Nondisp fx of post pro of unsp talus, subs for fx w malunion

This code signifies a fracture of the posterior process of the talus, which is a small bony projection at the back of the ankle bone, that has not shifted from its normal position. The "malunion" aspect indicates that the fracture has healed, but in an unsatisfactory or deformed alignment. This specific code is used for follow-up care after the initial treatment of the fracture.

This code is appropriate for encounters where a patient is being seen for ongoing management or complications related to a previously treated, nondisplaced posterior talar process fracture that has healed incorrectly. This could include evaluations for pain, limited range of motion, or other functional impairments resulting from the malunion. It would also be used for planning or performing corrective procedures for the malunion.

• Ensure documentation clearly states "malunion" and specifies the posterior process of the talus.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Confirm the fracture was initially nondisplaced; if displaced, a different code would be necessary.
