Diagnostic mammography, as represented by CPT® Code 77066, is a specialized radiographic imaging procedure focused on the breast, utilizing low-dose ionizing radiation to produce detailed images. This procedure is specifically designed to evaluate and diagnose breast abnormalities, particularly in patients who exhibit symptoms of breast disease or have palpable masses. The process involves the compression of the breast between two plates on a dedicated mammography machine, which serves to flatten the breast tissue. This compression is crucial as it not only evens out the dense breast tissue but also stabilizes the breast, allowing for clearer and higher-quality images to be captured. The images obtained from this procedure can reveal the presence of tumors or cysts, aiding in the early detection of breast cancer and other breast-related conditions. In addition to the standard imaging, this code includes the use of computer-aided detection (CAD) when performed. CAD employs sophisticated algorithms to analyze the mammographic images, enhancing the radiologist's ability to identify unusual or suspicious areas within the breast tissue. The CAD process typically involves scanning the mammographic films with a laser beam, which converts the analog images into digital data. This digital transformation allows for a more thorough and systematic analysis of the images on a video display, thereby improving diagnostic accuracy. Overall, CPT® Code 77066 encompasses a comprehensive approach to breast imaging, combining traditional mammography techniques with advanced computer technology to support effective diagnosis and treatment planning.

The indications for performing diagnostic mammography, specifically under CPT® Code 77066, include the following:
The procedure for diagnostic mammography under CPT® Code 77066 involves several key steps:
Post-procedure care for patients undergoing diagnostic mammography typically involves minimal recovery time, as the procedure is non-invasive. Patients may resume normal activities immediately following the mammogram. However, they are advised to wait for the radiologist's report, which may take a few days. If any abnormalities are detected, further diagnostic procedures, such as ultrasound or biopsy, may be recommended based on the findings. Patients should also be informed about the importance of regular breast health monitoring and follow-up appointments as necessary.

| 26 | Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number. | X5 | Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician | TC | Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles | GC | This service has been performed in part by a resident under the direction of a teaching physician | GA | Waiver of liability statement issued as required by payer policy, individual case | Q6 | Service furnished under a fee-for-time compensation arrangement by a substitute physician or by a substitute physical therapist furnishing outpatient physical therapy services in a health professional shortage area, a medically underserved area, or a rural area | 77 | Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service. | AQ | Physician providing a service in an unlisted health professional shortage area (hpsa) | X4 | Episodic/focused services: for reporting services by clinicians who provide focused care on particular types of treatment limited to a defined period and circumstance; the patient has a problem, acute or chronic, that will be treated with surgery, radiation, or some other type of generally time-limited intervention; reporting clinician service examples include but are not limited to, the orthopedic surgeon performing a knee replacement and seeing the patient through the postoperative period | GG | Performance and payment of a screening mammogram and diagnostic mammogram on the same patient, same day | 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. | GZ | Item or service expected to be denied as not reasonable and necessary | 76 | Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service. | RT | Right side (used to identify procedures performed on the right side of the body) | 52 | Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use). | Q5 | Service furnished under a reciprocal billing arrangement by a substitute physician or by a substitute physical therapist furnishing outpatient physical therapy services in a health professional shortage area, a medically underserved area, or a rural area | 50 | Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 79 | Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79.
