Inguinal hernia

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 6 more specific codes instead:

  • K40.0 Bilateral inguinal hernia, with obstruction, without gangrene (also a header)
  • K40.1 Bilateral inguinal hernia, with gangrene (also a header)
  • K40.2 Bilateral inguinal hernia, without obstruction or gangrene (also a header)
  • K40.3 Unilateral inguinal hernia, with obstruction, without gangrene (also a header)
  • K40.4 Unilateral inguinal hernia, with gangrene (also a header)
  • K40.9 Unilateral inguinal hernia, without obstruction or gangrene (also a header)

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.
