Path fx in neopltc disease, unsp tibia and fibula, sequela

This code signifies a fracture of the tibia and/or fibula that occurred due to underlying neoplastic disease, where the specific bone affected is not documented. The "S" at the end indicates that this encounter is for the sequela (late effects) of the fracture, meaning the patient is presenting for treatment of a complication or residual condition related to the healed or healing pathological fracture.

Apply this code when a patient is being treated for a long-term complication or residual effect of a pathological fracture of the unspecified tibia and fibula, which was caused by cancer. Documentation should clearly state the fracture was pathological due to neoplasm and that the current encounter addresses a sequela, such as malunion, nonunion, or chronic pain after the initial fracture treatment.

• Always sequence this sequela code after the code for the underlying neoplastic disease.
• Ensure documentation specifies "pathological fracture" and links it to a neoplastic condition, even if the specific bone of the lower leg is not detailed.
• Do not use this code for initial treatment of the fracture or for subsequent routine follow-up care without a documented sequela.
