Subluxation of L1/L2 lumbar vertebra, initial encounter

This code signifies a partial dislocation or misalignment of the first and second lumbar vertebrae (L1 and L2) in the spine. This condition involves the vertebral bodies and their articulating facets, but the joint surfaces remain in partial contact.

Apply this code for a patient presenting with a newly diagnosed or acutely treated subluxation of the L1/L2 segment. This is appropriate for the initial evaluation and management of the injury, such as in an emergency department visit or the first encounter with a chiropractor or physical therapist for this specific issue.

• Ensure documentation clearly specifies "subluxation" and not a complete dislocation.
• Verify the encounter is indeed the "initial encounter" for this specific injury.
• Later encounters for the same injury would require a subsequent encounter (D) or sequela (S) seventh character.
