Subluxation of T4/T5 thoracic vertebra, sequela

This code describes a long-term or residual effect resulting from a previous subluxation (partial dislocation) of the thoracic vertebrae at the T4-T5 level. It indicates that the patient is currently experiencing ongoing symptoms or complications directly attributable to that past injury, rather than an acute or initial episode.

Use this code when documenting a patient presenting with chronic pain, limited range of motion, neurological deficits, or other persistent issues that are a direct consequence of a previously treated or resolved T4/T5 subluxation. This applies to situations where the initial injury has healed, but its lasting impact continues to affect the patient.

• Always ensure documentation clearly links the current condition to a past T4/T5 subluxation.
• Do not use this code for acute or initial subluxations; those require codes from the initial encounter or subsequent encounter categories.
• A seventh character 'S' (sequela) is mandatory for this code, indicating the long-term nature of the condition.
