Nondisp commnt fx shaft of humer, unsp arm, init for opn fx

This code signifies a break in the main part (shaft) of the humerus bone that has shattered into multiple pieces but where the bone fragments remain in their normal alignment. This specific code is for an open fracture, meaning the skin and soft tissue were also broken, exposing the bone to the outside environment. It represents the initial treatment for this injury.

Use this code for a patient presenting with a newly diagnosed comminuted fracture of the humeral shaft that is not displaced, and where the fracture is open. This code is appropriate for the initial encounter for treatment of such an injury, regardless of the specific arm affected.

• Ensure documentation clearly specifies "nondisplaced" and "comminuted" for the humeral shaft fracture.
• Verify that the fracture is explicitly documented as "open" to differentiate from closed fractures.
• Confirm this is the patient's initial encounter for this specific fracture to use the "B" seventh character.
