About HZ2ZZZZ

HZ2ZZZZ is the ICD-10-PCS code for a detoxification services procedure on the none using a none approach with none (qualifier: none). In ICD-10-PCS, detoxification services means detoxification from alcohol and/or drugs.

In plain terms, this corresponds to alcohol detoxification and drug detoxification, the ICD-9-CM procedure titles it maps to (94.62 and 94.65).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
