Subluxation of T6/T7 thoracic vertebra, subsequent encounter

This code signifies a partial dislocation or misalignment of the sixth and seventh thoracic vertebrae that occurred previously and is now being addressed again. It indicates that the vertebral bodies are no longer properly articulated, but the joint surfaces remain in partial contact. This condition can lead to localized pain, muscle spasm, and restricted range of motion in the mid-back.

This code is appropriate for follow-up encounters where a patient is receiving ongoing treatment or evaluation for a previously diagnosed subluxation of the T6/T7 thoracic segment. This includes visits for physical therapy, chiropractic adjustments, medication management, or re-assessment of the injury after the initial treatment phase.

• Ensure documentation clearly indicates this is a "subsequent encounter" for the subluxation, not an initial injury.
• Verify the specific vertebral levels (T6/T7) are documented to support the precise code selection.
• Do not use this code for initial injury encounters; a different seventh character would be required.
