Nondisp spiral fx shaft of ulna, unsp arm, 7thB

This code signifies a break in the ulna bone, specifically a spiral fracture occurring along the shaft, which has not shifted out of alignment. The fracture is open, meaning the bone has broken through the skin, and is classified as either Type I or Type II according to the Gustilo-Anderson classification system. This code is used for the initial treatment of such an injury when the affected arm is not specified.

Use this code for the initial encounter when a patient presents with a newly diagnosed, nondisplaced spiral fracture of the ulnar shaft that is open (Type I or II). This applies when the medical record does not specify whether the injury is to the left or right arm. It is appropriate for the initial surgical repair or other definitive treatment of the open fracture.

• Ensure the documentation clearly states "nondisplaced" and "spiral fracture of shaft of ulna."
• Verify the fracture is explicitly documented as "open" and classified as Gustilo-Anderson Type I or II.
• Only use this code for the initial encounter for treatment; subsequent care will require a different seventh character.
