Annual Notice

2024 Annual Notice to Physicians

This letter serves as an annual notice on updates regarding the ordering and processing of clinical laboratory tests performed by Guardant Health, Inc. Guardant may update you more than once a year if there are material changes to the testing panel, such as FDA approval or a new product release.

Please review the attached information in this notice and contact Client Services at 855-722-7335 if you have any questions.

Medical Necessity

Medicare pays for services that are reasonable and necessary and meet specified Medicare coverage criteria for the beneficiary’s unique medical condition.

As a participating Medicare provider, Guardant Health has the responsibility to make good faith efforts to ensure that all tests requested are performed and billed in a manner that is consistent with federal and state statutes and regulations. The OIG takes the position that ordering providers authorized by law to order clinical laboratory tests for Medicare beneficiaries share the burden of ensuring that only medically necessary services are ordered and billed to Federally funded programs. Providers who submit false claims may be subject to sanctions or remedies available under civil and administrative law.

Guardant attempts to have a comprehensive set of attestations on the Test Requisition Form (TRF) to determine the coverage status for Medicare services. Completion of the entire TRF enables appropriate determination of coverage for rendered services.

Medicare Coverage Determinations

Shield™ is FDA approved for CRC cancer screening and meets the coverage criteria for Medicare defined in NCD 210.3. NCDs have sections describing what medical conditions are covered and the ICD-10 codes that are covered. All clinical orders sent to Guardant Health must include at least one ICD-10 code and should include all appropriate ICD-10 codes that are applicable to the testing that is being ordered.

The Shield™ test is a qualitative, in vitro diagnostic test intended to detect colorectal cancer derived alterations in cell-free DNA from blood collected in the Guardant Shield Blood Collection Kit. Shield is indicated for colorectal cancer screening in individuals at average risk for the disease, age 45 years or older. Patients with a positive result should be followed by colonoscopy.

Important Product Information

Intended Use

The Shield™ test is a qualitative, in vitro diagnostic test intended to detect colorectal cancer derived alterations in cell-free DNA from blood collected in the Guardant Shield Blood Collection Kit.
Shield is indicated for colorectal cancer screening in individuals at average risk for the disease, age 45 years or older. Patients with a positive result should be followed by colonoscopy. Shield is not a replacement for diagnostic colonoscopy or for surveillance colonoscopy in high-risk individuals. This test is performed at Guardant Health, Inc.

Precaution: Based on data from clinical studies, Shield has limited detection (55%-65%) of Stage I colorectal cancer and does not detect 87% of precancerous lesions. One out of 10 patients with a negative Shield result may have a precancer that would have been detected by a screening colonoscopy. Shield demonstrated high detection of Stage II, III, and IV colorectal cancer.

Limitations and Other Important Information: The Shield test is not indicated for patients that have personal history of colorectal cancer, adenomas, or other related cancers; or those who had a positive result on another colorectal cancer screening method within the last six months, have been diagnosed with a condition associated with high risk for colorectal cancer such as Inflammatory Bowel Disease (IBD), chronic ulcerative colitis (CUC), Crohn’s disease; or who have a family history of colorectal cancer, or certain hereditary syndromes. Providers should discuss the most appropriate screening test to use with patients depending on their medical history and individual circumstances. Shield may produce a false negative or false positive result. A false negative result may occur when the Shield test does not detect a colorectal tumor signal while a colonoscopy identifies a colorectal cancer. A negative result does not guarantee the absence of colorectal cancer or advanced adenoma, and patients should continue participating in colorectal cancer screening programs at the appropriate guideline-recommended intervals. A false positive result may occur when the Shield test generates a positive result while a colonoscopy will not find colorectal cancer or advanced adenoma.
