Unsp traum nondisp spondylolysis of 3rd cervcal vert, 7thG

This code describes a traumatic injury to the third cervical vertebra (C3) where a nondisplaced spondylolisthesis (forward slippage) occurred due to trauma, but the specific type of spondylolisthesis is not documented. The "G" seventh character indicates that the patient is receiving follow-up care for this fracture, and healing is progressing slower than expected.

Use this code for a patient presenting for ongoing management of a C3 traumatic nondisplaced spondylolisthesis that is not healing at the expected rate. Documentation should clearly state "delayed healing" and specify the third cervical vertebra as the affected site. This code is appropriate when the exact type of spondylolisthesis (e.g., isthmic, degenerative) is not specified in the medical record.

• Ensure documentation explicitly states "delayed healing" for the seventh character "G" to be appropriate.
• Verify the specific cervical vertebra involved; this code is only for C3.
• Do not use if the spondylolisthesis is displaced, if the cause is non-traumatic, or if the healing is routine or malunion.
