Adenosine deaminase [ADA] deficiency

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

Billable FY2016 to FY2019, and a category header from FY2020.

Submit one of these 4 more specific codes instead:

D81.30 Adenosine deaminase deficiency, unspecified
D81.31 Severe combined immunodeficiency due to adenosine deaminase deficiency
D81.32 Adenosine deaminase 2 deficiency
D81.39 Other adenosine deaminase deficiency

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.

FY2007 Added to the draft code set draft Adenosine deaminase [ADA] deficiency
FY2020 Stopped being billable
