Oth fracture of shaft of unsp ulna, init for clos fx

This code signifies a fracture affecting the main body (shaft) of the ulna bone, where the specific location on the shaft is not documented. The skin overlying the fracture remains intact, and this encounter represents the initial treatment for the injury.

Apply this code when documentation confirms a closed fracture of the ulnar shaft, but the medical record does not specify if it's a proximal, middle, or distal shaft fracture. This is appropriate for the first visit or admission related to the fracture.

• Ensure the documentation explicitly states "ulna shaft fracture" without further specificity regarding the shaft segment.
• Confirm the fracture is closed; if open, a different code is required.
• Verify this is the initial encounter for treatment; subsequent encounters will use different seventh characters.
