Unspecified injury of lower back, sequela

This code signifies a long-term or late-effect condition resulting from a previously sustained, but unspecified, injury to the lower back. It indicates that the original injury's acute phase has passed, and the patient is now experiencing residual symptoms or complications directly attributable to that past trauma. The specific nature of the initial lower back injury is not documented or is unknown.

Use this code when a patient presents with ongoing symptoms (e.g., chronic pain, limited mobility, neurological deficits) in the lower back that are clearly linked to an old, unidentifiable injury. This is appropriate for follow-up encounters where the primary focus is managing the sequelae of a past, uncharacterized lower back trauma.

• Always sequence this code after the code(s) for the specific residual condition(s) being treated.
• Ensure documentation clearly states the current condition is a "sequela" or "late effect" of a past injury.
• Avoid using this code if the original injury is known and a more specific sequela code exists for that particular injury type.
