Other infectious disease

This code signifies an infectious disease that is not specifically classified elsewhere within the ICD-10-CM system. It is used when a definitive infectious agent or condition is identified, but a more precise code is unavailable. This category encompasses a variety of rare or unusual infections that do not fit into existing, more specific classifications.

Use this code when the medical record clearly documents an infectious process for which no other specific ICD-10-CM code exists. This typically occurs with uncommon pathogens or presentations that lack a dedicated code. Documentation should explicitly state the infectious nature of the condition and rule out more specific diagnoses.

• Always attempt to find a more specific infectious disease code before resorting to this residual category.
• Ensure documentation clearly supports an infectious etiology; avoid using this code for non-infectious conditions.
• Consider sequencing this code as a secondary diagnosis if the primary condition is a manifestation of the "other infectious disease."
