Mumps (B26)

The ICD-10 code for mumps is B26, covering the viral infection known as mumps and its various complications. These codes help specify whether the infection is uncomplicated or involves particular organs or conditions.

The base code B26 represents mumps generally, while detailed codes like B26.0 identify mumps orchitis (also called infective orchitis), inflammation of the testes caused by the mumps virus. B26.1 and B26.2 correspond to neurological complications such as mumps meningitis and mumps encephalitis (including meningoencephalitis), resulting from Paramyxovirus infection. Other specified complications include mumps pancreatitis (B26.3), hepatitis (B26.81), myocarditis (B26.82), nephritis (B26.83), polyneuropathy (B26.84), and arthritis (B26.85). The code B26.89 covers less common complications like infectious sialoadenitis of salivary glands and oophoritis. Finally, B26.9 is used for mumps without complications, encompassing parotitis and sialadenitis of related glands. Using the correct code ensures precise classification of mumps cases and their specific manifestations.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Measles-Mumps-Rubella Vaccine

A combined vaccine used to prevent MEASLES; MUMPS; and RUBELLA.

Mumps

An acute infectious disease caused by RUBULAVIRUS, spread by direct contact, airborne droplet nuclei, fomites contaminated by infectious saliva, and perhaps urine, and usually seen in children under the age of 15, although adults may also be affected. (From Dorland, 28th ed)

Mumps Vaccine

Vaccines used to prevent infection by MUMPS VIRUS. Best known is the live attenuated virus vaccine of chick embryo origin, used for routine immunization of children and for immunization of adolescents and adults who have not had mumps or been immunized with live mumps vaccine. Children are usually immunized with measles-mumps-rubella combination vaccine.

Mumps virus

The type species of RUBULAVIRUS that causes an acute infectious disease in humans, affecting mainly children. Transmission occurs by droplet infection.

Parotitis

INFLAMMATION of the PAROTID GLAND.

Rubulavirus

A genus of the family PARAMYXOVIRIDAE (subfamily PARAMYXOVIRINAE) where all the species have hemagglutinin and neuraminidase activities but lack a C protein. MUMPS VIRUS is the type species.

Viral Fusion Proteins

Proteins, usually glycoproteins, found in the viral envelopes of a variety of viruses. They promote cell membrane fusion and thereby may function in the uptake of the virus by cells.
