The percentage of clinically node negative (clinical stage T1N0M0 or T2N0M0) breast cancer patients before or after neoadjuvant systemic therapy, who undergo a sentinel lymph node (SLN) procedure
This measure is to be submitted each time a procedure is performed during the performance period for patients age 18 years and older who are operated upon for invasive breast cancer that are clinically node negative (clinical stage T1N0M0 or T2N0M0) before or after neoadjuvant systemic therapy. This measure may be submitted by Merit-based Incentive Payment System (MIPS) eligible clinicians who perform the quality actions described in the measure based on the services provided and the measure-specific denominator coding.
Measure Submission Type:
Measure data may be submitted by individual MIPS eligible clinicians, groups, or third party intermediaries. The listed denominator criteria are used to identify the intended patient population. The numerator options included in this specification are used to submit the quality actions as allowed by the measure. The quality-data codes listed do not need to be submitted by MIPS eligible clinicians, groups, or third party intermediaries that utilize this modality for submissions; however, these codes may be submitted for those third party intermediaries that utilize Medicare Part B claims data. For more information regarding Application Programming Interface (API), please refer to the Quality Payment Program (QPP) website.

Clinically Node Negative (T1N0M0 or T2N0M0) Invasive Breast Cancer Before or After Neoadjuvant Systemic Therapy: G9911
Patients who undergo a SLN procedure
Performance Met: Sentinel lymph node biopsy procedure performed (G8878)
Denominator Exception: Documentation of reason(s) sentinel lymph node biopsy not performed (e.g., reasons could include but not limited to; non-invasive cancer, incidental discovery of breast cancer on prophylactic mastectomy, incidental discovery of breast cancer on reduction mammoplasty, pre-operative biopsy proven lymph node (LN) metastases, inflammatory carcinoma, stage 3 locally advanced cancer, recurrent invasive breast cancer, clinically node positive after neoadjuvant systemic therapy, patient refusal after informed consent, patient with significant age, comorbidities, or limited life expectancy and favorable tumor; adjuvant systemic therapy unlikely to change) (G8880)
Performance Not Met: Sentinel lymph node biopsy procedure not performed, reason not given (G8882)
A sentinel lymph node (SLN) procedure is defined as a method of axillary or other regional lymph node assessment that requires either a radioisotope and/or blue dye injection in the breast with subsequent identification of radioactive or blue stained node(s) in the axilla or other lymph node basin. There is level one evidence that breast cancer SLN biopsy is as accurate as axillary dissection for breast cancer staging and is associated with less morbidity than routine axillary dissection.
Clinical Recommendation Statements
The current body of reported surgical experience shows that SLN biopsy is suitable for virtually all clinically nodenegative T1-2 invasive breast cancers. (The American Society of Breast Surgeons, 2010)
