What are the ICD-10-PCS codes for the skin biopsies?
ICD-10-PCS Codes: 0HBMXZX Diagnostic excision of skin of the right foot by external approach.
From a procedural standpoint, there are a number of factors that need to be considered. First the Root Operation, which indicates what was done. The two options for this case would be Excision (removing part of a part) or Resection (removing all of a part). As these are procedures performed on the skin, and all the patient’s skin was not removed, even though all of the lesions were removed, these procedures are Excisions. As they were performed on two separate body part sites, two codes are reported.
The biopsy for the ankle is coded to the foot. According to the guidelines (B4.6), if a procedure is performed on the skin, subcutaneous tissue, or fascia overlying a joint, the procedure is coded to the following body part:
Shoulder is coded to Upper Arm
Elbow is coded to Lower Arm
Wrist is coded to Lower Arm
Hip is coded to Upper Leg
Knee is coded to Lower Leg
Ankle is coded to Foot.
