Fall from or off toilet w/o strike against object, subs

This code describes an injury resulting from a patient falling from or off a toilet, where the fall itself was the sole mechanism of injury without the patient striking another object afterward. This specific code is for a subsequent encounter, indicating the patient is receiving follow-up care for an injury sustained during such an event.

Use this code for follow-up visits related to injuries (e.g., sprains, contusions, minor fractures) sustained when a patient fell off a toilet without hitting anything else. This applies when the initial injury has already been treated and the patient is returning for ongoing management, monitoring, or rehabilitation.

• Always assign an external cause code (W18.11XD) in conjunction with an injury code.
• Ensure the encounter is truly "subsequent" and not the initial treatment for the injury.
• Verify documentation explicitly states the fall was from a toilet and no other object was struck.
