MS HB199

Requires all health insurance payers authorized by the Mississippi Insurance Department to use Medicare Part A's "Two-Midnight Rule" criteria when determining whether 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/observation status

Aims to create consistency across all payers by standardizing inpatient admission criteria to match federal Medicare standards
