Assault by airgun discharge, subsequent encounter

This code signifies an injury resulting from an assault involving an airgun, such as a BB gun or pellet gun, during a subsequent encounter for care. This includes follow-up treatment, healing, or addressing complications from the initial injury. The injury could range from superficial wounds to more severe internal damage depending on the impact site and projectile.

Apply this code when a patient presents for ongoing management of an injury previously sustained from an airgun assault. This would include visits for wound care, infection treatment, physical therapy, or surgical follow-up related to the initial incident. It is used after the initial acute phase of treatment.

• Always pair this code with an external cause code indicating the intent (e.g., Y00.XXXA for assault by bodily force, if applicable, or other relevant assault codes).
• Ensure a primary diagnosis code detailing the specific injury (e.g., a fracture, open wound, or internal organ injury) is also reported.
• Verify the encounter type is indeed "subsequent" and not an initial encounter or sequela.
