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:

  • E23.0 Hypopituitarism
  • E23.1 Drug-induced hypopituitarism
  • E23.2 Diabetes insipidus
  • E23.3 Hypothalamic dysfunction, not elsewhere classified
  • E23.6 Other disorders of pituitary gland
  • E23.7 Disorder of pituitary gland, unspecified

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.
