Nondisp pilon fx unsp tibia, 7thN

This code signifies a pilon fracture of the tibia, meaning a break at the very bottom of the shin bone near the ankle joint, which is currently not aligned (nondisplaced). It specifically indicates that the fracture was an open injury (meaning the bone broke through the skin) of a severe type (IIIA, IIIB, or IIIC) and has failed to heal properly, resulting in a nonunion. This is a follow-up encounter for the ongoing management of this complex healing issue.

Use this code for subsequent encounters with a patient who has a previously diagnosed nondisplaced open pilon fracture of an unspecified tibia, where the initial open injury was classified as type IIIA, IIIB, or IIIC, and the fracture has not united. This applies when the patient is receiving continued treatment for the nonunion, such as follow-up appointments, cast changes, or preparation for further surgical intervention.

• Ensure documentation clearly specifies "nondisplaced" and "nonunion" for the pilon fracture.
• Verify the original open fracture type was IIIA, IIIB, or IIIC; this is crucial for accurate coding.
• This code is for subsequent encounters; do not use for the initial treatment of the fracture.
