2025 ICD-10-CM code W28
(Active) Effective Date: N/A External causes of morbidity - Exposure to inanimate mechanical forces (W20-W49) 20 Feed
Contact with powered lawn mower.
The code W28 can be used with 7th character extensions: A (initial encounter), D (subsequent encounter), and S (sequela).These extensions provide additional information about the encounter and should be used when applicable.
The medical necessity is established by the nature and severity of the injury resulting from the contact with the powered lawnmower. The documentation must support the diagnosis and any associated procedures performed.
The clinical responsibility for this code includes documenting the details of the event leading to the injury. This could involve evaluating and managing injuries resulting from the contact, ordering any necessary imaging or lab tests, and potentially consulting with specialists depending on the severity and nature of the injury.
In simple words: Injury or other health condition due to contact with a powered lawnmower.
Contact with powered lawn mower (commercial) (residential).
Example 1: A patient presents to the emergency room with a laceration to the lower leg after accidentally coming into contact with a running lawnmower while mowing the yard. The appropriate ICD-10-CM code W28, along with a code for the laceration, would be assigned., A child is playing in the yard when a neighbor's lawnmower throws a rock, striking the child and causing a contusion.W28 would be used to indicate the cause of the injury., A landscaper is working with a commercial-grade riding lawnmower when they lose control on a slope and are thrown from the mower, sustaining multiple fractures. W28, along with codes for the specific fractures, would be reported.
Documentation should include detailed circumstances surrounding the event, the body part(s) affected, and the nature of the injury sustained.If any treatment was provided at the scene, it should also be documented. It’s crucial to distinguish between contact with a powered and a non-powered lawnmower.
** While there is no national mandate, reporting of external cause codes like W28 is encouraged for injury research and prevention efforts. Remember to check state-specific or payer requirements.
