Other specified infectious and parasitic diseases

This code identifies infectious or parasitic diseases that are not classified elsewhere within the ICD-9-CM framework but are specifically documented by a clinician. It serves as a residual category for rare or unusual infectious conditions that have a definitive diagnosis but lack a more precise code.

Apply this code when the medical record clearly states a specific infectious or parasitic disease that does not have its own unique ICD-9-CM code. Examples include certain rare tropical infections, newly identified infectious agents without a dedicated code, or highly specific parasitic infestations not otherwise categorized. Documentation must explicitly name the condition.

• Avoid using this code as a default for unspecified infections; always seek a more specific code first.
• Ensure the documentation clearly identifies the specific infectious or parasitic disease, not just a general infection.
• Review the entire chapter for more precise codes before resorting to this residual category.
