Nondisp pilon fx unsp tibia, subs for clos fx w routn heal

This code signifies a nondisplaced fracture of the pilon, which is the weight-bearing articular surface of the distal tibia. The fracture is currently undergoing routine healing, and the patient is in a subsequent phase of care following initial treatment.

Apply this code for follow-up encounters where a patient with a previously diagnosed nondisplaced pilon fracture of an unspecified tibia is demonstrating expected healing without complications. This is appropriate when the fracture has been closed and is not requiring active intervention beyond routine follow-up.

• Ensure documentation specifies "nondisplaced" and "pilon fracture" of the tibia.
• Confirm the encounter is for "subsequent care" and the fracture is "closed with routine healing."
• Do not use if the fracture is open, displaced, or experiencing delayed/nonunion healing.
