Positron Emission Tomography (FDG PET) for Oncologic Conditions
(Effective June 11, 2013)
(Rev. 173, Issued: 09-04-14, Effective: Upon Implementation: of ICD-10, Implementation: Upon Implementation of ICD-10)
A. General
FDG (2-[F18] fluoro-2-deoxy-D-glucose) Positron Emission Tomography (PET) is a minimally-invasive
diagnostic imaging procedure used to evaluate glucose metabolism in normal tissue as well as in diseased
tissues in conditions such as cancer, ischemic heart disease, and some neurologic disorders. FDG is an
injected radionuclide (or radiopharmaceutical) that emits sub-atomic particles, known as positrons, as it
decays. FDG PET uses a positron camera (tomograph) to measure the decay of FDG. The rate of FDG
decay provides biochemical information on glucose metabolism in the tissue being studied. As
malignancies can cause abnormalities of metabolism and blood flow, FDG PET evaluation may indicate
the probable presence or absence of a malignancy based upon observed differences in biologic activity
compared to adjacent tissues.
The Centers for Medicare and Medicaid Services (CMS) was asked by the National Oncologic PET
Registry (NOPR) to reconsider section 220.6 of the National Coverage Determinations (NCD) Manual to
end the prospective data collection requirements under Coverage with Evidence Development (CED)
across all oncologic indications of FDG PET imaging. The CMS received public input indicating that the
current coverage framework of prospective data collection under CED be ended for all oncologic uses of
FDG PET imaging.
1. Framework
Effective for claims with dates of service on and after June 11, 2013, CMS is adopting a coverage
framework that ends the prospective data collection requirements by NOPR under CED for all oncologic
uses of FDG PET imaging. CMS is making this change for all NCDs that address coverage of FDG PET for
oncologic uses addressed in this decision. This decision does not change coverage for any use of PET
imaging using radiopharmaceuticals NaF-18 (fluorine-18 labeled sodium fluoride), ammonia N-13, or
rubidium-82 (Rb-82).
2. Initial Anti-Tumor Treatment Strategy
CMS continues to believe that the evidence is adequate to determine that the results of FDG PET imaging
are useful in determining the appropriate initial anti-tumor treatment strategy for beneficiaries with
suspected cancer and improve health outcomes and thus are reasonable and necessary under
§1862(a)(1)(A) of the Social Security Act (the Act).
Therefore, CMS continues to nationally cover one FDG PET study for beneficiaries who have cancers that
are biopsy proven or strongly suspected based on other diagnostic testing when the beneficiary’s treating
physician determines that the FDG PET study is needed to determine the location and/or extent of the tumor
for the following therapeutic purposes related to the initial anti-tumor treatment strategy:
• To determine whether or not the beneficiary is an appropriate candidate for an invasive diagnostic or
therapeutic procedure; or
• To determine the optimal anatomic location for an invasive procedure; or
• To determine the anatomic extent of tumor when the recommended anti-tumor treatment
reasonably depends on the extent of the tumor.
See the table at the end of this section for a synopsis of all nationally covered and non-covered oncologic
uses of FDG PET imaging.
B.1. Initial Anti-Tumor Treatment Strategy Nationally Covered Indications
a. CMS continues to nationally cover FDG PET imaging for the initial anti-tumor treatment strategy for
male and female breast cancer only when used in staging distant metastasis.
b. CMS continues to nationally cover FDG PET to determine initial anti-tumor treatment strategy for
melanoma other than for the evaluation of regional lymph nodes.
c. CMS continues to nationally cover FDG PET imaging for the detection of pre-treatment metastasis
(i.e., staging) in newly diagnosed cervical cancers.
C.1 Initial Anti-Tumor Treatment Strategy Nationally Non-Covered Indications
a. CMS continues to nationally non-cover initial anti-tumor treatment strategy in Medicare
beneficiaries who have adenocarcinoma of the prostate.
b. CMS continues to nationally non-cover FDG PET imaging for diagnosis of breast cancer and initial
staging of axillary nodes.
c. CMS continues to nationally non-cover FDG PET imaging for initial anti-tumor treatment strategy
for the evaluation of regional lymph nodes in melanoma.
d. CMS continues to nationally non-cover FDG PET imaging for the diagnosis of cervical cancer
related to initial anti-tumor treatment strategy.
3. Subsequent Anti-Tumor Treatment Strategy
B.2. Subsequent Anti-Tumor Treatment Strategy Nationally Covered Indications
Three FDG PET scans are nationally covered when used to guide subsequent management of anti-tumor
treatment strategy after completion of initial anti-cancer therapy. Coverage of more than three FDG PET
scans to guide subsequent management of anti-tumor treatment strategy after completion of initial anti-cancer therapy shall be determined by the MACs.
