Disp fx of 1st metatarsal bone, unsp ft, 7thK

This code signifies a fracture of the first metatarsal bone that is no longer in its anatomical alignment (displaced) and is located in an unspecified foot. The "subsequent encounter for fracture with nonunion" indicates that the patient is receiving ongoing treatment for a fracture that has failed to heal properly after the expected healing time.

Use this code when documenting follow-up care for a patient with a previously diagnosed displaced first metatarsal fracture where imaging or clinical assessment confirms nonunion. This applies to situations where the provider is managing the nonunion, such as discussing surgical intervention, applying casts, or monitoring the healing process.

• Ensure documentation clearly states "nonunion" and "displaced" for the first metatarsal fracture.
• Verify the encounter type is "subsequent" and not an initial treatment for the fracture.
• Confirm the laterality of the foot is not specified in the medical record to justify "unspecified foot."
