Nondisp unsp fx unsp great toe, subs for fx w nonunion

This code signifies a follow-up encounter for a fracture of the great toe that was initially nondisplaced and whose specific location within the great toe was not documented. The key aspect for this code is the presence of a nonunion, meaning the fracture has failed to heal properly after a typical healing period.

This code is appropriate when a patient presents for ongoing management of a previously diagnosed, nondisplaced, and unspecified great toe fracture that has been determined to be a nonunion. This would typically involve evaluation for further intervention, such as surgical repair or bone stimulation, due to the lack of healing.

• Ensure documentation clearly states "nonunion" for the great toe fracture.
• Verify the fracture was initially nondisplaced and the specific great toe bone (e.g., phalanx) was not specified.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
