Personal history of medical treatment (Z92) ICD-10-CM
The Z92 code range covers personal history of medical treatment with 24 ICD-10-CM diagnosis codes. 19 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the Z92 Code Range
These codes describe a person's history of medical treatment, including contraception, drug treatment, radiation treatment, and other types of treatment.
Z92 separates these histories by treatment type. Z92.2 divides drug treatment into specific types, including chemotherapy, estrogen, and steroids. The steroid branch further separates inhaled treatment from treatment that affects the body as a whole. Z92.8 includes histories of cellular therapy, gene therapy, failed moderate sedation, and unintended awareness during general anesthesia. Cellular therapy has separate codes for a named T-cell therapy, other cellular therapy, and unspecified cellular therapy.
