Procedure code - 77051, 77055, G0204, G0206 - Mammography, Diagnostic

procedure code and description


G0204 -Diagnostic mammography, producing direct digital image, bilateral, all views. - average fee payment -  $150 -$180

77051 - Computer aided detection (computer algorithm analysis of digital image data for lesion detection) with further physician review for interpretation, with or without digitization of film radiographic images, diagnostic mammography


A separate code, G0236, has been created for “Digitization of film radiographic images with computer analysis for lesion detection and further physician review for interpretation, diagnostic mammography (List separately in addition to code for primary procedure)” for computer aided detection, and has been established as the add-on code that can be billed in conjunction with the primary service diagnostic mammography codes 76090, 76091, G0204 or G0206.



Use procedure codes 77051, 77055, 77056, G0204 and G0206 to report only diagnostic mammography. The conditions in the “Covered Diagnoses” section are considered the medical indications for diagnostic mammography.
Patients will present themselves to the health care system under a number of different circumstances, and it will be incumbent upon the patient and treating physician/Non-Physician Practitioner (NPP) to formulate an appropriate imaging treatment plan. In some situations, a screening mammogram will apply, and, in others, a diagnostic mammogram will apply. The treating physician/NPP should ask the following four questions to assist them in determining the most appropriate type of mammogram to order:


  • Do you have breast implants?
  • Is this a follow-up to an abnormal mammogram?
  • Do you have any breast problem, such as a lump or discharge?
  • Have you ever had breast cancer?

No = screening Yes = diagnostic
If any answer to any of the questions above is Yes, the treating physician/NPP should optimally order a diagnostic mammogram. The performing facility (IDTF, hospital, etc.) should perform the test that is ordered by the treating physician/NPP.


Coverage Indications, Limitations, and/or Medical Necessity

    Screening Mammogram

    A screening mammography is a radiologic procedure furnished to a woman without signs or symptoms of breast disease, for the purpose of early detection breast cancer,and includes a physician’s interpretation of the results of the procedure. A screening mammogram does not require a physician’s referral, however, detection of a radiographic abnormality, may prompt the interpreting radiologist to order additional views on the same day. When this is the case, the mammography is no longer considered to be a screening exam and should be reported as a diagnostic mammogram. Radiologists who order additional tests must refer back to the treating physician or qualified non-physician practitioner for his/her UPIN and report back to the treating physician the condition of the patient. No separate reimbursement will be made for additional views. The cost for additional views is included in the cost of the diagnostic mammography service. Screening mammogram(s) (digital and non-digital) for the following indications are allowed:


        Asymptomatic women ages 40 and older are eligible for a screening mammography (digital and non-digital) performed after at least 11 months have passed following the month in which the last screening mammography was performed.

        Women between the ages of 35 and 39 are eligible to receive one baseline screening mammogram.

        Women with breast implants are eligible for screening mammography when the screening mammogram is performed within the aforementioned age and frequency limitations.

        Services will only be allowed if supplied by certified suppliers or FDA-certified mammography centers.


    Limitations


        The screening mammogram must be, at a minimum a two-view exposure (cranio-caudal and a medial lateral oblique view) of each breast.

        Payment may not be made for a screening mammography performed on a woman under age 35.
        Payment may be made for only one screening mammography performed on a woman over age 34, but under age 40.

        Screening mammograms performed prior to 11 months lapsing following the month in which the last screening mammography service was rendered is noncovered.

        Facilities that perform screening mammography services may not release screening mammography x-rays for interpretation to physicians who are not approved under the facility’s certification number unless the patient has requested a transfer of the films from one facility to another for a second opinion or the patient has moved to another part of the country where the next screening mammography will be performed.


    Diagnostic Mammography

    A diagnostic mammography is a radiologic procedure furnished to a man or woman with signs and symptoms of breast disease, or a personal history of breast cancer, or a personal history of biopsy-proven benign breast disease, and includes a physician’s interpretation of the results of the procedure.

    Diagnostic mammogram(s) are allowed for the following indications:

    -the patient is under the care of the referring/ordering physician or qualified non-physician practitioner;

    -there are signs and/or symptoms suggestive of malignancy (mass, some types of spontaneous nipple discharge or skin changes);

    -there are possible radiographic abnormalities detected on screening mammography;

    -there is short interval follow-up (less than one year) necessary for unresolved clinical/radiographic concerns; or

    -follow-up of established history of a malignancy is necessary

    Diagnostic breast evaluation may be indicated in cases of a personal history of malignancy and in cases of benign biopsy-proven breast disease. These diagnoses should not, however, routinely warrant a diagnostic mammography.

