Nondisp comminuted fracture of shaft of ulna, unsp arm, init

This code signifies a fracture of the ulna's shaft where the bone is broken into multiple fragments (comminuted) but the bone ends remain in their normal anatomical alignment (nondisplaced). The specific arm affected is not documented, and this code is for the initial treatment of a closed fracture, meaning the skin is intact over the fracture site.

Apply this code for a patient presenting with a newly diagnosed, comminuted, and nondisplaced fracture of the ulnar shaft when the laterality (left or right arm) is not specified in the medical record. This is appropriate for the initial encounter where definitive treatment, such as casting or splinting, is being initiated.

• Ensure documentation explicitly states "nondisplaced" and "comminuted" for the ulnar shaft.
• Only use this code if the arm laterality is truly unspecified; otherwise, select a more specific code.
• The "A" in the seventh character indicates an initial encounter for active treatment of the fracture.
