Unspecified fracture of shaft of unspecified fibula, sequela

This code signifies a long-term complication or late effect stemming from an unspecified fracture of the fibular shaft. It indicates that the initial acute injury has healed, but the patient continues to experience issues directly attributable to the prior fracture. The specific nature of the original fracture and the affected side are not detailed.

Apply this code when documentation clearly indicates a sequela (e.g., malunion, nonunion, chronic pain, deformity, functional limitation) resulting from a past fibular shaft fracture. This is appropriate for follow-up encounters addressing these persistent issues, not for the initial acute fracture treatment. Ensure the medical record explicitly links the current condition to the previous fracture.

• Always assign an additional code to specify the nature of the sequela (e.g., M84.4- for malunion, M84.3- for nonunion).
• This code is for an unspecified fibula; if the laterality (left/right) is known, a more specific code should be used.
• Do not use this code for initial or subsequent encounters for an active, healing fracture.
