Harrison.ai vs Optellum Virtual Nodule Clinic
Optellum Virtual Nodule Clinic scores lung cancer risk on CT nodules and tracks them, and its 510(k) K202300 covers the CADx function for pulmonologists and radiologists. Optellum's reimbursement page lists CPT Category III codes 0721T and +0722T and a $650.50 Medicare hospital outpatient rate for 2026 under APC 1508, a national average before deductibles. The vendor names UConn Health, Penn Medicine and Vanderbilt University Medical Center as customers and says it integrates with RapidAI's Rapid Enterprise platform. Harrison.ai fits an NHS trust radiology department reporting chest X-rays, where the vendor says 45+ NHS Trusts use it. It reads chest CT with up to 167 radiological features by the vendor's count, and its openFDA records are triage products plus Annalise Enterprise. A pulmonology-led nodule clinic choosing a cancer-risk score is better served by Optellum, since K202300 names that CADx function.
