About GZ54ZZZ

GZ54ZZZ is the ICD-10-PCS code for a individual psychotherapy procedure on the psychoanalysis using a none approach with none (qualifier: none). In ICD-10-PCS, individual psychotherapy means treatment of an individual with a mental health disorder by behavioral, cognitive, psychoanalytic, psychodynamic or psychophysiological means to improve functioning or well-being.

In plain terms, this corresponds to Psychoanalysis, the ICD-9-CM procedure title it maps to (94.31).

For a different body part, codes include GZ50ZZZ (interactive), GZ51ZZZ (behavioral), GZ52ZZZ (cognitive), GZ53ZZZ (interpersonal), GZ55ZZZ (psychodynamic), GZ56ZZZ (supportive) and 2 more.

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.
