Fx unsp phalanx of r mid finger, subs for fx w nonunion

This code indicates a fracture of an unspecified bone in the right middle finger, where the fracture has failed to heal properly (nonunion). This specific encounter is for ongoing treatment of this nonunion.

Use this code when a patient presents for follow-up care, surgical intervention, or other treatment related to a previously diagnosed right middle finger phalanx fracture that has not united. This applies when the specific phalanx (proximal, middle, or distal) was not documented at the time of the initial injury.

• Ensure documentation clearly states "nonunion" and specifies the right middle finger.
• Verify this is a subsequent encounter for the fracture, not the initial injury.
• If the specific phalanx is known, a more precise code should be used.
