Subluxation of T8/T9 thoracic vertebra, initial encounter

This code signifies a partial dislocation of the eighth and ninth thoracic vertebrae, where the joint surfaces are no longer in proper alignment but remain in contact. This injury often results in localized pain, muscle spasm, and restricted range of motion in the mid-back region.

This code is appropriate for the initial encounter of a patient presenting with a diagnosed subluxation between the T8 and T9 vertebrae. This could be due to trauma, sudden movements, or degenerative changes. It should be used when the patient is receiving active treatment for the injury.

• Ensure documentation specifies the T8/T9 level and confirms subluxation, not a full dislocation.
• Verify that this is indeed the initial encounter for this specific injury; subsequent encounters will require a different seventh character.
• Look for associated symptoms like pain, neurological deficits, or muscle spasm to support the diagnosis.
