MO SB887

Adds Lyme disease to Missouri's list of reportable communicable diseases, requiring health care providers, laboratories, and local health departments to report confirmed or suspected cases within seven days of diagnosis

Creates the "Lyme Research and Eradication Fund" in the state treasury to distribute grants to universities, research institutions, and nonprofits for developing improved diagnostics, treatments, and tick population control strategies, with at least 20% of funds directed to rural counties

Requires health benefit plans issued on or after January 1, 2027 to cover Lyme disease diagnostic testing, antibiotic therapy (minimum 28 days for acute cases, 90+ days for posttreatment syndrome), supportive therapies, and holistic/herbal treatments without prior authorization for testing or antibiotic therapy

Prohibits insurers from denying coverage based solely on Infectious Disease Society of America guidelines deeming extended antibiotic therapy experimental, and bars step therapy or fail-first requirements that differ from those for similar conditions

Protects health care providers from license discipline solely for prescribing extended antibiotic therapy or other treatments deemed medically necessary for Lyme disease or posttreatment Lyme disease syndrome
