Fx unsp phalanx of r idx fngr, subs for fx w nonunion

This code signifies a fracture of an unspecified phalanx in the right index finger that has failed to heal properly, indicating a nonunion. It is used when a patient is receiving follow-up care for this specific complication after the initial treatment phase.

Apply this code when a patient presents for ongoing management of a right index finger phalanx fracture that has been diagnosed with nonunion. This includes scenarios such as follow-up appointments for monitoring, cast changes, or preparation for surgical intervention to address the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the right index finger phalanx.
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Do not use this code if the fracture is healing normally or if it's a malunion (incorrect alignment).
