Personal risk factor of exposure to diethylstilbestrol

This code identifies a patient who has a documented history of exposure to diethylstilbestrol (DES). This exposure can be direct (the patient themselves took DES) or indirect (the patient's mother took DES during pregnancy, leading to in utero exposure). DES is a synthetic estrogen that was prescribed to pregnant women between 1940 and 1971.

Use this code when a patient presents with a history of DES exposure, regardless of whether they are currently experiencing related health issues. This is particularly relevant for patients undergoing screening or evaluation for conditions known to be associated with DES exposure, such as certain reproductive tract abnormalities, cancers (e.g., clear cell adenocarcinoma of the vagina or cervix), or infertility.

• Always document the specific type of DES exposure (direct or in utero) if known.
• This code is for a personal history of exposure; do not use for family history of DES exposure.
• Code any current conditions or complications related to DES exposure in addition to this code.
