Nondisp dome fracture of unsp talus, subs for fx w malunion

This code describes a fracture of the dome (superior articular surface) of the talus that was initially nondisplaced but has since healed in an imperfect or misaligned position. The "unspecified talus" indicates that the laterality (left or right) of the foot is not documented.

This code is used when a patient presents for follow-up care of a previously diagnosed nondisplaced talar dome fracture, and imaging or clinical assessment confirms that the fracture has healed with a degree of malunion. This could involve ongoing pain, limited range of motion, or other complications directly attributable to the malunion.

• Ensure documentation clearly states "malunion" and specifies the talus as the affected bone.
• Verify that the initial fracture was indeed nondisplaced; otherwise, a different code for a displaced fracture with malunion would be appropriate.
• Confirm that this is a subsequent encounter for the fracture, not the initial treatment or a sequela of a fully healed fracture.
