Unsp traum displ spondylolysis of sixth cervcal vert, 7thB

This code signifies a traumatic forward slippage of the sixth cervical vertebra over the one below it, where the specific type of spondylolisthesis is not documented. It indicates an open fracture, meaning the bone has broken through the skin, and this is the initial treatment encounter for the injury.

Use this code for a patient presenting with a newly diagnosed, open, traumatic spondylolisthesis of the C6 vertebra, where the medical record does not specify the exact type of spondylolisthesis (e.g., degenerative, isthmic). Documentation must clearly state "open fracture" and "initial encounter."

• Ensure documentation explicitly states "unspecified" or lacks further detail regarding the type of spondylolisthesis.
• Verify the encounter is for the initial treatment of the open fracture; subsequent encounters will require different seventh characters.
• Distinguish from non-traumatic spondylolisthesis, which would be coded from the M43 category.
