Unsp traum nondisp spondylolysis of 4th cervcal vert, 7thD

This code describes a follow-up encounter for a fracture where the fourth cervical vertebra has slipped forward (spondylolisthesis) without displacement, and the cause was traumatic. The fracture is healing routinely, indicating no complications or delayed healing.

Use this code for patients presenting for follow-up care of a previously diagnosed traumatic, nondisplaced spondylolisthesis of C4. Documentation should confirm routine healing and specify the traumatic origin of the spondylolisthesis. This code is appropriate when the patient is beyond the initial active treatment phase.

• Ensure documentation clearly states "nondisplaced" and "traumatic" for the spondylolisthesis.
• The 7th character 'D' indicates a subsequent encounter for a fracture with routine healing; do not use for initial treatment or complicated healing.
• Distinguish from congenital or degenerative spondylolisthesis, which would use different codes.
