Medical Guideline Disclaimer Property of EmblemHealth. All rights reserved.
The treating physician or primary care provider must submit to EmblemHealth the clinical evidence that the member meets the criteria for the treatment
or surgical procedure. Without this documentation and information, EmblemHealth will not be able to properly review the request preauthorization or
post-payment review. The clinical review criteria expressed below reflects how EmblemHealth determines whether certain services or supplies are
medically necessary. This clinical policy is not intended to pre-empt the judgment of the reviewing medical director or dictate to health care providers how
to practice medicine. Health care providers are expected to exercise their medical judgment in rendering appropriate care. Health care providers are
expected to exercise their medical judgment in rendering appropriate care.
EmblemHealth established the clinical review criteria based upon a review of currently available clinical information (including clinical outcome studies in
the peer reviewed published medical literature, regulatory status of the technology, evidence-based guidelines of public health and health research
agencies, evidence-based guidelines and positions of leading national health professional organizations, views of physicians practicing in relevant clinical
areas, and other relevant factors). EmblemHealth expressly reserves the right to revise these conclusions as clinical information changes and welcomes
further relevant information. Each benefit program defines which services are covered. The conclusion that a particular service or supply is medically
necessary does not constitute a representation or warranty that this service or supply is covered and/or paid for by EmblemHealth, as some programs
exclude coverage for services or supplies that EmblemHealth considers medically necessary.
If there is a discrepancy between this guideline and a member's benefits program, the benefits program will govern. Identification of selected brand names
of devices, tests and procedures in a medical coverage policy is for reference only and is not an endorsement of any one device, test or procedure over
another. In addition, coverage may be mandated by applicable legal requirements of a state, the Federal Government or the Centers for Medicare &
Medicaid Services (CMS) for Medicare and Medicaid members. All coding and web site links are accurate at time of publication.
EmblemHealth may also use tools developed by third parties, such as the MCG™ Care Guidelines, to assist us in administering health benefits. The MCG™
Care Guidelines are intended to be used in connection with the independent professional medical judgment of a qualified health care provider and do not
constitute the practice of medicine or medical advice. EmblemHealth Services Company, LLC, has adopted this policy in providing management,
administrative and other services to EmblemHealth Plan, Inc., EmblemHealth Insurance Company, EmblemHealth Services Company, LLC, and Health
Insurance Plan of Greater New York (HIP) related to health benefit plans offered by these entities. All of the aforementioned entities are affiliated

Background
Fetal surgery (also referred to as in-utero or prenatal surgery) is a complex surgical intervention performed on the

Bladder outlet obstruction (BOO)
Congenital diaphragmatic hernia (CDH)
