We have a medicare patient that had surgery out of state for mass of the abdomen/hernia repair (codes 49566/49568/15734/51860) by a physician in Missouri. Patient returned home and we continued post op care, and eventually the patient had to be admitted to the hospital during the global period (within a month) for abdominal wall cellulitis/drainage, which is a complication of the origianl surgery. We have been reimbursed for the post op care, but cannot get reimbursed for the hospital care (pt was in hospital for several days). Are there any suggestions on what modifiers to use so that we can be reimbursed for our services, or do we have to consider this part of the global period and not be compensated? Any suggestions would be appreciated. Thanks in advance.
