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

This code signifies a fracture of the furthest bone in the thumb, which has not shifted out of its normal position. The patient is in the healing phase, and the fracture is progressing as expected without complications.

This code is appropriate for follow-up encounters where a patient is receiving ongoing care for a previously diagnosed nondisplaced distal phalanx thumb fracture. It indicates that the healing process is routine and no adverse events or delayed healing are noted.

• Ensure documentation specifies "unspecified thumb" if laterality is not documented.
• Confirm the encounter is for subsequent care and not the initial treatment.
• Verify that the fracture is explicitly documented as "nondisplaced" and healing is "routine."
