ICD 10 code for HIV
ICD 10 Code for HIV (Human Immunodeficiency Virus) is listed below:
HIV – B20
Symptomatic HIV – B20
HIV Positive – Z21
Asymptomatic HIV – Z21
HIV Negative – Z71.7
Code only the confirmed cases
ICD 10 code for HIV should be coded only when it’s confirmed from the provider
For example:
Assume patient admitted for anemia with possible HIV infection
ICD 10 Code for Anemia is D64.9
In the above example we have coded only anemia, as the HIV is not yet confirmed from the physician.
Selection and sequencing – ICD 10 code for HIV
- Patient admitted for HIV related condition
The primary ICD 10 code should be HIV B20 and the secondary diagnoses code is HIV related condition.
Example 1:
HIV with pneumocytosis
ICD 10 code for HIV with pnemocytosis is B20, B59
Example 2:
A patient with AIDS developed Encephalitis as a manifestation of AIDS and is seen in the office for encephalitis
ICD 10 code is B20, G05.3
- HIV Patient admitted for unrelated condition
If HIV patient met with an accident and admits the hospital then it’s an unrelated condition, in this case the primary diagnosis code will be unrelated condition, secondary diagnoses code will HIV(B20) and followed by any HIV related condition. The sequencing of code will be in below order.
- Unrelated condition
- HIV – B20
- HIV related condition
Example 1:
A symptomatic HIV patient is at initial visit for sprained left ankle
ICD 10 code is S93.402A, B20
Example 2:
A 48 year old female patient with HIV is at the subsequent right hip fracture
ICD 10 code is S72.001D, B20
- Asymptomatic HIV- Z21
Asymptomatic means showing no symptoms. If the provider document without any symptoms like HIV positive, known HIV or HIV test positive, then we need to assign the Z21 code.
Example:
Patient admitted with acute appendicitis and positive HIV
ICD 10 code is K35.80, Z21
- Patient with HIV infection during pregnancy, childbirth and the puerperium
In this case, the primary diagnosis code will be always O98.7_, followed by HIV(symptomatic-B20 or asymptomatic-Z21) and HIV related condition.
Example 1:
A pregnant patient in her third trimester at 38 weeks with a symptomatic HIV infection present for check up
ICD 10 code is O98.713, B20, Z3A.38
Example 2:
A pregnant patient in her first trimester (8 weeks) diagnoses with HIV, she has not experiencing HIV related condition.
ICD 10 code is O98.711, Z21, Z3A.08
- Encounter for testing for HIV
ICD 10 code for Encounter for screening is Z11.4
ICD 10 code for counseling code is Z71.7
Example 1:
A 32 year old female patient present and request to do HIV test as she had unprotected test. Provider performs screening test and spent 25 minutes for counseling
ICD 10 code is Z11.4, Z71.7
Example 2:
A 40 year old female patient present for her HIV test result, doctor advise her that HIV is asymptomatic and spent 35 minutes for counseling.
ICD 10 code is Z21, Z71.7
Conclusion: With the above examples we determine how to code the HIV codes when the cases not confirmed, when the patient encounter for HIV testing, when patient with HIV during pregnancy, when HIV patient with unrelated condition.
