The EH shall establish inpatient stabilization and observational admission criteria appropriate to treat patients that require short periods of extended care that cannot be provided in an emergency room setting. The criteria may be based on diagnosis and patient acuity established by the medical and professional staff or the EH may use diagnosis related groups (DRGs). Such admission criteria shall not in any way be based on payer source. The criteria shall be established and revised as necessary by the medical and professional staff and approved by the governing body. Stabilizing emergency treatment services provided shall not be restricted by inpatient admission criteria.
