MS HB66

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

The Two-Midnight Rule generally requires that a patient's hospital stay be expected to span at least two midnights for the admission to qualify as inpatient rather than outpatient

Aims to standardize hospital admission criteria across all insurers to improve consistency for healthcare providers, payers, and patients
