Nondisp fx of prox phalanx of unsp fngr, 7thK

This code signifies a finger injury involving a break in the upper bone of an unspecified finger that has not healed properly, despite prior treatment. The fracture fragments are still in their normal anatomical alignment, but the bone has failed to unite.

Apply this code when documenting a patient presenting for ongoing management of a previously treated, but unhealed, nondisplaced proximal phalanx fracture of an unspecified finger. This is used for follow-up encounters where nonunion is the primary concern.

• Ensure documentation clearly states "nonunion" and specifies the proximal phalanx of a finger.
• Verify the fracture is indeed nondisplaced; displaced fractures would require a different code.
• This code indicates a subsequent encounter, so it should not be used for the initial injury.
