MS HB97

Requires all health insurers authorized by the Mississippi Insurance Department to use Medicare Part A's "Two-Midnight Rule" when determining whether hospital inpatient admissions are reasonable and necessary

The Two-Midnight Rule establishes that inpatient admission is generally appropriate when a physician expects a patient to require hospital care spanning at least two midnights

Aims to standardize criteria across all payers to improve consistency and efficiency for health care providers, insurers, and patients
