Herpetic gingivostomatitis

This code represents an acute, painful viral infection of the mouth and gums caused by the herpes simplex virus. It typically manifests with vesicles, ulcers, and inflammation of the oral mucosa, often accompanied by fever and malaise.

Use this code when documentation clearly indicates a diagnosis of herpetic gingivostomatitis, often seen in young children during their primary herpes simplex infection. Supporting documentation would include physician notes detailing oral lesions, gingival inflammation, and systemic symptoms consistent with a viral etiology.

• Differentiate from aphthous stomatitis, which is not viral in origin.
• Consider additional codes for any associated systemic manifestations, such as dehydration due to poor oral intake.
• Ensure the documentation specifies "herpetic" to distinguish from other forms of gingivostomatitis.
