Relates to insurance coverage for pediatric acute-onset neuropsychiatric syndrome

S 2655 requires health insurance plans to cover rehabilitation treatment for children diagnosed with pediatric acute-onset neuropsychiatric syndrome (PANS). Insurance companies must provide this coverage when a child's doctor certifies in writing that the treatment is medically necessary. The bill applies to all health insurance policies, including group plans, directly affecting families with children who have PANS and the insurance providers. It references an existing definition of PANS from New York's public health law to ensure consistent application.
