Q.    Can you please advise which ICD-10 codes should be assigned to the mother’s episode of care when a baby is delivered by elective caesarean, because the mother has been diagnosed with HIV?

A.    If the patient is asymptomatic HIV positive, and the HIV is not causing any current medical problems, then the appropriate ICD-10 codes are:

O82.0 Delivery by elective caesarean section

Z37.0 Single live birth

Z21.X Asymptomatic human immunodeficiency virus [HIV] infection status

However if, the patient is suffering from active HIV and this is causing associated medical problems, then the appropriate ICD-10 codes are:

O82.0    Delivery by elective caesarean section

Z37.0    Single live birth

B20-B24 Human immunodeficiency virus [HIV] disease (plus any associated problems, including asterisk codes where necessary).

Note: Human immunodeficiency virus [HIV] disease (B20-B24) is referred to at the Exclusion Note at ICD-10 category O98.- Maternal infectious and parasitic diseases classifiable elsewhere but complicating pregnancy, childbirth and the puerperium.
