Oth traum nondisp spondylolysis of 5th cervcal vert, 7thK

This code signifies a follow-up encounter for a patient diagnosed with a traumatic, nondisplaced forward slippage of the C5 vertebra over C6, specifically when the fracture has failed to heal properly (nonunion). This condition is distinct from degenerative spondylolisthesis and implies an injury-related cause.

Apply this code for subsequent visits where a patient is being managed for a previously diagnosed traumatic nondisplaced spondylolisthesis of C5, and documentation explicitly states ongoing treatment for a nonunion of the fracture. This includes scenarios like monitoring, physical therapy, or preparation for revision surgery due to the nonunion.

• Ensure documentation clearly specifies "nondisplaced" and "traumatic" etiology for the C5 spondylolisthesis.
• Verify that the encounter is for a "subsequent encounter" and that "nonunion" of the fracture is explicitly stated.
• Do not use for initial encounters or for malunion; separate codes exist for those scenarios.
