Verify applicable procedure and global policy coding via the Medicare Physician Fee Schedule Database (MPFSDB) to determine where the global surgical policy applies.
Medical record must include the ordering provider's assessment related to the patient's complaint, relevant medical history, and results of pertinent tests/procedures.
