X-POST Useful Medicare PA insurance nugget

If the surgery is done on an outpatient basis - insurance *cannot* be submitted for prior autthorization retroactively. GUARANTEES non-coverage.
If the surgery is done INPATIENT - including hospital stay for at least 24 hours post op - retroactive PA can be done *up to 90 days post-procedure* They could conceivably still deny, but I'm thinking if inpatient is necessary, they would be nuts not to! If they did, you could still appeal!
