Dislocation of C3/C4 cervical vertebrae, sequela

This code signifies a long-term complication or residual effect stemming from a prior dislocation of the C3/C4 cervical vertebrae. It indicates that the patient is currently experiencing issues directly attributable to that past injury, rather than an acute dislocation.

Apply this code when documentation clearly states a patient's current symptoms or condition are a sequela of a previously treated C3/C4 dislocation. This is appropriate for chronic pain, neurological deficits, or instability directly linked to the old injury. Supporting documentation should specify the causal relationship to the prior dislocation.

• Ensure the documentation explicitly states "sequela" or describes a chronic condition resulting from a past C3/C4 dislocation.
• Do not use this code for an acute or current dislocation; refer to the acute dislocation codes for those scenarios.
• Always sequence this sequela code first, followed by any additional codes for specific manifestations of the sequela (e.g., chronic pain, neurological deficits).
