Nondisp commnt fx shaft of ulna, unsp arm, 7thC

This code describes a fracture of the ulna bone in the forearm that is broken into multiple pieces (comminuted) but the bone fragments are still in their normal anatomical position (nondisplaced). The fracture is open, meaning the skin and soft tissues are also compromised, and is being treated for the first time.

Use this code for initial encounters with patients presenting with an open, comminuted, and nondisplaced fracture of the ulnar shaft, where the specific arm (left or right) is not documented. This applies to severe open fractures classified as Type IIIA, IIIB, or IIIC according to the Gustilo-Anderson classification.

• Ensure documentation specifies "nondisplaced" and "comminuted" for the ulnar shaft.
• Verify the encounter is "initial" and the open fracture type is IIIA, IIIB, or IIIC.
• If the arm is specified (left or right), a more specific code should be used.
