Wheelchair (powered) colliding w stationary object, init

This code describes an injury or adverse event occurring when a motorized wheelchair strikes an unmoving object. It specifically indicates the initial phase of treatment for such an incident. The collision could involve anything from a wall to furniture or a curb.

Apply this code when a patient presents with an injury directly resulting from their powered wheelchair hitting a stationary object. This is appropriate for the emergency department visit, initial physician consultation, or first hospitalization related to the incident. It should be used in conjunction with codes for the specific injuries sustained.

• Always sequence this external cause code after the primary diagnosis code for the injury.
• Ensure the "A" seventh character is used only for the initial encounter for treatment of the injury.
• Distinguish from collisions with moving objects or non-powered wheelchairs.
