Disp fx of first metatarsal bone, unspecified foot, sequela

This code signifies a long-term complication or late effect resulting from a previously sustained displaced fracture of the first metatarsal bone. The original injury has healed, but the patient is now experiencing residual problems directly attributable to that past fracture. The specific foot (left or right) is not documented.

Apply this code when a patient presents with a current condition, such as chronic pain, deformity, nonunion, malunion, or functional limitation, that is a direct consequence of a healed displaced first metatarsal fracture. This code is appropriate for follow-up encounters addressing these persistent issues, long after the initial fracture treatment.

• Always sequence this sequela code after the code for the specific residual condition being treated (e.g., chronic pain, osteoarthritis).
• Ensure documentation clearly links the current problem to the past displaced first metatarsal fracture.
• The "S" seventh character indicates sequela, meaning the initial injury has healed, and the patient is experiencing a late effect.
