Family history of exposure to diethylstilbestrol

This code indicates a patient's family history of exposure to diethylstilbestrol (DES), a synthetic estrogen prescribed to pregnant women between 1938 and 1971. Such exposure, particularly in utero, is associated with various adverse health effects in the exposed individual and their offspring, including reproductive tract abnormalities and certain cancers.

Assign this code when documenting a patient's family history of DES exposure, such as when a patient's mother or grandmother was exposed to DES during pregnancy. This is relevant for risk assessment and monitoring for potential DES-related health complications in the patient.

• This code is for family history, not direct patient exposure.
• Use in conjunction with other codes describing the patient's current health conditions or for screening/preventive services.
• Ensure documentation clearly specifies a family member's DES exposure.
