Neutropenia due to infection

This code represents a decrease in the number of neutrophils in the blood, specifically when the underlying cause is an infectious process. Neutropenia compromises the body's ability to fight off infections, making patients more susceptible to severe illness. It is a hematologic abnormality directly attributable to the presence of an infection.

Use this code when documentation clearly links neutropenia to an active infection, such as sepsis, viral infections (e.g., HIV, influenza), or severe bacterial infections. Supporting documentation should include laboratory results confirming neutropenia and a physician's statement identifying the infection as the etiology. Do not use this code if the neutropenia is due to chemotherapy, radiation, or other non-infectious causes.

• Always code the underlying infection first, followed by this code to indicate the manifestation.
• Distinguish from neutropenia due to other causes (e.g., drug-induced, congenital, cyclic) which have different ICD-10-CM codes.
• Ensure the medical record explicitly states the causal relationship between the infection and the neutropenia.
