Mumps nephritis
ICD-10 B26.83 is a billable code used to indicate a diagnosis of mumps nephritis.
Mumps nephritis is a rare complication of mumps virus infection, characterized by inflammation of the kidneys. The mumps virus, a member of the Paramyxoviridae family, primarily affects the salivary glands but can also lead to systemic complications, including nephritis. Clinically, patients may present with symptoms such as flank pain, hematuria, proteinuria, and renal impairment. Diagnosis is typically confirmed through serological testing for mumps-specific IgM antibodies, which indicate recent infection, and may also include PCR testing of urine or blood samples. Imaging studies, such as ultrasound, may be utilized to assess kidney structure and function. Antiviral treatments for mumps nephritis are limited, as the primary management focuses on supportive care, including hydration and monitoring renal function. In severe cases, corticosteroids may be considered to reduce inflammation. Early recognition and appropriate management are crucial to prevent long-term renal damage.
