By following the coding guidelines provided below, ICD-10 coding for HIV and AIDS will be much easier.
Question: Patient is diagnosed with symptomatic HIV. What ICD-10-CM code is reported?
According to the ICD-10-CM Official Guidelines for Coding and Reporting, a diagnosis of HIV must be confirmed in order to code for it. Also, once a patient has symptomatic HIV, B20 should be assigned, whether the patient is currently exhibiting symptoms or not. Once a patient has been diagnosed with HIV and displays symptoms of an HIV-related condition, B20 should be assigned to every subsequent admission/encounter.
In the ICD-10-CM Alphabetic Index, see HIV, B20. You can also look under Human Immunodeficiency virus (HIV) disease, (infection), B20.
Verifying this code in the Tabular, B20 refers to Human immunodeficiency virus [HIV] disease. This code includes: acquired immune deficiency syndrome [AIDS]; AIDS-related complex [ARC]; and HIV infection, symptomatic.
Be sure to read all the information at B20 under “Code first,” “Use additional code(s)…,” and “Excludes1” notes.