    A breast implant does not necessarily imply that a mammogram is diagnostic in nature. Although additional views may be needed, these additional views do not necessarily constitute a diagnostic mammogram, unless there are specific findings that require investigation.

    Medicare Part B covers diagnostic mammography services if they are furnished by a facility that meets the certification requirements of section 354 of the Public Health Service Act (PHS Act), as implemented by 21 CFR part 900, subpart B. As of October 1, 1994, the Mammography Quality Standards Act requires that all mammography centers that bill Medicare be certified by the Food and Drug Administration (FDA). Only FDA-certified mammography centers will be reimbursed.

    A physician (or qualified non-physician practitioner) referral is required for diagnostic mammography. The patient must be under the care of the physician (or qualified non-physician practitioner) who orders the procedure. The order should specify the diagnosis prompting the referral for a diagnostic mammogram.

    Diagnostic mammography should be performed under the direct, on-site supervision of an interpreting physician qualified in mammography. Diagnostic mammography may require that the performing radiologist review the history with the patient, review the prior mammograms, and perform an examination as part of the mammography. Also, the findings of the examination are typically discussed with the patient at the completion of the mammogram. Therefore, if telemammography is being used with digital diagnostic mammography, the radiologist need not be present for the mammography; however, he/she must be available to discuss the history with the patient, examine the patient, and discuss results of the findings of the examination with the patient within an acceptable period of time.

    Limitations

    This policy does not outline complete indications and limitations of breast ultrasound but addresses the limitations of screening mammography with breast ultrasound. (There is no Medicare benefit.)

    Breast ultrasound is not a Medicare preventive services benefit. Therefore, routine breast cancer screening with ultrasound (including patients with dense breast tissue) is not a Medicare covered service. Clinical evidence has not yet demonstrated that routine use of ultrasonography as an adjunct to screening mammography reduces the mortality rate from breast cancer.

    Breast ultrasonography may be reasonable and necessary in addition to a diagnostic mammography for the evaluation of some ambiguous mammographic or palpable masses, focal asymmetry, or dense breast tissue that may represent or mask a mass. Breast ultrasonography may also be performed for non-palpable masses, detected by mammography, to differentiate cysts from solid lesions.

    Breast ultrasound is medically reasonable and necessary as an aid for radiologists to localize breast lesions and in guiding placement of instruments for cyst aspiration and percutaneous breast biopsies. (This is not an all-inclusive list.) If breast ultrasound is medically reasonable and necessary and done on the same day as a screening mammography, the screening mammography becomes diagnostic.

    The request (order) for the ultrasound examination must be originated by a treating physician/NPP. This requirement is not applicable to hospital based radiologists for inpatient or outpatient breast ultrasound.

    A radiologist performing a therapeutic interventional procedure is considered a treating physician. A radiologist performing a diagnostic interventional or diagnostic procedure is not considered a treating physician.

    If the testing facility has no order for breast ultrasound and cannot reach the treating physician/practitioner to obtain a new order for the addition of breast ultrasound when needed and documents this in the medical record, then the testing facility may furnish the additional diagnostic test if all of the following criteria apply:


        The testing center performs the mammography ordered by the treating physician/practitioner;

        The interpreting physician at the testing facility determines and documents that, because of the abnormal result of the diagnostic test performed, an additional diagnostic test is medically necessary;

        Delaying the performance of the additional diagnostic test would have an adverse effect on the care of the beneficiary;

        The result of the test is communicated to and is used by the treating physician/practitioner in the treatment of the beneficiary; and

        The interpreting physician at the testing facility documents in his/her report why additional testing was done.


    Breast sonography should be performed under the general supervision of a physician qualified in breast ultrasonography.


    The ultrasound study must have a permanent written record along with the accompanying set of images in retrievable image storage format. The images and report should become a part of the patient’s permanent medical record.


Notice: This LCD imposes diagnosis limitations that support diagnosis to procedure code automated denials. However, services performed for any given diagnosis must meet all of the indications and limitations stated in this policy, the general requirements for medical necessity as stated in CMS payment policy manuals, any and all existing CMS national coverage determinations, and all Medicare payment rules.

Contractors shall consider a service to be reasonable and necessary if the contractor determines that the service is:

  • Safe and effective.
  • Not experimental or investigational (exception: routine costs of qualifying clinical trial services with dates of service on or after September 19, 2000, which meet the requirements of the clinical trials NCD are considered reasonable and necessary).
  • Appropriate, including the duration and frequency that is considered appropriate for the service, in terms of whether it is:
    • Furnished in accordance with accepted standards of medical practice for the diagnosis or treatment of the patient’s condition or to improve the function of a malformed body member.
    • Furnished in a setting appropriate to the patient’s medical needs and condition.
    • Ordered and furnished by qualified personnel.
    • One that meets, but does not exceed, the patient’s medical need.
    • At least as beneficial as an existing and available medically appropriate alternative.

