Late effect of unspecified injury

This code signifies a health problem that arises long after an initial, unspecified injury has healed. It's used when the original cause of the injury is unknown or not documented, but its lasting impact on the patient's health is evident. This represents a residual condition or complication directly attributable to a past, unidentifiable traumatic event.

Apply this code when a patient presents with a chronic or delayed sequela of an injury, and the specific nature or cause of the original injury cannot be determined from the medical record. Documentation should clearly link the current condition to a prior injury, even if the details of that injury are vague or absent. This code is appropriate when more specific late effect codes are not supported.

• Always attempt to identify a more specific late effect code if the original injury is known and documented.
• This code should be sequenced after the code for the specific residual condition being treated.
• Avoid using this code if the original injury is still active or if a more specific "late effect of..." code exists for the documented injury type.
