Valgus deformity, not elsewhere classified, right knee

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

An abnormal outward bending or angling of the right knee joint, where the knee deviates away from the body's midline (knock-knee appearance).

Coding Tips

  • •Confirm right knee is the affected site in clinical documentation
  • •Distinguish from genu valgum due to other causes like rickets or post-traumatic changes
