hat ICD-10 codes are used for total knee replacement?
Total knee replacement, or total knee arthroplasty, is a surgical procedure used to relieve pain and restore function in patients with severe osteoarthritis or other knee joint diseases. After surgery, it's essential to document the presence of artificial knee joints accurately using the appropriate ICD-10-CM codes.
These codes fall under the factors influencing health status and contact with health services. They are used during follow-up care, rehabilitation, and future encounters involving the knee joint. Whether the patient has a right knee replacement, left knee replacement or bilateral total knee arthroplasty replacement, the selected code must reflect the side and the presence of internal prosthetic devices.
Accurate coding supports proper medical billing and documentation and is vital in physical therapy, assessing complications, and continued care planning.
Below are the commonly used ICD-10-CM codes related to the presence of artificial knee joints:
Z96.651 – Presence of right artificial knee joint
Used when a patient has an artificial knee joint on the right side. This means the patient has undergone a surgical procedure known as a total knee replacement (TKR) or knee arthroplasty on the right knee.
Z96.652 – Presence of left artificial knee joint
This code is similar to the previous one but pertains to the left side. It indicates that the patient has an artificial knee joint on the left side resulting from a total knee replacement surgery or knee arthroplasty.
Z96.653 – Presence of artificial knee joint, bilateral
This code is applicable when both knees have been replaced with artificial joints. It documents the presence of bilateral total knee arthroplasty.
Z96.659 – Presence of unspecified artificial knee joint
This is used when documentation does not specify whether the right, left, or bilateral knee was replaced—hence, it represents an unspecified knee. It indicates the presence of a knee joint replacement without side designation.
