Nondisp pilon fx left tibia, subs for clos fx w delay heal

This code signifies a fracture of the distal end of the left tibia, specifically affecting the weight-bearing surface of the ankle joint (pilon fracture), which has not shifted out of alignment. The patient is in a later stage of healing, and the fracture is not progressing as expected, indicating delayed union.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed nondisplaced pilon fracture of the left tibia is being treated for delayed healing. This includes situations where imaging shows persistent fracture lines or clinical signs indicate a prolonged recovery period for the closed fracture.

• Ensure documentation clearly specifies "nondisplaced" and "left tibia" for accurate laterality and displacement.
• Confirm the encounter is for "subsequent care" and that "delayed healing" is explicitly documented by the provider.
• Do not use for initial encounters or for fractures that are healing normally.
