D89.8

Other specified 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 5 more specific codes instead:

  • D89.81 Graft-versus-host disease (also a header)
  • D89.82 Autoimmune lymphoproliferative syndrome [ALPS]
  • D89.83 Cytokine release syndrome (also a header)
  • D89.84 IgG4-related disease
  • D89.89 Other specified disorders involving the immune mechanism, not elsewhere classified

What has happened to this code

Every change the publisher made, from 2007 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.

  1. FY2007 Added to the draft code set draft Other specified disorders involving the immune mechanism, not elsewhere classified
  2. FY2010 Removed from the draft draft
  3. FY2012 Returned to the draft draft

Official coding rules

Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.
