Subluxation of L2/L3 lumbar vertebra, initial encounter

This code signifies a partial dislocation of the L2 and L3 vertebrae in the lumbar spine, where the joint surfaces are no longer perfectly aligned but still maintain some contact. This condition often results in localized pain, muscle spasms, and restricted movement in the lower back.

Apply this code when documentation clearly indicates a subluxation specifically affecting the L2/L3 vertebral segment. This is appropriate for the initial evaluation and treatment of a newly diagnosed or acutely presenting subluxation at this level.

• Ensure the documentation specifies "subluxation" and not a complete dislocation.
• Verify the exact vertebral level (L2/L3) is documented; do not use for other lumbar levels.
• The "A" seventh character indicates an initial encounter for this condition.
