About GZB4ZZZ
GZB4ZZZ is the ICD-10-PCS code for a electroconvulsive therapy procedure on the other electroconvulsive therapy using a none approach with none (qualifier: none). In ICD-10-PCS, electroconvulsive therapy means the application of controlled electrical voltages to treat a mental health disorder.
In plain terms, this corresponds to other electroshock therapy, the ICD-9-CM procedure title it maps to (94.27).
For a different body part, codes include GZB0ZZZ (unilateral-single seizure) and GZB2ZZZ (bilateral-single seizure).
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.
