Transient synovitis, right knee

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

What This Code Means

Temporary inflammation of the fluid-filled sac (synovium) in the right knee joint, usually self-limiting and resolving within weeks.

Coding Tips

  • •Transient synovitis is often called 'toxic synovitis' and is common in children; document the affected side clearly
  • •This condition typically resolves spontaneously; if symptoms persist beyond 2-3 weeks, consider alternative diagnoses
