Nondisplaced oblique fracture of shaft of left ulna, init

This code signifies a break in the main part (shaft) of the left ulna bone, specifically an oblique fracture where the break line is angled. The bone fragments remain in their normal anatomical position without significant displacement. This diagnosis is for the initial treatment phase of a closed fracture, meaning the skin over the fracture is intact.

Use this code for a patient presenting with a newly diagnosed, non-displaced oblique fracture of the left ulnar shaft. This is appropriate for the initial encounter where definitive treatment, such as casting or splinting, is being initiated. It would also be used for the initial evaluation in the emergency department or an urgent care setting.

• Ensure documentation specifies "left" ulna and "oblique" fracture type.
• Confirm the fracture is "nondisplaced" and "closed" for accurate code assignment.
• The "A" seventh character indicates the initial encounter for this specific injury.
