2025 ICD-10-CM code Y00
(Active) Effective Date: N/A External causes of morbidity - Assault (X92-Y09) 20. External causes of morbidity (V00-Y99) Feed
Assault by blunt object
This code allows 7th character extensions to indicate the encounter type:A (initial encounter)D (subsequent encounter)S (sequela)
Medical necessity for the treatment of injuries resulting from an assault is established by the nature and severity of the injuries themselves, not the external cause code. This code helps provide context for the event.
Clinicians should use this code as a supplementary code to describe the cause of the injury. The primary code should describe the nature of the injury itself.Accurate documentation of the circumstances surrounding the assault is crucial for proper coding.
- 20. External causes of morbidity (V00-Y99)
- Assault by blunt object (Y00) is part of the Assault block (X92-Y09), which in turn falls under the broader category of External causes of morbidity (V00-Y99).This hierarchical structure is essential for accurate coding and data analysis.
In simple words: This code indicates that a person was injured by being hit with a blunt object during an assault. It's important to note that this code describes the cause of the injury, not the injury itself.A separate code would be used to describe the specific injury, such as a fracture or contusion.
Assault by blunt object.This code describes the circumstance causing an injury, not the nature of the injury itself.
Example 1: A patient presents to the ER with a fractured arm after being attacked with a baseball bat.The code Y00 would be used as a secondary code to indicate the assault with a blunt object, while a separate code would describe the fractured arm., A patient is treated for head trauma after being hit with a rock during a fight. Y00 is used as a secondary code, alongside the code for the head injury, to specify the assault., A victim of domestic violence presents with multiple contusions after being struck with a blunt object.The contusions are coded primarily, with Y00 added as a secondary code to indicate the circumstances of the injury.
Documentation should clearly state that the injury resulted from an assault involving a blunt object. Details about the object, the nature of the assault, and the resulting injuries should be recorded.
