Assault by oth gas, air or spring-operated gun, subs encntr

This code signifies an injury sustained from an assault involving a gas, air, or spring-operated gun, such as a BB gun or pellet gun, when the patient is receiving follow-up care after the initial treatment. This includes complications, healing, or ongoing management related to the original incident.

Apply this code when a patient presents for a subsequent visit following an assault by a non-firearm projectile weapon powered by gas, air, or a spring mechanism. This could include wound checks, infection management, or physical therapy related to the initial injury. It is appropriate for any encounter after the initial emergency room visit or hospitalization for the acute injury.

• Always sequence this code after the primary injury code (e.g., foreign body in soft tissue, open wound).
• Ensure the documentation clearly indicates the mechanism of injury was an assault by a non-powder firearm.
• Verify that the encounter is for follow-up care, not the initial treatment, to correctly apply the "D" seventh character.
