Subluxation of T12/L1 thoracic vertebra, initial encounter

This code signifies a partial dislocation of the spinal joint between the twelfth thoracic vertebra (T12) and the first lumbar vertebra (L1). It indicates that the vertebral bodies are no longer properly aligned, but the joint surfaces remain in partial contact. This condition can lead to localized pain, muscle spasm, and restricted movement in the thoracolumbar region.

Apply this code for a patient presenting with a newly diagnosed subluxation at the T12/L1 vertebral segment, typically following trauma or sudden movement. It is appropriate when the patient is receiving initial active treatment for the injury. This code would be used for the first encounter related to this specific injury.

• Ensure documentation specifies the T12/L1 segment and confirms it is a subluxation, not a full dislocation.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
• Always review the medical record for laterality if applicable to other spinal codes, though not directly relevant for this specific vertebral segment.
