B26.2 is a billable ICD-10 code used to specify a medical diagnosis of mumps encephalitis. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Encephalitis caused by Rubulavirus
- Meningitis caused by Paramyxovirus
- Meningoencephalitis caused by virus
- Mumps encephalitis
- Mumps meningitis
- Mumps meningoencephalitis
- 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.
- 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.
- 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.

Encephalitis is an inflammation of the brain. Usually the cause is a viral infection, but bacteria can also cause it. It can be mild or severe. Most cases are mild. You may have flu-like symptoms. With a mild case, you may just need rest, plenty of fluids, and a pain reliever.
Severe cases need immediate treatment. Symptoms of severe cases include:
- Severe headache
- Sudden fever
In babies, additional symptoms may include constant crying, poor feeding, body stiffness, and bulging in the soft spots of the skull.
Severe cases may require a stay in the hospital. Treatments include oral and intravenous (IV) medicines to reduce inflammation and treat infection. Patients with breathing difficulties may need artificial respiration. Some people may need physical, speech, and occupational therapy once the illness is under control.

Mumps is an illness caused by the mumps virus. It starts with:
- Muscle aches
- Loss of appetite
After that, the salivary glands under the ears or jaw become swollen and tender. The swelling can be on one or both sides of the face. Symptoms last 7 to 10 days. Serious complications are rare.
You can catch mumps by being with another person who has it. There is no treatment for mumps, but the measles-mumps-rubella (MMR) vaccine can prevent it.
Before the routine vaccination program in the United States, mumps was a common illness in infants, children and young adults. Now it is a rare disease in the U.S.
