Z92.85Personal history of cellular therapy

Z92.85 is the ICD-10-CM diagnosis code for personal history of cellular therapy. It belongs to category Z92 (personal history of medical treatment), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) and chapter 21 (factors influencing health status and contact with health services). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within Z92.8 (personal history of other medical treatment), Z92.85 is specifically for personal history of cellular therapy. Related codes cover personal history of extracorporeal membrane oxygenation (ECMO) (Z92.81), status post administration of tPA (rtPA) in a different facility within the last 24 hours prior to admission to current facility (Z92.82), personal history of failed moderate sedation (Z92.83), personal history of unintended awareness under general anesthesia (Z92.84), personal history of gene therapy (Z92.86) and personal history of other medical treatment (Z92.89).

To report this condition, pick the subcode that matches the documentation: Z92.850 (therapy), Z92.858 (therapy) and Z92.859 (unspecified).

The conditions in its Excludes2 note aren't part of Z92.85, but may be coded alongside it if the patient has both: personal history of immune checkpoint inhibitor therapy (Z92.26).

It was added in FY2022, effective October 1, 2021.
