Nondisp oblique fx shaft of unsp ulna, 7thR

This code signifies a follow-up encounter for a patient with an oblique fracture of the shaft of the ulna, where the bone fragments are still aligned (nondisplaced). The initial injury was an open fracture, specifically one of the more severe types (IIIA, IIIB, or IIIC), and the fracture has healed in a misaligned position (malunion).

This code is appropriate for subsequent encounters when a patient is receiving ongoing treatment or evaluation for a previously sustained open oblique ulnar shaft fracture that has resulted in malunion. This includes scenarios such as planning for corrective surgery, assessing functional limitations due to the malunion, or managing complications related to the malunion.

• Ensure documentation clearly specifies "nondisplaced" and "oblique" for the fracture type.
• Verify the original injury was an "open fracture type IIIA, IIIB, or IIIC" and that "malunion" is present.
• The "R" seventh character indicates a subsequent encounter for a fracture with malunion.
