin Oct 1, 2026. If a plan or program later ends transition coverage, it must keep detransition coverage only for people who were enrolled and got transition benefits. The law defines transition care to include listed surgeries, supraphysiologic hormones, and puberty blockers.

New deadlines to sue over care

The law creates a right to sue for injuries from gender transition treatment received as a minor, but sets strict filing windows. You must file by age 25 or within 2 years after you discover the injury and its cause, whichever is later. No case may be filed after age 30. For medical malpractice against listed providers, you must file within 2 years of the injury or discovery, with a hard 5‑year limit; if the child was under age 4, the clock starts at age 8. Tolling applies if a provider failed to disclose an error that reasonable care would have found. These malpractice timing rules apply beginning Oct 1, 2026. If Senate Bill 218 is also law, claims under it must use these same time limits.

New rules for HMOs and MEWAs

Beginning Oct 1, 2026, HMOs and self‑funded employer MEWAs must also follow section 2 of this act. They are subject to the same listed insurance‑code requirements for those plan types. This changes plan compliance and administration and may affect how plans operate.
