Sprain of other parts of lumbar spine and pelvis, sequela

This code signifies a sprain affecting areas of the lumbar spine or pelvis not specified by more granular codes, presenting as a long-term consequence or late effect of an initial injury. It indicates that the acute phase of the sprain has passed, and the patient is experiencing residual symptoms or complications directly attributable to the original sprain.

Apply this code when documenting a patient's current condition that is a sequela of a previously sustained sprain to an unspecified or "other" part of the lumbar spine or pelvis. This is appropriate for chronic pain, instability, or functional limitations that persist after the initial healing period of such an injury. It should be used when the original injury is no longer acute but continues to impact the patient.

• Always use this code as a secondary diagnosis, following a code for the current presenting symptom or condition.
• Ensure documentation clearly links the current sequela to a past sprain of the lumbar spine or pelvis.
• Verify that the specific anatomical site of the sprain is not better described by a more precise code within the S33 category.
