Answer :
The root operation for percutaneous irrigation of the knee joint is likely 'irrigation.' The exact ICD-10-PCS code would need to be looked up in the ICD-10-PCS reference book or consulted with a certified medical coder.
The root operation in the case of a 57-year-old patient with percutaneous irrigation of the knee joint refers to the principal purpose of the procedure. In this case, the root operation is most likely irrigation, which is the flushing or washing out of an organ or wound with a specified solution. The ICD-10-PCS code for this procedure would be determined by consulting the current ICD-10-PCS reference book or database, specific to the body part, approach, device, and substance involved. However, as this response is confined to general assistance without access to specific coding databases, it would be advisable to consult the most recent ICD-10-PCS guidelines or a certified medical coder for the exact code for the procedure.