Bill Type Codes
Contractors may specify Bill Types to help providers identify those Bill Types typically used to report this service. Absence of a Bill Type does not guarantee that the policy does not apply to that Bill Type. Complete absence of all Bill Types indicates that coverage is not influenced by Bill Type and the policy should be assumed to apply equally to all claims.
12X, 13X, 22X, 23X, 85X


Revenue Codes
Contractors may specify Revenue Codes to help providers identify those Revenue Codes typically used to report this service. In most instances Revenue Codes are purely advisory; unless specified in the policy services reported under other Revenue Codes are equally subject to this coverage determination. Complete absence of all Revenue Codes indicates that coverage is not influenced by Revenue Code and the policy should be assumed to apply equally to all Revenue Codes.

Billing and Coding Guidelines
New Modifier GG - Performance and payment of a screening mammogram and diagnostic mammography on the same patient, same day.

NOTE: Modifier GG should be used to show that the diagnostic test performed on the same date as the screening test is appropriate. This modifier is for tracking purposes only. 

HCPCS code G0204, Diagnostic mammography, direct digital image, bilateral, all  views. Payment will be the lesser of the provider's charge or the amount that will be provided for this code in the pricing file. (That amount is 150 percent of the locality specific amount paid under the physician fee schedule for the technical component (TC) of Procedure code 76091, the code for a bilateral diagnostic mammogram.) Twenty percent of the lower of charge or 150 percent of MPFS. 

Deductible is applicable. Coinsurance will equal 20 percent of the lesser of the actual charge or 150 percent of the locality specific payment of Procedure code 76091. 

HCPCS code G0206, Diagnostic mammography, direct digital image, unilateral, all views. Payment will be made based on the same amount that is paid to the provider, under the payment method applicable to the specific provider type (i.e., hospital, rural health clinic, etc.) for Procedure code 76090, the code for a mammogram, one breast. For example, this service, when furnished as a hospital outpatient service, will be paid the amount under the outpatient prospective payment system (OPPS) for Procedure code 76090. Deductible applies. Coinsurance is the national unadjusted coinsurance for the APC wage adjusted for the specific hospital. 

o HCPCS code G0207, Diagnostic mammography, film processed to produce digital image analyzed for potential abnormalities, unilateral, all view. Payment will be based on the same amount that is paid to the provider, under the payment method applicable to the specific provider type (i.e., hospital, rural health clinic) for Procedure code 76090, the code for mammogram, one breast. 

For example, this service, when furnished as a hospital outpatient service, will be paid the amount payable under the OPPS for Procedure code 76090. Deductible applies. Coinsurance is the national unadjusted coinsurance for the APC wage adjusted for the specific hospital.

B. Billing Requirements.--Only one screening mammogram, either 76092 or G0202 may be billed in a calendar year. Therefore, advise your providers not to submit claims reflecting both a film screening mammography (76092) and a digital screening mammography G0202. Also advise your providers not to submit claims reflecting HCPCS codes 76090 or 76091 (diagnostic mammography-film) and G0204 or G0206 (diagnostic mammography-digital). Deny the claim when both a film and digital screening or diagnostic mammography are reported. However, a screening and diagnostic mammography can be billed together.



Diagnostic Mammography

A diagnostic mammography is a radiological mammogram and is a covered diagnostic test under the following conditions:
• A patient has distinct signs and symptoms for which a mammogram is indicated;
• A patient has a history of breast cancer

Prior to April 1, 2003, the MQSA file showed all facilities that are certified to perform film screening and diagnostic mammograms. After April 1, 2003, the file shows a new Record Type with two indicators, “1” for film and “2” for digital to determine which mammograms the facility is certified to perform.

Effective for claims with dates of service January 1, 2015 and later, HCPCS code 77063, “Screening Digital Breast Tomosynthesis, bilateral, must be billed in conjunction with the primary service mammogram code G0202.

Medicare will pay for a diagnostic mammogram when one of the following conditions is met:
• A patient has distinct signs and symptoms for which a mammogram is indicated
• A patient has a history of breast cancer
• A patient is asymptomatic but, on the basis of the patient’s history and other factors the physician considers significant, the physician's judgment is that a mammogram is appropriate
