About coding HIV contact
The ICD-10-CM code for HIV contact is Z20.6 (Contact with and (suspected) exposure to human immunodeficiency virus [HIV]).
Within Z20 (contact with and (suspected) exposure to communicable diseases), Z20.6 is specifically for contact with and (suspected) exposure to human immunodeficiency virus [HIV]. Related codes cover intestinal infectious diseases (Z20.0), tuberculosis (Z20.1), infections with a predominantly sexual mode of transmission (Z20.2), rabies (Z20.3), rubella (Z20.4), viral hepatitis (Z20.5), pediculosis, acariasis and other infestations (Z20.7), other communicable diseases (Z20.8) and 1 more.
Don't report Z20.6 together with the conditions in its Excludes1 note: asymptomatic human immunodeficiency virus [HIV] and HIV infection status (Z21).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for Z20.6)
- asymptomatic human immunodeficiency virus [HIV]
- HIV infection status (Z21)
