In Vivo Analysis of Gastro-Intestinal and Urothelial Lesions (CPB 0783, reviewed 2026-10-27)
Aetna's Clinical Policy Bulletin 0783 (reviewed 2026-10-27) confirms that in vivo analysis technologies for gastrointestinal and urothelial lesions, including confocal laser endomicroscopy, narrow-band imaging, chromoendoscopy and optical biopsy systems, are considered experimental, investigational or unproven for the listed indications. Claims for these services with the listed CPT codes (such as 43206, 43252 and +0397T) and ICD-10 diagnoses will be denied under this policy, so billing staff should review how these services are coded and documented before submission.
