Need for prophylactic vaccination and inoculation against smallpox

This code signifies an encounter for the purpose of receiving a smallpox vaccine or inoculation for preventive health. It indicates that the patient is seeking protection against the variola virus, which causes smallpox.

This code is used when a patient presents for smallpox vaccination, often in the context of occupational exposure (e.g., laboratory personnel handling variola virus) or military personnel deployment to areas with potential biological threats. It may also be used for individuals identified as contacts during a smallpox outbreak, though such scenarios are extremely rare given smallpox eradication.

• This code is for the need for vaccination, not for an adverse reaction or complication from a smallpox vaccine.
• Always sequence this code as a primary diagnosis when the sole reason for the encounter is the prophylactic vaccination.
• Ensure documentation clearly states the purpose of the visit is for smallpox prevention.
