ICD-9 Codes: (quick reference as suggestions: 174.9 malignant neoplasm of female breast,
unspecified; 233.0 carcinoma in situ of breast; V10.3 personal history of breast cancer; V16.3
family history of breast cancer; V16.9 family history of unspecified malignant neoplasm)
This letter is in regards to my patient and your subscriber, First, Last Name to request full coverage
of medically-indicated genetic testing for hereditary breast and ovarian cancer (HBOC) to be
performed by Ambry Genetics Corporation.
Breast and ovarian cancers are thought to have a hereditary component in up to 10% and up to
25% of cases, respectively; evaluating personal and family histories is a major part of hereditary
cancer risk assessment. Mutations in multiple genes cause HBOC, but mutations in BRCA1/BRCA2
are the most common. Women that carry a BRCA1 or BRCA2 mutation have up to an 87% lifetime
risk to develop breast cancer (compared to 12% in the general population), a 40-60% lifetime risk
for a second primary breast cancer, and a 11-40% lifetime risk to develop ovarian cancer
(compared to 1.6% in the general population.)1 Men that carry a BRCA1 or BRCA2 mutation have an
elevated risk for breast and prostate cancer.1
Significant aspects of my patient’s personal and/or family medical history that suggest a
reasonable probability of HBOC are below:



Based on my patient’s personal and/or family history above, he/she meets the American Society
of Clinical Oncologists (ASCO) and/or National Comprehensive Cancer Network (NCCN)
published guidelines for BRCA1/2 testing. 2,3,4
This genetic testing will help estimate my patient’s risk to develop cancer, and will directly
impact my patient’s medical management. If a mutation is identified, we will adjust medical care
to reduce my patient’s risk of developing (and potentially dying of) an advanced stage cancer. An
aggressive approach following established screening and management guidelines is indicated in
individuals that carry a mutation found on this test. Guidelines suggest the following screening
options:
 For breast cancer: breast self-examinations, clinical breast examinations,
mammogram, ultrasound, MRI, consideration of prophylactic mastectomies, and/or
chemoprevention to reduce a woman’s risk of developing breast cancer.
 For ovarian cancer: risk-reducing salpingo-oophorectomy
 For prostate cancer: PSA and digital rectal exam (DRE)
This test includes full-gene sequencing and deletion/duplication analysis of BRCA1 and BRCA2. Due
to the cancer risks associated with these mutations and the interventions available to reduce these
risks, I am requesting coverage for this testing as medically necessary care and affirm that
my patient has provided informed consent for genetic testing.
A positive test result would confirm a genetic diagnosis and/or risk in my patient, and would
ensure my patient is being managed appropriately. I am specifying Ambry Genetics Corporation
because this laboratory has highly-sensitive and cost-effective testing for hereditary breast cancer,
along with a large database of tested patients to ensure highly validated, accurate, and informative
test interpretation.
I recommend that you support this request for coverage of diagnostic genetic testing for HBOC in
my patient. Genetic testing can take up to several weeks to complete and the laboratory will not bill
until testing is concluded. Therefore, we are requesting that authorization be valid for 3 months.
Thank you for your time and please don’t hesitate to contact me with any questions.
Sincerely,
