    These codes include preop, the service, and post op, is it possible that another physician billed for part of the service? On the E&M's, could they be within the global of a procedure?

    Default COB20 denials

    We are now getting these denials on x-ray films. Pt was transferred from another hospital and films taken at that hospital didn't come with the patient. We are billing the professional component of a X-ray that was taken at our hospital and are getting denials. Should we just add the 77 modifier? That is what Medicare is telling us to. Just not comfortable with that when we dont' know what films were taken at the other hospital.
