Contact with or exposure to rubella

This code signifies a patient's documented contact with an individual diagnosed with rubella (German measles) or their exposure to the rubella virus. It indicates a potential, rather than confirmed, infection, and is used when the patient themselves does not yet exhibit symptoms or have a confirmed diagnosis of rubella.

Use this code when a patient presents for evaluation after being exposed to rubella, such as a child exposed at school or a pregnant woman exposed in the community. It is appropriate for surveillance or prophylactic care encounters following known exposure, before any signs or symptoms of rubella develop in the exposed individual.

• Do not use this code if the patient has a confirmed diagnosis of rubella; instead, code for the active infection.
• This code is typically a primary diagnosis for exposure encounters, but may be secondary if another condition is being treated concurrently.
• Ensure documentation clearly states exposure to rubella, not just a general viral exposure.
