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:

  • K55.0 Acute vascular disorders of intestine (also a header)
  • K55.1 Chronic vascular disorders of intestine
  • K55.2 Angiodysplasia of colon (also a header)
  • K55.3 Necrotizing enterocolitis (also a header)
  • K55.8 Other vascular disorders of intestine
  • K55.9 Vascular disorder of intestine, unspecified

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.
