Unsp fracture of left talus, subs for fx w nonunion

This code signifies an unspecified fracture of the left talus that has failed to heal properly after an initial treatment. The patient is currently undergoing active management for this nonunion, which could involve further surgical intervention or conservative measures.

Apply this code when documentation indicates a patient is being treated for a left talus fracture that has not united, and the specific type of talus fracture (e.g., body, neck) is not specified. This is appropriate for follow-up visits where the nonunion is the primary focus of care.

• Ensure the documentation clearly states "nonunion" and specifies the left talus.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Do not use if the specific anatomical site of the talus fracture is documented (e.g., S92.122K for fracture of lateral process of left talus).
