Nondisp fx of distal phalanx of left thumb, init for clos fx

This code signifies a break in the furthest bone of the left thumb, which has not shifted out of its normal alignment. The skin over the fracture remains intact, indicating a closed injury. This diagnosis is recorded during the patient's initial visit for this specific injury.

Apply this code when documenting a patient's first presentation for a non-displaced fracture of the distal phalanx of the left thumb. This is appropriate for injuries where the skin is not broken and the bone fragments are still in their anatomical position. It would be used, for example, after a crush injury or direct trauma to the thumb tip.

• Ensure the documentation specifies "left thumb" and "distal phalanx."
• Confirm the fracture is explicitly stated as "nondisplaced" and "closed."
• The "A" in the seventh character indicates an initial encounter for this specific fracture.
