Dislocation of L3/L4 lumbar vertebra, subsequent encounter

This code signifies a dislocation between the third and fourth lumbar vertebrae that has been previously treated and the patient is now presenting for follow-up care, such as cast change, removal of external fixation, or medication adjustment. It indicates an ongoing management phase for an injury that has already received initial definitive treatment.

Apply this code for patients presenting for any encounter following the initial treatment of an L3/L4 lumbar dislocation. This includes follow-up visits for monitoring healing, physical therapy, or addressing complications that arise after the acute phase. Do not use for the initial treatment of the dislocation.

• Ensure documentation specifies L3/L4 dislocation and not another lumbar level.
• Verify this is a subsequent encounter, not an initial or sequela visit.
• Pair with an external cause code if the etiology of the dislocation is known and relevant.
