Fx unsp phalanx of right thumb, subs for fx w nonunion

This code signifies a non-healing fracture of an unspecified bone in the right thumb, specifically when the patient is receiving follow-up care for this condition. Nonunion indicates that the bone fragments have failed to unite after a typical healing period, requiring further medical intervention. This diagnosis suggests a persistent issue with bone healing in the right thumb.

Use this code for patients presenting for ongoing treatment of a right thumb phalanx fracture that has not healed properly. This includes scenarios where the patient is undergoing additional surgical procedures, casting, or other interventions aimed at promoting union after initial attempts have failed. It is appropriate for any subsequent encounter related to the nonunion of this specific fracture.

• Ensure documentation clearly specifies "nonunion" and the right thumb phalanx.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Always review the medical record for laterality and the specific phalanx if documented, as more specific codes may exist.
