Unsp fracture of shaft of left ulna, init for clos fx

This code signifies a fracture affecting the main body (shaft) of the ulna bone in the left forearm, where the specific type of fracture (e.g., transverse, oblique, spiral) is not documented. It indicates that the skin over the fracture site is intact (closed fracture) and this is the first time the patient is receiving treatment for this injury.

This code is appropriate when documentation confirms a left ulnar shaft fracture, but the physician's notes do not specify the fracture type. It is used for the initial treatment of a closed fracture, such as in an emergency department visit or the first orthopedic consultation following the injury.

• Ensure the documentation explicitly states "left ulna" and "shaft" to support this code.
• Verify that the encounter is for the initial treatment of the fracture; subsequent encounters will require a different seventh character.
• Only use this code when the fracture type (e.g., transverse, oblique) is truly unspecified in the medical record. If a type is mentioned, a more specific code should be selected.
