Insurance: health insurers; coverage for treatment of menopause and perimenopause symptoms and waiver of prior authorization for prescription drugs or treatments for menopause and perimenopause symptoms; require. Amends 1956 PA 218 (MCL 500.100 - 500.8302) by adding sec. 3406zz.

Maddy summaryThis bill requires Michigan health insurers to cover medically necessary treatments for menopause and perimenopause symptoms, including FDA-approved hormone therapy. It specifically prohibits insurers from demanding prior authorization, step therapy, or "fail-first" protocols for hormone therapy prescriptions related to these conditions. The law applies directly to health insurance policies sold in Michigan and affects patients experiencing menopause or perimenopause symptoms who seek treatment. Key provisions ensure coverage for treatments without additional administrative barriers typically imposed by insurers. The bill defines menopause as permanent cessation of menstruation and perimenopause as the transitional phase before menopause.

Maddy summarySB 717 requires Michigan's Medicaid program to cover medically necessary treatments for menopause and perimenopause symptoms, including hormone replacement therapy and FDA-approved treatments, without requiring prior authorization. The bill prohibits step therapy or "fail-first" protocols for these treatments, meaning patients won't be forced to try other medications first. This applies to all Medicaid beneficiaries in Michigan seeking care for these conditions and directly affects how the state's health department administers coverage under the medical assistance program.

Civil rights: sexual orientation discrimination; certain references to marriage; make gender neutral. Amends sec. 1, art. X & repeals sec. 25, art. I of the state constitution

Maddy summaryThis constitutional amendment proposal (SJR F) removes gender-specific language from two Michigan Constitution sections. It repeals the current definition of marriage as "the union of one man and one woman" (Article I, Section 25) and updates property rights language to be gender-neutral (Article X, Section 1). The change would affect all Michiganders by eliminating gender-based restrictions in marriage recognition and ensuring property rights for married individuals are defined without gender distinctions. If approved by voters, it would amend the state constitution to reflect these neutral terms. The bill is currently in committee for review.

Maddy summarySB 255 would decriminalize restoring water service to a lawfully occupied home after a shutoff due to non-payment, provided no metering or backflow devices are damaged. It changes penalties from potential felony charges to civil violations, with first offenses requiring up to 25 hours of community service, and repeat offenses limited to fines under $500 or up to 100 hours of service. The bill applies specifically to residents who restore service themselves, not utility workers or others. It also mandates referrals to water assistance programs for those cited under this provision.
