Palindromic rheumatism, right knee

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

What This Code Means

A type of arthritis that causes recurring episodes of joint pain and swelling in the right knee that typically resolve completely between flare-ups.

Coding Tips

  • •The knee is a common site for palindromic rheumatism; ensure documentation distinguishes this from other forms of knee arthritis
  • •The fifth character '1' indicates right side; verify laterality is clearly documented before coding
