Summary
This policy update clarifies that both traditional chromoendoscopy and virtual chromoendoscopy remain investigational (not covered) when used as adjuncts to colonoscopy. The recent update only changed terminology from 'patients' to 'individuals' with no impact on coverage or billing requirements.
Action Required
No immediate action required. Continue to treat chromoendoscopy procedures as investigational/non-covered services. If billing these procedures, use CPT 44799 or HCPCS G6021 as unlisted codes and inform patients these services are considered investigational and may not be covered.
