No. G0279 is an add-on code and must always be billed with a diagnostic mammography code (typically 77065 for unilateral or 77066 for bilateral). It is not billable as a standalone code. G0204 is an older digital mammography code and has largely been replaced, so make sure you use the correct pairing.
