Fx unsp phalanx of left thumb, subs for fx w routn heal

This code signifies a documented fracture of any phalanx (proximal or distal) of the left thumb, where the patient is presenting for follow-up care during the healing phase. The "D" indicates that the fracture is undergoing routine healing without complications.

Apply this code when a patient with a previously diagnosed left thumb phalanx fracture returns for a scheduled follow-up appointment, such as cast removal, repeat imaging to assess callus formation, or physical therapy initiation, and the healing process is progressing as expected. It is used after the initial encounter for the fracture.

• Ensure documentation specifies "left thumb" and "phalanx" (proximal or distal, if known, though unspecified is acceptable for this code).
• Verify that the encounter is for follow-up care and not the initial treatment or a complication.
• Confirm that the physician's notes indicate routine healing; if complications are present, a different subsequent encounter code (e.g., "G" or "K") would be more appropriate.
