Transient synovitis, unspecified 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 in the knee joint when the specific side (left or right) is not documented or specified.

Coding Tips

  • Use this code only when laterality cannot be determined from documentation; query provider if possible for specificity
  • This is a less specific code; bilateral involvement should be coded separately for each side
