High risk heterosexual behavior

This code identifies individuals engaging in heterosexual behaviors that significantly increase their risk of acquiring or transmitting sexually transmitted infections (STIs), including HIV. It indicates a patient's lifestyle choice or circumstance that places them at elevated risk for adverse health outcomes related to sexual activity.

Use this code when documenting a patient's risk factor for STIs, particularly during preventive counseling, screening, or when evaluating symptoms that could be related to sexual transmission. It is appropriate for patients who report multiple sexual partners, unprotected sex, or other high-risk heterosexual practices.

• Always use this as a secondary diagnosis, never a primary diagnosis.
• Consider co-reporting with codes for STI screening (e.g., Z11.3, Z11.4) or counseling (e.g., Z71.89).
• Ensure documentation clearly supports the patient's engagement in high-risk heterosexual behavior.
