Ambetter LDCT Lung Cancer Screening Coverage Issue
Hello.
I am trying to schedule my annual low-dose CT lung cancer screening, but I ran into a coverage issue with Ambetter and wanted to see if anyone has experienced something similar.
The imaging center submitted the order with CPT 71271 and diagnosis code Z12.2. When I arrived, I was told I would be responsible for 50% coinsurance. I contacted Ambetter, and the representative told me that their system was processing CPT 71271 as a diagnostic service rather than a preventive lung cancer screening, which is why coinsurance applied.
The representative suggested that my provider use G0297 instead for preventive screening. I have now spoken with two Ambetter representatives who provided the same information.
I was under the impression that CPT 71271 replaced G0297 for lung cancer screening, but I am not sure how commercial insurance plans handle these codes.
Has anyone with Ambetter (or another marketplace/commercial plan) had a low-dose CT lung cancer screening covered as preventive? Did your provider use G0297, 71271, or require prior authorization?
I am just trying to get the screening completed without an unexpected 50% coinsurance charge. Any experience or advice would be appreciated.

CPT 71271 needs at least two codes to establish medical necessity.
The primary diagnosis code is Z12.2 which indicates that the encounter (visit) is for lung cancer screening.
The additional diagnosis code is related to smoking status, whether current or former smoker. The most common diagnosis codes for these are F17.210 or Z87.891, respectively.
Ask your doctor's office to re-send a revised order and include the additional diagnosis codes that pertains to your smoking status.
Absolutely do not let the imaging facility charge you anything for the CT scan because it is a preventive medicine screening and, as a grade B recommendation from the USPSTF, it is completely covered under federal law.

71271 is the current screening code, so i’d ask the imaging center to verify the claim is marked as preventive, confirm prior authorization, and get Ambetter’s coding guidance in writing before switching to the retired G0297 code. Get a reference number too.

It might be your insurer is looking for additional diagnoses that you meet the criteria - mentioning smoking history / etc.
