Wheelchair (powered) colliding w stationary object, subs

This code describes an injury or adverse event that occurred when a powered wheelchair struck an unmoving object, and the patient is presenting for follow-up care related to that incident. This indicates that the initial treatment for the collision has already been rendered, and the current encounter is for ongoing management, complications, or recovery.

Use this code when a patient returns for a subsequent visit following an injury sustained from their powered wheelchair colliding with a stationary object. This applies to scenarios such as follow-up appointments for wound care, physical therapy, or monitoring of internal injuries that resulted from the initial impact.

• Always pair this external cause code with an injury code describing the specific nature of the patient's injury.
• Ensure the "D" seventh character is used only for subsequent encounters, not for the initial treatment of the injury.
• Verify documentation clearly states the patient is using a powered wheelchair and that the collision was with a stationary object.
