Nondisp seg fx shaft of l fibula, 7thN

This code describes a specific type of fibula fracture: a segmental fracture of the shaft that is not displaced. The "subsequent encounter" indicates ongoing treatment for a previously diagnosed fracture. The "open fracture type IIIA, IIIB, or IIIC with nonunion" specifies that the skin was broken at the time of injury, the fracture has not healed as expected, and the severity of the open wound.

Use this code for follow-up encounters when a patient is receiving care for a previously diagnosed, nondisplaced segmental shaft fracture of the left fibula that was initially an open fracture (Type IIIA, IIIB, or IIIC) and has now developed nonunion. This applies when the patient is still under active treatment for the nonunion, such as during clinic visits for cast changes, wound care, or evaluation for surgical intervention.

• Ensure documentation clearly specifies "nondisplaced" and "segmental" for the fibula shaft fracture.
• Verify that the initial injury was an open fracture of the specified types (IIIA, IIIB, or IIIC) and that nonunion is explicitly documented.
• Confirm this is a "subsequent encounter" for ongoing care, not an initial diagnosis or a sequela.
