Fx unsp tarsal bone(s) of unsp ft, subs for fx w delay heal

This code signifies a fracture of an unspecified tarsal bone in an unspecified foot that is currently undergoing treatment, but the healing process is taking longer than expected. It indicates that the patient is in a subsequent phase of care for the fracture, and the delayed healing is a significant clinical concern.

Use this code when documentation clearly indicates a tarsal bone fracture with delayed healing, and the specific tarsal bone or foot is not identified. This is appropriate for follow-up encounters where the physician is monitoring the fracture's progress and addressing the delayed union.

• Ensure the documentation explicitly states "delayed healing" or similar terminology for the fracture.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
• If the specific tarsal bone (e.g., navicular, cuboid) or foot (left/right) is known, a more specific code should be used.
