MO HB2051

Adds section 191.635 to Missouri law establishing physician authority to diagnose and treat "Master's disease," defined as acute or chronic tick-borne illness with Borrelia bacterium causing pain, fatigue, cognitive, ophthalmic, and neurological disorders.

Permits physicians to diagnose Master's disease based on clinical assessment, physical examination, and optional diagnostic tests without requiring CDC surveillance criteria or erythema migrans rash confirmation.

Authorizes physicians to prescribe long-term antibiotic therapy (oral, intramuscular, or intravenous for periods exceeding four weeks) for clinically diagnosed Master's disease patients with documented diagnosis and treatment plans.

Prohibits the Missouri State Board of Registration for the Healing Arts from initiating disciplinary action against physicians solely for prescribing long-term antibiotic therapy for Master's disease when properly documented.

Eliminates the requirement for physicians to obtain second opinions from other physicians or medical specialists before continuing long-term antibiotic therapy for Master's disease treatment.
