If a patient ever has a symptom due to a HIV infection, only B20 is coded and Z21 should never be coded again, according to the ICD-10-CM Official Guidelines. Suppose a patient with HIV disease is admitted for an unrelated condition such as a fracture. Here, the code for the unrelated condition should be sequenced first.
Diagnosis Index entries containing back-references to Z21: HIV B20 - see also Human, immunodeficiency virus ICD-10-CM Diagnosis Code B20 Human immunodeficiency virus (HIV) disease (infection) B20 ICD-10-CM Diagnosis Code B20 Status (post) - see also Presence (of) human immunodeficiency virus Z21 (HIV)
Code Z21 is used for patients who are asymptomatic, meaning they are HIV positive but have never had an HIV-related condition. Once that patient experiences an HIV-related condition, the Z21 code is no longer appropriate.
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.
ICD 10 code for HIV with pnemocytosis is B20, B59 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
Assign code B20 for all types of HIV infections, which may be described by a variety of terms including: • AIDS. Acquired immune deficiency syndrome. Acquired immunodeficiency syndrome.
ICD-10-CM Code for Human immunodeficiency virus [HIV] disease B20.
B24 Unspecified human immunodeficiency virus [HIV] disease.
Asymptomatic human immunodeficiency virus [HIV] infection status. Z21 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM Z21 became effective on October 1, 2021.
Once a patient is coded to B20, they will always have B20 coded on their record; they will never go back to being coded using the asymptomatic code Z21. Code Z21 is used for patients who are asymptomatic, meaning they are HIV positive but have never had an HIV-related condition.
