65 of the 144 counties had no Medicare lung screening reads billed from a local address in 2024. County names link to their Missing Millions page.

What closing the gap would mean

If screening in these counties rose from 16.2% to the national rate of 18.2%, about 41,400 to 81,500 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 63% of lung cancers here are found at a late stage.

Illustrative estimate: eligible adults (range) times the change in screening rate. Not a forecast or a guarantee.

Screening at Community Health Systems today

Clinicians at Community Health Systems locations billed 2,386 low-dose CT lung screening reads to Medicare fee-for-service in 2024. Including Medicare Advantage and other insurers, we estimate about 5,400 to 15,000 screenings a year.

Most adults who qualify see a primary care clinician every year. We count 3,769 primary care clinicians, 96 pulmonologists and 30 thoracic surgeons practicing at Community Health Systems 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 Community Health Systems 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 (56%, CMS) and, at the high end, by the share of eligible adults under 65 (64%).

Find them, reach them, give radiologists a second opinion

LungIQ Find

Reads clinical notes, diagnoses and medications in the EHR and returns a ranked list of patients likely eligible, including those whose pack-year history is missing. Start with a CSV export refreshed every 1, 3 or 6 months, or connect through FHIR or HL7.

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.

LungAI is an investigational medical device and has not been cleared by FDA. It is not commercially available in the United States.

How we estimate the gap

Modeled estimates from public data. They are not a count of Community Health Systems patients and contain no patient information.

  • Service area: CMS Hospital Service Area File 2025 (counties within 120 miles of a system hospital holding 80% of its Medicare inpatients, plus any county with at least 1%); hospitals from the AHRQ Compendium of U.S. Health Systems, 2023.
  • Eligible adults, low estimate: Oatmeal Health Missing Millions (Census 2025 population, CDC PLACES smoking, USPSTF 2021).
  • Eligible adults, high estimate: University of Minnesota National Lung Cancer Screening Estimates (Haynes 2026), which also counts former smokers.
  • Screening rate: American Lung Association, State of Lung Cancer 2025.
  • Lung cancer cases and deaths: NCI and CDC State Cancer Profiles (incidence 2019 to 2023, deaths 2020 to 2024).
  • Screening volume: CMS Medicare Physician and Other Practitioners, 2024; CMS Medicare Advantage State/County Penetration, September 2026.
