In simple words: This code means the person had contact with or was possibly exposed to the HIV virus.It's used even if they don't have symptoms or a confirmed infection.Doctors use this code along with other codes to describe any tests or treatments given.

This ICD-10-CM code signifies contact with or suspected exposure to the human immunodeficiency virus (HIV).It is used when a patient has had potential exposure to HIV, regardless of whether they show symptoms or have a confirmed infection. This code should be used in conjunction with other appropriate codes describing any tests performed or treatment administered.The code excludes asymptomatic HIV infection and should not be used if the patient's HIV status is known.

Example 1: A healthcare worker experiences a needlestick injury from a patient with known HIV.Z20.6 is used to document the exposure, along with codes for the needlestick injury and any PEP administered., An individual reports sexual contact with a person who has HIV. Z20.6 would be used to document the potential exposure, and HIV testing codes would be added based on the test results., A traveler returns from a region with a high prevalence of HIV and seeks testing. Z20.6 would be used alongside codes for the HIV tests performed to document the encounter.

Thorough documentation should include details of the potential exposure (date, time, nature of contact), the source of exposure (if known), results of any diagnostic tests (e.g., HIV antibody tests), any counseling or preventative measures provided, and complete documentation of medical decision-making and treatment plan.

** Z20.6 is not a billable code in itself. It requires a corresponding procedure code if any procedures are performed (e.g., HIV testing or PEP administration).The selection of additional codes depends entirely on the clinical circumstances of the encounter and any services rendered.
