Unsp traum nondisp spondylolysis of third cervcal vert, init

This code signifies a traumatic injury to the third cervical vertebra (C3) where the vertebra has slipped forward (spondylolisthesis) but remains in its normal anatomical position (nondisplaced). The specific type of fracture causing the spondylolisthesis is not documented, and the skin over the injury is intact (closed fracture).

Apply this code for initial encounters when a patient presents with a newly diagnosed traumatic nondisplaced spondylolisthesis of C3, and the specific fracture type is not yet identified or documented. Documentation should clearly state "traumatic spondylolisthesis," "C3," "nondisplaced," "closed fracture," and indicate the initial treatment phase.

• Ensure documentation specifies "nondisplaced" to differentiate from displaced spondylolisthesis.
• Verify the encounter is "initial" for active treatment; subsequent encounters will use a different 7th character.
• Do not use this code if the specific type of fracture (e.g., burst, compression) is known and documented.
