Oth traum nondisp spondylolysis of fourth cervcal vert, init

This code signifies a traumatic injury to the fourth cervical vertebra (C4) where a portion of the vertebra has slipped forward or backward relative to the adjacent vertebra, but without complete displacement of the vertebral body. This specific type of spondylolisthesis is caused by trauma, not degenerative changes, and the fracture is closed, meaning the skin is intact.

Use this code for a patient presenting with a newly diagnosed traumatic nondisplaced spondylolisthesis of the C4 vertebra, where the fracture is closed. Documentation should clearly state the traumatic etiology, the specific cervical level (C4), the nondisplaced nature of the spondylolisthesis, and that it is an initial encounter for treatment of the fracture.

• Ensure documentation specifies "nondisplaced" to differentiate from displaced spondylolisthesis.
• Verify the encounter is "initial" for the fracture treatment; subsequent encounters will use different seventh characters.
• Confirm the fracture is "closed" as open fractures have distinct coding.
