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

This code signifies a fracture of an unspecified lesser toe that was initially nondisplaced and is now in a subsequent phase of healing, specifically complicated by nonunion. Nonunion indicates that the bone is failing to heal properly after the initial fracture event. The specific lesser toe involved is not identified.

Apply this code when a patient presents for follow-up care of a previously diagnosed, nondisplaced lesser toe fracture that has not healed within the expected timeframe, and the physician documents nonunion. This is appropriate for ongoing management of the nonunion, including potential surgical intervention or conservative treatment.

• Ensure physician documentation clearly states "nonunion" for a previously nondisplaced lesser toe fracture.
• Verify the encounter is for subsequent care, not the initial treatment of the fracture.
• Do not use if the fracture was displaced or if a specific lesser toe (e.g., second, third) is identified; a more specific code would be required.
