Subluxation of L3/L4 lumbar vertebra, subsequent encounter

This code indicates a partial dislocation or misalignment of the third and fourth lumbar vertebrae (L3/L4) in the spine. It signifies that the patient is receiving follow-up care for this condition after the initial treatment phase.

This code is appropriate for encounters where a patient is being seen for ongoing management, rehabilitation, or evaluation of a previously diagnosed L3/L4 subluxation. This includes visits for physical therapy, chiropractic adjustments, or follow-up imaging to monitor the subluxation's progress.

• Ensure the encounter is not for the initial treatment of the subluxation; use the appropriate initial encounter code for the first visit.
• Verify documentation clearly specifies the L3/L4 level of the lumbar spine.
• Always sequence this code after any primary condition or injury that led to the subluxation, if applicable.
