Nondisp fx of navicular of r foot, subs for fx w delay heal

This code signifies a fracture of the navicular bone in the right foot that has not shifted from its normal anatomical position. The patient is in a later stage of care where the fracture is not healing at the expected rate.

Apply this code when a patient presents for follow-up care of a previously diagnosed nondisplaced right foot navicular fracture, and documentation indicates delayed union or healing. This would typically be used after initial treatment and during ongoing management of the fracture.

• Ensure documentation explicitly states "nondisplaced" and "delayed healing" for the right foot navicular.
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Do not use if the fracture is displaced, or if healing is progressing normally.
