Nanox.AI vs Optellum Virtual Nodule Clinic

A hospital with a low-dose CT lung screening program can spend on either. Nanox's HealthCCSng reads non-gated, non-contrast chest CT in adults 30 to 85 and returns an exact calcium score with a four-category result (K241440, decided August 19, 2024). A Nanox case study published by the vendor reports 31.0% moderate-to-severe calcification among Atlantic Health's lung screening patients.

Optellum's Virtual Nodule Clinic (K202300, decided March 5, 2021) tracks and characterizes incidentally detected pulmonary nodules, and its CNN risk score goes to pulmonologists and radiologists. Pulmonology-led nodule clinics are where it sits, and its reimbursement page lists CPT Category III codes 0721T and +0722T. Nanox's HealthCCSng, HealthOST and HealthFLD target calcium, bone and liver, so a nodule clinic has little to run on them. A screening program that wants coronary calcium from the same scans finds Optellum falling behind, since its clearance covers pulmonary nodules.
