Nondisp fx of 2nd metatarsal bone, unsp ft, 7thK

This code signifies a fracture of the second metatarsal bone in an unspecified foot that has not healed properly and is in a nonunion state. The fracture itself is not displaced, meaning the bone fragments are still in their normal alignment. This diagnosis is used when the patient is receiving follow-up care for this specific complication.

Apply this code when documenting subsequent encounters for a patient whose second metatarsal fracture, regardless of which foot, has failed to unite. This includes situations where the patient is undergoing treatment for the nonunion, such as casting, bracing, or surgical intervention to promote healing. It is appropriate for any visit after the initial treatment for the fracture.

• Ensure documentation clearly states "nonunion" and specifies the second metatarsal.
• Verify the encounter is "subsequent" and not the initial treatment for the fracture.
• Laterality (left or right foot) is unspecified with this code; if known, a more specific code should be sought.
