The screening and diagnostic mammo LCD from FCSO instructs under the Coverage Guidance section that "...detection of a radiographic abnormality may prompt the interpreting radiologist to order additional views on the same day. When this is the case, the mammography is no longer considered to be a screening exam and should be reported as diagnostic."
But then in the section under ICD-10 Codes that support Medical Necessity,
"..when a screening mammo and a diag mammo are performed on the same date of service, for the same patient, append modifier-GG to the diag mammo code. Both the screening mammo and the diag mammo codes should be reported on the same claim."
Can anyone provide insight into that? It sounds contradicting.
