Nondisp unsp fx unsp lesser toe(s), subs for fx w malunion

This code describes a situation where a patient has a fracture of an unspecified lesser toe that was initially nondisplaced, but during the healing process, the bone segments have joined in an abnormal position (malunion). This specific code is used when the patient is seen for follow-up care related to this malunion.

Use this code for follow-up encounters where a previously diagnosed nondisplaced unspecified lesser toe fracture is now complicated by malunion. This would apply when the physician is assessing the malunion, planning further treatment, or monitoring its progress. It is not for the initial treatment of the fracture or for a new injury.

• Ensure documentation clearly states "malunion" and that the fracture was initially nondisplaced.
• Verify that the encounter is for follow-up care related to the malunion, not the initial fracture treatment.
• This code specifies "unspecified lesser toe(s)," so avoid using it if a specific lesser toe (e.g., second, third) is documented.
