Nondisp fx of neck of unsp talus, subs for fx w malunion

This code describes a follow-up encounter for a patient who previously sustained a fracture to the neck of an unspecified talus bone, and that fracture has healed in an imperfect or misaligned position. The initial fracture was not displaced, meaning the bone fragments remained in their anatomical alignment at the time of injury.

This code is used when a patient presents for ongoing care, evaluation, or treatment related to a previously diagnosed nondisplaced talar neck fracture that has subsequently developed malunion. This could include assessment for pain, functional limitations, or planning for corrective procedures due to the malaligned healing.

• Ensure documentation clearly specifies "malunion" as the complication of the fracture healing.
• Verify that the encounter is subsequent to the initial fracture treatment, not the initial injury encounter.
• Confirm the fracture location is the "neck of the talus" and laterality is unspecified.
