Unsp fx shaft of left ulna, subs for clos fx w routn heal

This code indicates a follow-up visit for an unconfirmed fracture located in the shaft of the left ulna. At this stage, the fracture is closed (skin intact) and is progressing through a normal healing process without complications.

This code is appropriate for subsequent encounters where a patient is receiving routine follow-up care for a left ulnar shaft fracture that was initially unspecified. It applies when the fracture is healing as expected and no surgical intervention or complex management is currently required.

• Ensure documentation specifies "left ulna" and "shaft" for accurate laterality and location.
• The "D" seventh character signifies a subsequent encounter for routine healing of a closed fracture.
• Do not use for initial encounters or for fractures with delayed healing, nonunion, or malunion.
