Nondisp pilon fx l tibia, 7thM

This code describes a fracture of the distal end of the left tibia, specifically involving the weight-bearing surface of the ankle joint (pilon), which is not displaced. The fracture is an open type I or II, indicating a break in the skin with minimal to moderate soft tissue damage, and has failed to heal properly, resulting in a nonunion.

This code is used for follow-up encounters when a patient is receiving ongoing treatment for a previously diagnosed nondisplaced pilon fracture of the left tibia that was initially an open type I or II fracture and has now been complicated by nonunion. This would include situations such as continued cast care, wound management, or preparation for surgical intervention to address the nonunion.

• Ensure documentation clearly specifies "nondisplaced" and "left tibia" for the pilon fracture.
• Verify the original open fracture type (I or II) and the current status of "nonunion" are explicitly documented.
• This code is for subsequent encounters; an initial encounter for this specific condition would use a different code.
