Oth fracture of unsp talus, subs for fx w nonunion

This code describes a situation where a patient has a fracture of the talus, but the specific location of the fracture within the talus is not documented. Importantly, this code is used when the fracture has not healed properly (nonunion) and the patient is presenting for follow-up care related to this ongoing issue.

Use this code for a patient who has previously sustained an unspecified talus fracture and is now being seen for management of a nonunion. This applies to encounters where the focus is on addressing the failed healing process, such as evaluating for surgical intervention, casting, or other treatments aimed at promoting union.

• Ensure documentation clearly states "nonunion" and that the encounter is for subsequent care of the fracture.
• Verify that the specific site of the talus fracture is not documented; otherwise, a more specific code should be used.
• Do not use for initial treatment of the fracture or for routine follow-up of a healing fracture without nonunion.
