Nondisp Maisonneuve's fx unsp leg, 7thJ

This code describes a specific type of ankle fracture, a Maisonneuve's fracture, which involves a spiral fracture of the proximal fibula with an associated ankle injury. In this instance, the fracture is nondisplaced, meaning the bone fragments are still in their normal alignment, and it is an open fracture of a severe type (IIIA, IIIB, or IIIC) that is experiencing delayed healing. The specific leg affected is not documented.

Use this code for follow-up encounters where a patient with a previously diagnosed nondisplaced Maisonneuve's fracture of an unspecified leg is being treated for complications related to an open fracture (types IIIA, IIIB, or IIIC) that is not healing as expected. This code is appropriate when the patient is still under active treatment for the delayed union of the fracture.

• Ensure documentation clearly specifies "nondisplaced" and "Maisonneuve's fracture" with an open fracture type IIIA, IIIB, or IIIC.
• The "J" seventh character indicates a subsequent encounter for delayed healing; confirm this is the current phase of care.
• If the specific leg (right or left) is known, a more specific code should be used.
