Breast Ultrasound

What ICD-9 codes could I use for a patient that has recently had breast implants and is having bilateral breast ultrasounds (for screening purposes) instead of a screening mammogram? The patient also had a finding on a previous mammo of an enlarged intramammary lymph node, should this be noted as well?

Screening

look at V76.1x category. Yes, code the previous finding. Get an ABN because the payer may not recognize an ultrasound procedure.
