John is admitted to the hospital with pneumonia due to Pneumocystis carinii. The record indicates that John has AIDS. How will the medical coder report the diagnosis codes on John’s chart?

In John's case, the medical coder uses the ICD-10 code corresponding to Pneumocystis carinii infection secondary to Human Immunodeficiency Virus (HIV) infection, whose code is B20.6.

Explanation:

Medical coders use ICD-10 to establish the diagnostic coding of diseases. ICD-10 corresponds to International Statistical Classification of Diseases and Related Health Problems, a system proposed by the world health organization, that covers all possible clinical diagnoses of diseases in codes.

B20 in ICD-10 refers to the manifestation of HIV disease resulting in infectious and parasitic diseases.

Pneumocystis jirovecii pneumonia -previously P. carini pneumonia- is an opportunistic systemic fungal disease that occurs in people with immunodeficiencies, and its HIV-related code is B20.6.
