Subluxation of T4/T5 thoracic vertebra, initial encounter

This code signifies a partial dislocation of the T4 and T5 vertebrae in the thoracic spine. It indicates that the vertebral bodies are misaligned, but the articulating surfaces remain in partial contact. This condition can lead to localized pain, muscle spasm, and restricted range of motion in the mid-back.

Use this code for the initial encounter of a patient presenting with a diagnosed subluxation specifically at the T4/T5 level. This applies when the patient is receiving active treatment for the injury. It is appropriate for acute injuries resulting from trauma, sudden movements, or other precipitating events.

• Ensure documentation clearly specifies "subluxation" and the exact vertebral levels T4/T5.
• The "A" seventh character indicates an initial encounter for active treatment; subsequent encounters will require different seventh characters.
• Do not use this code for complete dislocations (luxations) or for subluxations at other vertebral levels.
