Nondisp bicondylar fx l tibia, subs for clos fx w nonunion

This code describes a fracture involving both condyles of the left tibia that has not shifted from its normal anatomical position. The patient is in a subsequent phase of care, indicating they are receiving ongoing treatment for this fracture. Importantly, the fracture is showing signs of nonunion, meaning it is failing to heal properly.

Use this code for follow-up encounters where a patient is being treated for a bicondylar left tibial fracture that remains nondisplaced. This is specifically for situations where the physician has documented evidence of nonunion, such as persistent pain, instability, or radiographic findings indicating a lack of healing progression. It applies after the initial treatment has begun and the patient is still under active management for the fracture's healing.

• Ensure documentation clearly specifies "bicondylar" and "nondisplaced" for the left tibia.
• Verify that the encounter is subsequent to the initial treatment and that nonunion is explicitly documented.
• Confirm the fracture is closed; open fractures would require a different code.
