About GZC9ZZZ

GZC9ZZZ is the ICD-10-PCS code for a biofeedback procedure on the other biofeedback using a none approach with none (qualifier: none). In ICD-10-PCS, biofeedback means provision of information from the monitoring and regulating of physiological processes in conjunction with cognitive-behavioral techniques to improve patient functioning or well-being.

In plain terms, this corresponds to other individual psychotherapy, the ICD-9-CM procedure title it maps to (94.39).

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.
