Nondisp fx of dist phalanx of thmb, subs for fx w delay heal

This code signifies a fracture of the furthest bone in the thumb, which has not shifted out of alignment. The patient is in a later stage of care where the fracture is not healing at the expected rate.

Apply this code when documentation indicates a patient is presenting for follow-up care of a nondisplaced distal phalanx thumb fracture, and the physician notes delayed healing. This would typically be used after the initial treatment phase, such as during subsequent clinic visits for cast changes, physical therapy, or imaging to monitor healing progress.

• Ensure documentation explicitly states "delayed healing" for this specific fracture.
• Verify the encounter is "subsequent" and not the initial treatment.
• Confirm the fracture is of the "distal phalanx" and "nondisplaced."
