B08.5 Enteroviral vesicular pharyngitis

ICD10CM code

#### Name of the Condition
- Enteroviral Vesicular Pharyngitis
- Also known as Herpangina

#### Summary
Enteroviral vesicular pharyngitis, commonly referred to as herpangina, is a viral infection characterized by small, blister-like sores and ulcers in the mouth and throat. It is predominantly seen in young children and can cause significant discomfort.

#### Causes
The condition is caused by enteroviruses, most often the Coxsackie A virus. The virus is spread primarily through oral-fecal routes, respiratory droplets, or direct contact with an infected person.

#### Risk Factors
- Young age, especially children aged 3 to 10 years.
- Close contact settings, such as daycare centers or schools.
- Weakened immune systems, which can make children more susceptible to infection.

#### Symptoms
- Sudden onset of fever.
- Sore throat and painful swallowing.
- Small, painful blisters or ulcers in the back of the mouth and throat.
- Loss of appetite and irritability, particularly in young children.

#### Diagnosis
Diagnosis is primarily based on physical examination of the symptoms and medical history. In some cases, throat swabs or stool samples may be analyzed to identify the specific virus.

#### Treatment Options
- Symptomatic treatment includes pain relievers like ibuprofen or acetaminophen.
- Adequate hydration to prevent dehydration, especially if fever is present.
- In more severe cases, antiviral medications may be considered for managing symptoms.

#### Prognosis and Follow-Up
The prognosis is generally good, with most children recovering fully within a week to ten days. Follow-up care is rarely necessary unless complications arise or symptoms persist.

#### Complications
- Dehydration from low fluid intake due to sore throat.
- Rarely, viral meningitis or encephalitis if the infection spreads to other areas.

#### Lifestyle & Prevention
- Encourage good hygiene practices, such as frequent hand washing.
- Advising against sharing eating utensils or drinks can prevent spreading.
- Isolation of infected individuals, especially during peak symptom periods, can minimize transmission.

#### When to Seek Professional Help
- Seek medical attention if the child shows signs of severe dehydration, high fever, or prolonged symptoms lasting more than ten days.
- Immediate help is needed if complications like neck stiffness, severe headaches, or changes in consciousness occur.

#### Tips for Medical Coders
- Ensure accurate coding by confirming the specificity of symptoms and identification of the virus if known.
- Be cautious not to confuse with similar conditions like hand-foot-and-mouth disease, which may have different ICD codes.
