Other specified events, undetermined intent, subs encntr

This code signifies an injury or adverse event where the intent (accidental, self-harm, assault) cannot be determined, and the specific external cause is known but doesn't fit into more precise categories. It's used when the circumstances surrounding the event remain ambiguous after investigation.

Apply this code for follow-up care of injuries where the provider explicitly documents "undetermined intent" and the external cause is specified (e.g., "fall, undetermined intent"). This is appropriate for subsequent visits related to the initial injury, such as wound checks, physical therapy, or medication management.

• Always ensure the "D" (subsequent encounter) seventh character is appropriate for the patient's visit.
• Pair this code with an injury code (e.g., fracture, laceration) to fully describe the patient's condition.
• Only use when documentation explicitly states "undetermined intent" and a more specific external cause code is not applicable.
