Videostroboscopy (CPB 0305, reviewed 2026-04-17)
Aetna considers videostroboscopy medically necessary as a diagnostic procedure for detecting vocal cord pathology, such as polyps, invasive carcinoma, and vocal cord paresis or paralysis, in members who have received both a mirror-image and an endoscopic examination, where no abnormal function or clinical pathology was found with those tests despite persistent symptoms. Aetna considers videostroboscopy experimental, investigational, or unproven for all other indications because its effectiveness for those indications has not been established. Aetna also considers artificial intelligence-based assessment of videostroboscopy experimental, investigational, or unproven for the diagnosis of vocal fold sulcus (sulcus vocalis).
