Measles without complication

This code signifies a confirmed diagnosis of measles (rubeola) where no associated complications, such as pneumonia, encephalitis, or otitis media, are documented. It represents the uncomplicated presentation of the viral infection characterized by fever, cough, coryza, conjunctivitis, and a characteristic maculopapular rash.

Apply this code when the patient's medical record clearly states a diagnosis of measles and explicitly denies or does not mention any secondary infections or sequelae. This is appropriate for cases where the measles infection is the sole clinical finding without any additional, related conditions requiring separate coding.

• Ensure documentation explicitly states "without complication" or similar phrasing, or that no complications are otherwise noted.
• Do not use this code if any measles-related complications (e.g., pneumonia, otitis media, encephalitis) are present; instead, code the specific complication.
• Consider Z20.89 (Contact with and exposure to other communicable diseases) if the patient was exposed but has not developed symptoms.
