About GZ13ZZZ

GZ13ZZZ is the ICD-10-PCS code for a psychological tests procedure on the neuropsychological using a none approach with none (qualifier: none). In ICD-10-PCS, psychological tests means the administration and interpretation of standardized psychological tests and measurement instruments for the assessment of psychological function.

In plain terms, this corresponds to administration of psychologic test, the ICD-9-CM procedure title it maps to (94.02).

For a different body part, codes include GZ10ZZZ (developmental), GZ11ZZZ (personality and behavioral), GZ12ZZZ (intellectual and psychoeducational) and GZ14ZZZ (neurobehavioral and cognitive status).

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.
