Fracture of unsp phalanx of left thumb, init for clos fx

This diagnosis code signifies a broken bone in an unspecified phalanx of the left thumb. It indicates that the fracture is closed, meaning the skin remains intact over the injury site, and it is the initial treatment encounter for this specific injury.

This code is appropriate for documenting the first visit for a patient presenting with a newly diagnosed, non-displaced or minimally displaced fracture of any phalanx (proximal or distal) of the left thumb, where the skin is not broken. It would be used following an X-ray confirmation of the fracture.

• Ensure documentation specifies "left thumb" and "closed fracture" for accurate code assignment.
• Verify this is the patient's initial encounter for this specific injury; subsequent encounters will require a different seventh character.
• If the specific phalanx (proximal or distal) is known, a more specific code should be used.
