Nondisp commnt fx shaft of unsp fibula, 7thK

This code signifies a comminuted fracture of the fibula's shaft that has not shifted out of alignment, and the patient is in a later stage of care where the fracture has failed to heal properly. "Comminuted" indicates the bone is broken into multiple fragments, while "nondisplaced" means the bone pieces retain their normal anatomical position. "Nonunion" specifically points to a complication where the fracture site shows no signs of healing after an expected period.

This code is appropriate for follow-up encounters when a patient with a previously diagnosed, nondisplaced comminuted fibular shaft fracture is experiencing nonunion, and the fracture is currently being managed non-surgically (e.g., cast changes, physical therapy, monitoring). It would be used when the provider is assessing the ongoing failure of the bone to mend, prior to or in between surgical interventions for the nonunion.

• Ensure documentation clearly states "nondisplaced," "comminuted," and "nonunion" for the fibular shaft.
• Verify this is a subsequent encounter for a closed fracture; open fractures have different coding pathways.
• Confirm the laterality (left/right) is truly unspecified in the medical record before using an "unspecified" code.
