About GZ3ZZZZ

GZ3ZZZZ is the ICD-10-PCS code for a medication management procedure on the none using a none approach with none (qualifier: none). In ICD-10-PCS, medication management means monitoring and adjusting the use of medications for the treatment of a mental health disorder.

In plain terms, this corresponds to other psychiatric drug therapy, the ICD-9-CM procedure title it maps to (94.25).

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.
