Disp fx of 3rd metatarsal bone, unsp ft, 7thK

This code signifies a fracture of the third metatarsal bone in an unspecified foot that has not healed properly after initial treatment. The fracture fragments are no longer in their correct anatomical alignment, and the bone has failed to unite. This diagnosis indicates ongoing management for a complicated healing process.

Use this code for patients presenting for follow-up care of a previously diagnosed and treated displaced third metatarsal fracture where imaging or clinical assessment confirms nonunion. This applies to situations such as cast changes, physical therapy, or surgical planning for corrective procedures due to the nonunion.

• Ensure documentation clearly states "nonunion" and "displaced" for the third metatarsal.
• Confirm the encounter is "subsequent" to the initial fracture treatment.
• If the foot (left or right) is specified, a more specific code should be used.
