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

This diagnosis code indicates a fracture of the posterior process of the left talus that has not shifted from its normal anatomical position, but is currently healing improperly, resulting in a malunion. This means the bone fragments have united, but in a position that is anatomically incorrect, potentially leading to functional impairment.

Use this code when documenting a patient's follow-up visit for a previously diagnosed nondisplaced posterior talar process fracture of the left foot, and imaging or clinical assessment confirms that the fracture has healed or is healing with malunion. This applies to situations where the patient is receiving ongoing care for the complications arising from the improper healing.

• Ensure documentation clearly specifies "left" talus and "posterior process" for anatomical accuracy.
• Verify that the encounter is for follow-up care related to the malunion, not the initial injury or routine healing.
• Confirm that the fracture was initially nondisplaced, as this code specifically refers to that initial presentation.
