Greenstick fx shaft of left ulna, subs for fx w routn heal

This code signifies a greenstick fracture affecting the shaft of the left ulna, indicating an incomplete fracture where the bone bends and breaks only on one side. The "D" seventh character specifies that this is a subsequent encounter for the fracture, and the healing process is progressing routinely without complications.

This code is appropriate for follow-up visits where a patient is being monitored for a previously diagnosed greenstick fracture of the left ulnar shaft. It should be used when the fracture is healing as expected and no complications or delayed healing are noted. This code would be assigned after the initial treatment phase and before the fracture is fully healed.

• Ensure the documentation clearly specifies a greenstick fracture of the left ulna shaft.
• The "D" seventh character is crucial for subsequent encounters with routine healing; do not use for initial treatment or encounters with complications.
• Verify that the encounter is for follow-up care and not for the initial diagnosis or treatment of the fracture.
