Dislocation of T4/T5 thoracic vertebra, sequela

This code signifies a long-term complication or residual effect stemming from a prior dislocation of the T4/T5 thoracic vertebrae. It indicates that the initial injury has resolved, but the patient continues to experience issues directly attributable to that past dislocation.

Apply this code when documenting conditions such as chronic pain, instability, nerve impingement, or degenerative changes that are a direct consequence of a previously treated T4/T5 dislocation. This is appropriate for follow-up encounters where the acute phase of the dislocation has passed.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain).
• Ensure documentation clearly links the current condition to the historical T4/T5 dislocation.
• Do not use this code for the initial or acute treatment of a T4/T5 dislocation; use the acute dislocation codes instead.
