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 2026, 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
The Z92 ICD-10 codes identify patients’ personal history related to various medical treatments they have undergone, from contraception to specialized therapies like chemotherapy. These codes help track past interventions that may affect current care decisions.
Specifically, the ICD-10 code for personal history of contraception, Z92.0, covers previous use of contraceptive methods, including oral contraceptives and devices like intrauterine contraceptive devices (IUCD). Codes such as Z92.21 and Z92.22 document histories of antineoplastic chemotherapy and monoclonal drug therapy, respectively, clarifying prior cancer treatments. The personal history of steroid therapies, including inhaled (Z92.240) and systemic steroids (Z92.241), records important background for risks related to immunosuppression or endocrine effects. Other codes cover histories of immunosuppression, cellular therapies (e.g., Chimeric Antigen Receptor T-cell therapy at Z92.850), gene therapy, radiation exposure (Z92.3), and extracorporeal membrane oxygenation (ECMO) (Z92.81). The extensive range of these codes helps healthcare providers understand previous treatments, such as medication regimens or specialized interventions, that influence ongoing management safely and effectively.
