Herpesviral gingivostomatitis and pharyngotonsillitis
ICD-10 B26.2 is a billable code used to indicate a diagnosis of herpesviral gingivostomatitis and pharyngotonsillitis.
Herpesviral gingivostomatitis and pharyngotonsillitis is primarily caused by the herpes simplex virus (HSV), most commonly HSV type 1. This condition is characterized by inflammation of the gingiva (gums), oral mucosa, and pharynx, leading to painful sores and lesions. Symptoms typically include fever, irritability, difficulty swallowing, and oral pain, which can significantly affect a patient's ability to eat and drink. The lesions may appear as vesicles that rupture to form ulcers, often accompanied by lymphadenopathy. Diagnosis is usually clinical, supported by patient history and physical examination. Laboratory confirmation can be achieved through viral culture, polymerase chain reaction (PCR), or serological tests. Antiviral treatments, such as acyclovir or valacyclovir, are effective in reducing the severity and duration of symptoms, particularly when initiated early in the course of the disease. Supportive care, including hydration and pain management, is also crucial in managing this condition.
Detailed history of symptoms, including onset and duration, and any associated systemic symptoms.
Children presenting with fever, oral lesions, and difficulty swallowing.
Consideration of dehydration risk in young children and the need for supportive care.
Thorough examination findings, including the extent of pharyngeal involvement and any complications.
Adults with severe throat pain and vesicular lesions in the oropharynx.
Documentation of any surgical interventions or complications that may arise.
Used when laboratory confirmation is needed for diagnosis.
Document the reason for testing and any clinical findings.
Ensure that the test is ordered based on clinical suspicion.
The primary cause is the herpes simplex virus, most commonly HSV type 1, which can lead to painful oral lesions and systemic symptoms.
