Disp fx of third metatarsal bone, unspecified foot, sequela

This code signifies a past fracture of the third metatarsal bone in an unspecified foot that was displaced at the time of injury, and the patient is now experiencing a long-term complication or residual effect directly related to that previous fracture. This could include chronic pain, nonunion, malunion, or functional impairment.

Apply this code when documenting a patient presenting with a current condition or symptom that is a direct consequence of a previously sustained, displaced third metatarsal fracture. This is appropriate for follow-up encounters addressing chronic issues stemming from the original injury, rather than the acute fracture itself.

• Requires an additional code to specify the nature of the sequela (e.g., M21.00 for nonunion, M96.0 for pseudarthrosis).
• Do not use for initial or subsequent encounters for the active treatment of the fracture.
• Ensure documentation clearly links the current condition to the prior displaced third metatarsal fracture.
