Contact with knife, undetermined intent, sequela

This code signifies a long-term consequence or complication arising from an injury involving a knife where the intent (accidental, self-harm, assault) could not be determined at the time of the original injury. It is used to report conditions that are residual effects of the initial knife contact, manifesting after the acute phase of the injury has passed.

Apply this code when documenting a current condition or symptom that is a direct result of a past, unspecified knife injury. Examples include chronic pain, scarring, nerve damage, or functional limitations directly attributable to the original incident, where the intent of the knife contact was never definitively established.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a previous knife injury with undetermined intent.
• Do not use for acute injuries; this code is exclusively for sequelae.
