About HZ5BZZZ

HZ5BZZZ 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 addictive behavior by behavioral, cognitive, psychoanalytic, psychodynamic or psychophysiological means.

In plain terms, this corresponds to alcohol rehabilitation and drug rehabilitation, the ICD-9-CM procedure titles it maps to (94.61 and 94.64).

For a different body part, codes include HZ50ZZZ (cognitive), HZ51ZZZ (behavioral), HZ52ZZZ (cognitive-behavioral), HZ53ZZZ (12-step), HZ54ZZZ (interpersonal), HZ55ZZZ (interactive) and 6 more.

It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 895 (Alcohol, Drug Abuse or Dependence with Rehabilitation Therapy), under the surgical category “Alcohol, Drug Abuse or Dependence”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
