Other specified viral diseases

This code identifies viral infections that are not specifically classified elsewhere in the ICD-10-CM system. It is used for viral diseases that have been definitively diagnosed but do not have a more precise code available.

Apply this code when documentation clearly states a viral etiology for a condition that lacks a specific ICD-10-CM code. This includes rare viral infections or viral conditions with atypical presentations not covered by more specific codes. Ensure the medical record explicitly identifies the condition as viral.

• Do not use this code if a more specific viral disease code exists (e.g., influenza, herpes simplex).
• Carefully review the "Excludes1" notes to avoid inappropriate co-coding with HPV infections.
• Documentation must clearly state the viral nature of the disease; avoid using for suspected but unconfirmed viral conditions.
