Subluxation of T3/T4 thoracic vertebra, initial encounter

This code signifies a partial dislocation or misalignment of the third and fourth thoracic vertebrae, specifically when the patient is first presenting for this injury. This subluxation can cause pain, restricted movement, and neurological symptoms depending on the degree of displacement and any associated nerve impingement.

Apply this code for new injuries or acute exacerbations of a pre-existing condition where the patient is receiving initial active treatment for a subluxation between the T3 and T4 vertebrae. This includes emergency room visits, initial consultations with a chiropractor or physical therapist, or the first visit to a physician for this specific injury.

• Ensure documentation clearly specifies the T3/T4 level of subluxation.
• Verify that the encounter is indeed the "initial encounter" for treatment of this specific injury.
• Do not use this code for chronic or follow-up care; instead, select the appropriate subsequent or sequela encounter code.
