Dislocation of C7/T1 cervical vertebrae, sequela

This code signifies a long-term complication or late effect resulting from a previous dislocation at the junction of the seventh cervical and first thoracic vertebrae. This could include chronic pain, neurological deficits, or instability that persists after the initial injury has healed.

Apply this code when documenting conditions directly attributable to a past C7/T1 dislocation, such as persistent radiculopathy, myelopathy, or chronic instability. Documentation should clearly link the current condition to the historical dislocation, often requiring a history of the initial injury and ongoing clinical findings.

• Ensure the documentation explicitly states the condition is a "sequela" or "late effect" of a prior dislocation.
• Do not use for acute dislocations; those require codes from the acute injury section.
• Always sequence the sequela code first, followed by codes for the specific manifestations (e.g., chronic pain, neurological deficits).
