ICD-10-CM Code B05


Version 2021 Non-Billable Code

Not Valid for Submission

B05 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of measles. The code is NOT valid for the year 2021 for the submission of HIPAA-covered transactions.

Short Description:Measles
Long Description:Measles

Consider the following ICD-10 codes with a higher level of specificity:

  • B05.0 - Measles complicated by encephalitis
  • B05.1 - Measles complicated by meningitis
  • B05.2 - Measles complicated by pneumonia
  • B05.3 - Measles complicated by otitis media
  • B05.4 - Measles with intestinal complications
  • B05.8 - Measles with other complications
  • B05.81 - Measles keratitis and keratoconjunctivitis
  • B05.89 - Other measles complications
  • B05.9 - Measles without complication

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code B05:


This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • subacute sclerosing panencephalitis A81.1

Clinical Information

  • MEASLES-. a highly contagious infectious disease caused by morbillivirus common among children but also seen in the nonimmune of any age in which the virus enters the respiratory tract via droplet nuclei and multiplies in the epithelial cells spreading throughout the mononuclear phagocyte system.
  • MEASLES VACCINE-. a 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 measles or been immunized with live measles vaccine and have no serum antibodies against measles. children are usually immunized with measles mumps rubella combination vaccine. from dorland 28th ed
  • MEASLES VIRUS-. the type species of morbillivirus and the cause of the highly infectious human disease measles which affects mostly children.
  • RUBELLA-. an acute infectious disease caused by the rubella virus. the virus enters the respiratory tract via airborne droplet and spreads to the lymphatic system.
  • RUBELLA VIRUS-. the type and only species of rubivirus causing acute infection in humans primarily children and young adults. humans are the only natural host. a live attenuated vaccine is available for prophylaxis.
  • SUBACUTE SCLEROSING PANENCEPHALITIS-. a rare slowly progressive encephalitis caused by chronic infection with the measles virus. the condition occurs primarily in children and young adults approximately 2 8 years after the initial infection. a gradual decline in intellectual abilities and behavioral alterations are followed by progressive myoclonus; muscle spasticity; seizures; dementia; autonomic dysfunction; and ataxia. death usually occurs 1 3 years after disease onset. pathologic features include perivascular cuffing eosinophilic cytoplasmic inclusions neurophagia and fibrous gliosis. it is caused by the sspe virus which is a defective variant of measles virus. from adams et al. principles of neurology 6th ed pp767 8
  • 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.
  • MEASLES MUMPS RUBELLA VACCINE-. a combined vaccine used to prevent measles; mumps; and rubella.

Code Classification

  • Certain infectious and parasitic diseases (A00–B99)
    • Viral infections characterized by skin and mucous membrane lesions (B00-B09)
      • Measles (B05)

Information for Patients


Also called: Rubeola

Measles is an infectious disease caused by a virus. It spreads easily from person to person. It causes a blotchy red rash. The rash often starts on the head and moves down the body. Other symptoms include

  • Fever
  • Cough
  • Runny nose
  • Conjunctivitis (pink eye)
  • Feeling achy and run down
  • Tiny white spots inside the mouth

Sometimes measles can lead to serious problems. There is no treatment for measles, but the measles-mumps-rubella (MMR) vaccine can prevent it.

"German measles", also known as rubella, is a completely different illness.
