Nondisp fx of prox phalanx of r lit fngr, 7thK

This code describes a fracture of the proximal phalanx of the right little finger that has not displaced, meaning the bone fragments are still in their normal alignment. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and "nonunion" signifies that the fracture has failed to heal completely after the expected healing time.

Use this code for patients presenting for ongoing treatment of a previously diagnosed, nondisplaced fracture of the right little finger's proximal phalanx, where imaging or clinical assessment confirms that the bone has not united. This would apply to scenarios such as continued immobilization, physical therapy, or evaluation for surgical intervention due to the nonunion.

• Ensure documentation clearly specifies "nonunion" and the specific phalanx (proximal) and digit (little finger) are affected.
• Verify laterality (right) is explicitly stated in the medical record.
• Distinguish from malunion (S62.646P) or routine healing (S62.646D, S62.646G, S62.646S).
