M25.10

Billable

Fistula, unspecified joint

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

What This Code Means

An abnormal tunnel or opening that has formed in a joint, allowing fluid or infection to drain or communicate with surrounding tissues.

Coding Tips

  • •This is a rare condition; verify the diagnosis carefully and ensure it's not being confused with other joint complications
  • •Determine the specific joint location if possible, as more specific codes (M25.11-M25.19) should be used when the site is known
