Nondisplaced pilon fracture of unspecified tibia, sequela

This code signifies a pilon fracture of the tibia that has healed or is in a chronic stage, with no displacement of the bone fragments. A pilon fracture involves the weight-bearing surface of the distal tibia, near the ankle joint, and can significantly impact ankle function. The "nondisplaced" aspect indicates that the bone fragments maintained their anatomical alignment.

This code is appropriate for documenting the long-term effects or complications arising from a previously sustained nondisplaced pilon fracture of an unspecified tibia. It should be used when the patient is presenting for follow-up care, management of residual symptoms (e.g., chronic pain, stiffness, arthritis), or assessment of functional limitations directly attributable to the past fracture, after the initial healing phase has concluded.

• Always ensure documentation clearly links the current encounter to the sequelae of the past fracture.
• Do not use this code for initial treatment or active healing phases of a pilon fracture; use acute fracture codes instead.
• Specify laterality (left or right tibia) if known; "unspecified" should only be used when laterality is truly undocumented.
