Unsp physl fx upper end l fibula, subs for fx w delay heal

This code indicates an unspecified fracture of the growth plate (physis) at the upper end of the left fibula. It is used when the patient is receiving follow-up care for this fracture, and the healing process is taking longer than expected.

Apply this code for a patient presenting for a subsequent visit related to a left proximal fibular physeal fracture that has not healed within the anticipated timeframe. This would include scenarios where imaging shows persistent fracture lines or clinical signs of non-union/malunion are being monitored. It is appropriate for ongoing management of the delayed healing process, such as cast changes, physical therapy, or surgical planning for revision.

• Ensure documentation clearly specifies "left" fibula and "upper end" or "proximal" to support laterality and location.
• The "G" seventh character signifies a subsequent encounter with delayed healing; do not use for initial treatment or routine healing.
• Always sequence this code after any definitive treatment codes (e.g., for cast application, surgical intervention) if applicable to the encounter.
