Question:

How do you code for a screening mammogram when additional magnification views are required for a suspected abnormality? May I code both a diagnostic mammogram and a screening mammogram?

Answer:

If a screening mammogram is performed and, after film review, pathology is suspected and additional views are taken, it would be appropriate to charge for both a screening mammogram and a diagnostic mammogram.

When the additional diagnostic views are done on the same day as a screening mammogram, Medicare requires that providers append modifier GG to the diagnostic mammography CPT code used to designate that a screening procedure was performed in conjunction with a diagnostic procedure. Modifier 59 should be added to the screening mammogram code.
