Nondisp fx of navicular of unsp foot, subs for fx w nonunion

This code signifies a fracture of the navicular bone in the foot that has not healed properly (nonunion) and is not displaced. The specific foot (left or right) is not documented. This indicates the patient is receiving follow-up care for this unhealed fracture.

Apply this code when a patient presents for ongoing treatment, evaluation, or management of a previously diagnosed nondisplaced navicular fracture of the foot that has failed to unite. This includes scenarios where surgical intervention for nonunion is being planned or has already occurred, or when conservative management for the nonunion is continuing.

• Ensure documentation clearly states "nonunion" and "nondisplaced" for the navicular fracture.
• This code is for an unspecified foot; if the laterality is known, a more specific code should be used.
• The "K" seventh character indicates a subsequent encounter for a fracture with nonunion, implying active treatment or monitoring of the nonunion.
