Coverage Summary
Overview: This policy (Policy Number CS356.D, status CURRENT) defines UnitedHealthcare's approach to observation level of care for hospital services.

The policy provides guidance for observation-level care, lists common conditions often managed on observation, excludes obstetric situations, and requires that if observation extends beyond 48 hours additional clinical information be submitted to support inpatient level of care.
