Nondisp fx of distal phalanx of thmb, subs for fx w nonunion

This code signifies a fracture of the furthest bone in the thumb, which has not shifted out of its normal alignment. The fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

This code is appropriate for documenting a patient visit where the primary focus is the management of a previously diagnosed, unhealed nondisplaced distal thumb phalanx fracture. This includes encounters for further evaluation, treatment planning, or intervention for the nonunion.

• Ensure documentation clearly states "nondisplaced" and "nonunion" for the distal phalanx of the thumb.
• Verify this is a subsequent encounter for the fracture, not the initial treatment.
• Always review the medical record for laterality if available, as this code specifies "unspecified thumb."
