Neutropenia, unspecified

This code signifies a reduction in the absolute neutrophil count (ANC) in the blood, where the specific cause or type of neutropenia has not been identified or documented. Neutrophils are a type of white blood cell crucial for fighting bacterial and fungal infections. An unspecified neutropenia indicates a general decrease without further diagnostic clarity.

Use this code when the medical record clearly indicates neutropenia, but the physician has not specified the underlying etiology (e.g., drug-induced, congenital, cyclic). This code is appropriate when documentation only states "neutropenia" without further detail. It should be used when a more specific code for neutropenia cannot be assigned due to lack of information.

• Avoid using this code if a more specific type of neutropenia is documented (e.g., congenital, drug-induced, cyclic).
• Query the provider for further specificity if the documentation mentions neutropenia but lacks details on its cause or type.
• Always review the complete medical record to ensure no further information regarding the type or cause of neutropenia is available before assigning this unspecified code.
