ICD-10: B26.82

Mumps myocarditis is a rare but serious complication associated with mumps infection, which is primarily known for causing parotitis (inflammation of the parotid glands). The ICD-10-CM code for mumps myocarditis is B26.82. Below is a detailed clinical description and relevant information regarding this condition.

Overview of Mumps

Mumps is a viral infection caused by the mumps virus, which is part of the Paramyxoviridae family. It is characterized by swelling of the salivary glands, particularly the parotid glands, and can lead to various complications, including orchitis, meningitis, and myocarditis. The disease is preventable through vaccination, with the MMR (measles, mumps, rubella) vaccine being the most common method of prevention.

Clinical Description of Mumps Myocarditis

Pathophysiology

Mumps myocarditis occurs when the mumps virus infects the heart muscle (myocardium), leading to inflammation. This can result from direct viral invasion or an autoimmune response triggered by the infection. The inflammation can impair the heart's ability to pump blood effectively, potentially leading to heart failure or arrhythmias.

Symptoms

Patients with mumps myocarditis may present with a variety of symptoms, which can include:

• Chest pain: Often described as a sharp or pressure-like sensation.
• Shortness of breath: This may occur during exertion or at rest.
• Palpitations: Patients may feel an irregular heartbeat or a racing heart.
• Fatigue: Generalized weakness and tiredness are common.
• Fever: A mild fever may accompany other symptoms.

Diagnosis

Diagnosis of mumps myocarditis typically involves:

• Clinical evaluation: A thorough history and physical examination, focusing on symptoms and potential exposure to mumps.
• Laboratory tests: Serological tests to detect mumps virus-specific IgM and IgG antibodies can confirm recent infection.
• Electrocardiogram (ECG): This may show signs of myocarditis, such as ST segment changes or arrhythmias.
• Echocardiogram: Imaging can assess heart function and structure, revealing any abnormalities in the myocardium.
• Cardiac MRI: This may be used for a more detailed evaluation of myocardial inflammation.

Treatment

Management of mumps myocarditis is primarily supportive and may include:

• Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief and inflammation reduction. In severe cases, corticosteroids may be considered.
• Monitoring: Close observation of cardiac function, especially in severe cases or those with significant symptoms.
• Hospitalization: May be required for patients with severe symptoms or complications, such as heart failure.

Prognosis

The prognosis for mumps myocarditis varies. Many patients recover fully with appropriate management, but some may experience long-term cardiac complications. Early recognition and treatment are crucial for improving outcomes.

Conclusion

Mumps myocarditis, coded as B26.82 in the ICD-10-CM, is a serious complication of mumps infection that requires prompt diagnosis and management. Awareness of this condition is essential for healthcare providers, especially in populations where mumps vaccination rates are low. Vaccination remains the most effective strategy for preventing mumps and its associated complications, including myocarditis.
