Displaced fracture of trapezium, left wrist, sequela

This code signifies a fracture of the trapezium bone in the left wrist that is no longer in its anatomical alignment. It specifically indicates that this is a sequela, meaning it represents a complication or residual effect of an initial injury, rather than an acute fracture. This could involve malunion, nonunion, or other long-term issues stemming from the original trauma.

This code is appropriate for documenting a patient encounter where a previously sustained, displaced left trapezium fracture is being managed for its long-term effects. This includes follow-up care for complications like chronic pain, limited range of motion, or surgical intervention to correct a malunion or nonunion. It should be used when the acute phase of the injury has passed.

• Ensure the medical record clearly documents the displacement and the sequela nature of the fracture.
• Do not use this code for initial or acute displaced trapezium fractures; those require codes from the initial encounter category.
• Always review the entire encounter documentation to determine if additional codes for associated conditions or complications are warranted.
