D89

Other disorders involving the immune mechanism, not elsewhere classified

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 7 more specific codes instead:

  • D89.0 Polyclonal hypergammaglobulinemia
  • D89.1 Cryoglobulinemia
  • D89.2 Hypergammaglobulinemia, unspecified
  • D89.3 Immune reconstitution syndrome
  • D89.4 Mast cell activation syndrome and related disorders (also a header)
  • D89.8 Other specified disorders involving the immune mechanism, not elsewhere classified (also a header)
  • D89.9 Disorder involving the immune mechanism, 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.
