I am currently trying to bill for an operative report done by our physician at our local hospital with POS 21, the patient was approved for a 7 day admission which has now continued into week 3 with no set day of release. How do I bill for my physicians scheduled operative report done in the hospitals operating room while the patient is still admitted and I do not have a discharge date to put on my HCFA? our clearinghouse kicks it back to me if I do not have the hospitalization dates and I can not use POS 22 as this was not outpatient surgery. Please help
