Sometimes, a patient presents only for a breast exam, perhaps prior to a mammogram. Is that a separately billable service?
Newly found lump: A patient who presents with a newly discovered lump and presents to the office can be billed with new or established patient visit codes (depending on the patient status, 99201--99215). Select a code based on the level of service. (History, exam, MDM or time, as appropriate.)
Part of a preventive medicine visit: The breast exam is part of an age/gender appropriate exam.
As part of a pelvic and clinical breast exam on a Medicare patient: Bill code G0101 for Medicare patients (frequency and diagnosis limists apply, see article in Codapedia on this topic.) G0101 must include the clinical breast exam and a total of 7 of the 11 exam elements.
Breast exam only: There is no code for performing only a breast exam.
