Need for prophylactic vaccination and inoculation against measles-mumps-rubella (MMR)

This code indicates a patient's requirement for preventive immunization against measles, mumps, and rubella. It signifies that the individual is due for or is receiving the combined MMR vaccine to establish immunity against these three common childhood viral diseases.

This code is appropriate for encounters where a patient presents for routine MMR vaccination, booster doses, or catch-up immunizations according to recommended schedules. It is also used when documenting the need for MMR prophylaxis in susceptible individuals, such as prior to international travel or in healthcare settings.

• Always sequence this code as a secondary diagnosis when administered during a well-child visit or other primary care encounter.
• Ensure proper sequencing with a procedure code for the administration of the vaccine (e.g., CPT code 90471-90474 for vaccine administration).
• Do not use this code if the patient is presenting with an active measles, mumps, or rubella infection; instead, code the specific infectious disease.
