What closing the gap would mean
If screening in these counties rose from 20.3% to 25.3%, five points above today, about 710 to 1,400 more people would be screened each year.
In the National Lung Screening Trial, low-dose CT screening lowered lung cancer deaths by 20% compared with chest X-ray. Today about 59% of lung cancers here are found at a late stage.

Screening at Altru Health System today
Clinicians at Altru Health System locations billed 240 low-dose CT lung screening reads to Medicare fee-for-service in 2024. Including Medicare Advantage and other insurers, we estimate about 380 to 1,000 screenings a year.
Most adults who qualify see a primary care clinician every year. We count 280 primary care clinicians, 5 pulmonologists and 2 thoracic surgeons practicing at Altru Health System locations. A 20 pack-year smoking history is often missing from structured EHR fields, so many eligible patients are never flagged.
CMS Medicare Physician and Other Practitioners 2024 (CPT 71271); clinicians matched to Altru Health System by practice address using the AHRQ Compendium of U.S. Health Systems 2023, so reads billed by outside radiology groups are not included. The all-payer estimate scales Medicare fee-for-service by the local Medicare Advantage share (37%, CMS) and, at the high end, by the share of eligible adults under 65 (64%).

LungNAV Reach
An AI patient navigator that texts and calls patients in 70+ languages, answers questions about the scan, and hands each patient to your scheduling team or nurse navigators with a call summary.
LungAI Second opinion
Gives radiologists a malignancy risk score for each nodule, factoring in change since the prior scan, inside the PACS and CADe software they already use. The radiologist makes the final call.
