Medicare is removing more procedures from inpatient only status. Some people have been annoyed in the past that they had a procedure, stayed overnight in the hospital but were "outpatients" for billing purposes IIRC one issue was for a person who was working and had part A but employer health insurance for outpatient procedures but with a large deductible.
