Patient had a rectosigmoid resection and rectopexy. This is a patient with multiple conditions. Normal hospital stay is 5-7 days - she was in for 11 days. She has MS, asthma, protein C deficiency and diabetes. My surgeon wants to know if he can charge for any subsequent visits. I am aware that for medicare you can only use 24 modifier for "underlying" conditions. I do have documentation of surgeon adjusting Lovenox then Coumadin levels on patient due to her protein C deficiency - she was followed by a hospitalist for her diabetes...To me this is an "underlying condition" - feed back to charging would be appreciated...
