Disorders of aromatic amino-acid metabolism

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 8 more specific codes instead:

  • E70.0 Classical phenylketonuria
  • E70.1 Other hyperphenylalaninemias
  • E70.2 Disorders of tyrosine metabolism (also a header)
  • E70.3 Albinism (also a header)
  • E70.4 Disorders of histidine metabolism (also a header)
  • E70.5 Disorders of tryptophan metabolism
  • E70.8 Other disorders of aromatic amino-acid metabolism (also a header)
  • E70.9 Disorder of aromatic amino-acid metabolism, 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.
