Mess hall on military base as place

This code identifies a military mess hall as the specific location where an external cause of injury or other adverse event occurred. It provides granular detail about the environment of an incident that led to a patient's condition, rather than describing the condition itself.

Apply this code when documenting an injury, poisoning, or other external cause that took place within the confines of a mess hall situated on a military installation. Examples include slips, falls, burns, or food-related incidents that occur during meal service or other activities within this specific setting.

• Always use this as a secondary code to provide context for an external cause code (V00-Y99).
• Ensure the medical record explicitly states the incident occurred in a "mess hall" on a "military base."
• Do not use for incidents occurring in other areas of a military base; select the appropriate Y92.1- subcategory.
