Measles, unspecified
ICD-10 B05.9 is a billable code used to indicate a diagnosis of measles, unspecified.
Measles, also known as rubeola, is a highly contagious viral infection characterized by a distinctive rash, fever, cough, and conjunctivitis. The measles virus is transmitted through respiratory droplets and can remain infectious on surfaces for several hours. The incubation period for measles is typically 10 to 14 days, with the onset of symptoms often beginning with a high fever, followed by the appearance of Koplik spots in the mouth, and subsequently a maculopapular rash that usually starts on the face and spreads downward. Complications can arise, particularly in young children and immunocompromised individuals, including diarrhea, otitis media, and pneumonia. Severe complications such as encephalitis and subacute sclerosing panencephalitis (SSPE) can occur, leading to long-term neurological damage. Vaccination with the measles, mumps, and rubella (MMR) vaccine is the most effective preventive measure, and it is recommended for children at 12-15 months of age, with a second dose at 4-6 years. Despite the availability of a vaccine, outbreaks can occur, particularly in unvaccinated populations, making awareness and accurate coding essential for public health monitoring.
Documentation should include vaccination history, clinical symptoms, and any complications observed.
Pediatric patients presenting with fever and rash, suspected measles exposure, or confirmed measles cases.
Special attention should be given to the vaccination status of the child and any potential exposure history.
Detailed clinical notes on the patient's history, laboratory results, and any complications should be documented.
Patients with confirmed measles infection, particularly those with severe complications or co-morbidities.
Consideration of differential diagnoses and the need for additional testing to confirm measles.
When administering the MMR vaccine to a child.
Document the vaccine administered, date, and patient consent.
Pediatric practices should ensure proper documentation of vaccination history.
Document the clinical symptoms, vaccination history, and any relevant exposure history to support the diagnosis of measles.
