Postoperative Diagnosis: Carpal tunnel syndrome right wrist The patient was brought to the operating room and sedated by anesthesia. After sterile prepping and draping of the right hand, wrist and arm the patient’s area of incision was infiltrated with Xylocaine/Marcaine infiltration. After satisfactory anesthesia an Esmarch bandage was used to exsanguinate the right hand and wrist and used about the distal forearm as a tourniquet. A curvilinear incision was made on the palmar aspect of the right wrist. Dissection was carried out through the skin and subcutaneous tissue. Bleeding was controlled. The median nerve and it branches were identified, retracted, and protected at all times. The ligament was incised from proximal to distal. A thorough decompression was carried out. A neurolysis was carried out. The nerve was found to be flattened and ischemic underneath the transverse carpal ligament. The fascia was closed, the tourniquet was released. A dressing was applied and patient was transferred to recovery room. Code this procedure.
