Displaced comminuted fx shaft of left fibula, sequela

This code signifies a past injury to the shaft of the left fibula that was characterized by multiple bone fragments and displacement, and the patient is now experiencing a complication or residual effect directly related to that old fracture. These sequelae can include chronic pain, nonunion, malunion, deformity, or restricted range of motion.

Apply this code when documenting a patient encounter for a long-term complication or residual condition stemming from a previously sustained, displaced comminuted fracture of the shaft of the left fibula. This is appropriate when the initial acute fracture has healed, but its lasting impact is being addressed.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., M84.48 for malunion).
• Ensure documentation clearly links the current condition to the old left fibula fracture.
• Do not use for acute fractures; this code is exclusively for sequelae.
