Requires Medicaid and health insurance network contracts to provide participating health care providers with certain notifications.

S 3733 requires New Jersey's Medicaid program, FamilyCare, and health insurance carriers to give participating health care providers at least six months' advance notice before changing policies that could deny coverage for services the provider offers to patients. This applies to all managed care plan contracts, ensuring providers have sufficient time to adjust to coverage changes affecting their ability to bill for services. The law takes effect 120 days after enactment for new or renewed contracts.
