I am new to UBO4 billing and am billing for an ambulatory surgical center. Just wondering if we are only allowed to bill 490 for the actual procedures rendered or if we can also be billing seperately for items like implant, plates & screws, or items such as prophylactic medications administered, recovery room time, or surgical supplies used. I guess an example would be...a fracture which was fixed, but the patient was given IBUProfen and prophylactic antibiotics before surgery. The surgery was performed using plates and screws, and then the pt was taken to recovery and discharged from there. Can you give me any insite as to what items can all be billed and what types of rev codes would be used other then the 490? Any info is helpful.
