About GZJZZZZ

GZJZZZZ is the ICD-10-PCS code for a light therapy procedure on the none using a none approach with none (qualifier: none). In ICD-10-PCS, light therapy means application of specialized light treatments to improve functioning or well-being.

In plain terms, this corresponds to other psychiatric somatotherapy, the ICD-9-CM procedure title it maps to (94.29).

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.
