Unspecified disp fx of third cervical vertebra, sequela

This code signifies a long-term complication or late effect stemming from an unspecified displaced fracture of the third cervical vertebra. It indicates that the initial injury has healed, but the patient continues to experience residual problems directly attributable to that fracture. This could include chronic pain, neurological deficits, or functional limitations.

Apply this code when documentation clearly states that the patient is being treated for a sequela (late effect) of a previously sustained, unspecified displaced C3 fracture. This typically occurs after the acute phase of injury has passed and the fracture itself is no longer actively being treated. Documentation should specify the nature of the sequela and its direct link to the prior C3 fracture.

• Always sequence the sequela code (S12.200S) first, followed by a code describing the specific nature of the sequela (e.g., chronic pain, myelopathy).
• Ensure documentation explicitly states "sequela," "late effect," or similar terminology linking current symptoms to a past C3 fracture.
• Do not use this code for initial encounters or active treatment of the acute C3 fracture; instead, use the appropriate acute fracture code.
