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

This code signifies a fracture of an unspecified phalanx (bone) in the right ring finger that has failed to heal properly after the initial treatment. The patient is currently undergoing active management for this nonunion, which may involve further surgical intervention or conservative measures.

This code is appropriate for encounters where a patient is being treated for a previously diagnosed right ring finger phalanx fracture that has not united. This includes follow-up visits for ongoing management of the nonunion, such as casting changes, physical therapy, or preparation for revision surgery. It should be used after the initial healing period has passed and nonunion has been confirmed.

• Always confirm laterality (right) and the specific finger (ring) from the clinical documentation.
• Ensure documentation clearly states "nonunion" and that this is a subsequent encounter for the fracture.
• Do not use for initial fracture treatment or for malunion, which is a different complication.
