Postauricular fistula, unspecified ear

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 forms behind the ear, typically resulting from infection or inflammation of the mastoid bone. This condition allows drainage or fluid to leak from the area behind the ear.

Coding Tips

  • •Verify documentation specifies the fistula is postauricular (behind the ear) rather than other ear locations to ensure correct code selection
  • •If the specific ear (right, left, or bilateral) is documented, use the more specific codes H70.811 or H70.812 instead of the unspecified code H70.819
