CPT Code 77067: Screening Mammography, Bilateral, with CAD

What is screening mammography with CAD (CPT 77067)?

CPT code 77067 describes screening mammography, bilateral (2-view study of each breast), including computer-aided detection (CAD) when performed. This code represents a preventive imaging service designed to detect breast cancer in asymptomatic patients. The bilateral screening mammography procedure captures standard two-dimensional X-ray images of both breasts, with computer-aided detection (CAD) technology incorporated to assist in image interpretation.

Screening mammograms are fundamentally different from diagnostic mammograms. While diagnostic mammography (represented by different CPT codes) evaluates patients with symptoms or abnormal findings, a bilateral mammogram for screening aims to identify signs of breast cancer in patients without symptoms. Code 77067 specifically applies to bilateral screening examinations in which both breasts are imaged.

A significant feature of CPT code 77067 is the inclusion of computer-aided detection when performed. CAD technology serves as a second set of "eyes" during mammogram interpretation. The computer system assists radiologists by highlighting suspicious areas on mammogram images, potentially improving early breast cancer detection rates.

CPT code 77067 documentation requirements

Proper documentation is essential for healthcare providers to ensure accurate billing and appropriate reimbursement for screening mammography services. The patient's medical record must contain specific elements to support using CPT code 77067.

Documentation for screening mammography must include comprehensive information about the procedure performed, findings, and recommendations. The following elements should be documented in the patient's medical record:

• Patient demographic information and relevant history must be recorded, including age, gender, and risk factors for breast cancer. The service date and indication for screening (rather than diagnostic) mammography should be clearly stated.
• Technical parameters of the examination should document that standard two-view images of each breast were obtained, typically including craniocaudal and mediolateral oblique views. If computer-aided detection was utilized, this should be specifically documented, as it is a component of the mammography service represented by code 77067.
• The report should include comprehensive findings describing breast composition, abnormalities identified, and a final assessment. Clear recommendations for follow-up, including the timing of the next screening examination or the need for additional imaging, are essential components of complete documentation.
• Documentation should also include any examination limitations affecting interpretation, such as breast implants, post-surgical changes, or technical factors. When available, the presence or absence of prior breast surgeries, hormone therapy, or family history that might influence interpretation should be noted.

CPT code 77067 billing guidelines

Understanding the billing guidelines for CPT code 77067 is crucial for ensuring accurate billing, improving revenue cycle management, and maximizing appropriate reimbursement for services rendered.

CPT code 77067 Medicare reimbursement follows specific guidelines established by the Centers for Medicare & Medicaid Services (CMS). Under the Medicare Physician Fee Schedule (MPFS), reimbursement rates for screening mammography are updated annually. Healthcare providers should consult their respective Medicare Administrative Contractor (MAC) for detailed information about local coverage determinations and payment rates.

Several modifiers may be applicable when reporting mammography CPT codes:

• Modifier 26 (Professional component): This modifier indicates that only the professional interpretation of the mammogram was provided, without the technical component. It is used when the physician interprets the mammogram but does not own the equipment or employ the technologists.
• Modifier TC (Technical component): This modifier represents the technical aspects of mammography, including equipment, supplies, and technical staff, without professional interpretation. It is typically used by facilities that provide mammography equipment and technologists but not for professional interpretation.
• Modifier GG: Used to indicate that the screening mammography service was performed for a patient who is asymptomatic and at high risk for developing breast cancer.
• Modifier GH: Indicates a diagnostic mammogram converted from a screening mammogram on the same day. This is used when abnormalities that require immediate diagnostic evaluation are detected during screening.
• Modifier 76 or 77 (Repeat procedure): Applied when a mammography procedure is repeated by the same physician (76) or a different physician (77) on the same day for medical reasons.
