General Genetic Testing Criteria

Genetic Testing Not Covered

State Specific Definition

Genetic Services for Children

Genetic Counseling Requirement

Instructions and application materials for genetic counselor licensure can be found at: https://www.lsbme.la.gov/content/application-instructions-initial-licensure-genetic-counselor

Counseling is required before and after all genetic testing. Counseling, at a minimum, must consist of the following and be documented in the beneficiary’s medical record:

  • Obtaining a structured family genetic history;
  • Genetic risk assessment; and
  • Counseling of the beneficiary and family about diagnosis, prognosis, and treatment.

When performed by licensed genetic counselors, services are reimbursed using the procedure code
specific to genetic counseling. Reimbursement for this service is “incident to” the services of a
supervising physician and is limited to no more than 90 minutes on a single day of service.
When performed by providers other than licensed genetic counselors, an applicable evaluation and
management code must be used.

LR 32:319 et seq.

Metabolic Formula Coverage & Criteria

Louisiana Medicaid covers and considers medically necessary enteral formulas for beneficiaries of all ages without PA when the beneficiary has a diagnosis of an inborn error of metabolism made by a physician board certified in medical genetics or an advanced practice registered nurse collaborating with, or a physician assistant supervised by, a physician board certified in medical genetics. Enteral formulas are also covered and considered medically necessary without PA if a beneficiary is suspected of having an inborn error of metabolism, pending the results of a definitive evaluation, when such enteral formula is needed to prevent morbidity. In this case, the
enteral formula does not need to be ordered by a specialist. To provide documentation of medical necessity, the Genetic Disease program must maintain a completed Request for Enteral Formula for Inborn Errors of Metabolism order form in the beneficiary’s record which is signed and dated by the appropriate ordering provider. Claims for enteral formula are subject to post-payment review and non-compliance with this policy may result in recoupment of overpayments.

Prior Authorization Requirements

Genetic testing must be prior approved by the fiscal intermediary’s Prior Authorization Unit or the managed care organization.

Microarray Testing

Newborn Screening

Newborn screening is covered by Louisiana Medicaid.

Panel Testing

Pharmacogenetic Testing

Prenatal Testing Offered

Non-Invasive Prenatal Testing (NIPT) is a genetic test which uses maternal blood that contains cell-free fetal deoxyribonucleic acid (DNA) from the placenta. NIPT is completed during the prenatal period of pregnancy to screen for the presence of some common fetal chromosomal abnormalities. Common types of chromosomal abnormalities (aneuploidies and microdeletions) in fetuses include:

  • Trisomy 21 (Down syndrome);
  • Trisomy 18 (Edwards syndrome); and
  • Trisomy 13 (Patau syndrome).

NIPT is considered medically necessary once per pregnancy for pregnant women over the age of 35, and for women of all ages who meet one or more of the following high-risk criteria:

  1. Abnormal first trimester screen, quad screen or integrated screen;
  2. Abnormal fetal ultrasound scan indicating increased risk of aneuploidy;
  3. Prior family history of aneuploidy in first (1st) degree relative for either parent;
  4. Previous history of pregnancy with aneuploidy; and
  5. Known Robertsonian translocation in either parent involving chromosomes 13 or 21.

NOTE: 1st degree relative is defined as a person’s parent, children, or sibling.
NIPT is NOT covered for women with multiple gestations.

Whole Exome Sequencing

Rapid whole genome sequencing is considered medically necessary for infants less than 12 months of age who are receiving inpatient hospital services in an intensive care or pediatric unit if they meet the following criteria:

  1. Are suspected of having a rare genetic condition that is not diagnosable by standard methods;
  2. Have symptoms that suggest a broad differential diagnosis that requires an evaluation by multiple genetic tests if advanced molecular techniques, including, but not limited to, traditional whole genome sequencing, rapid whole genome sequencing, and other genetic and genomic screening, are not performed;
  3. Timely identification of a molecular diagnosis is necessary to guide clinical decision making, and the advanced molecular techniques including, but not limited to, traditional whole genome sequencing, rapid whole genome sequencing, and other genetic and genomic screening results may guide the treatment or management of the infant’s condition;
  4. Have an illness with at least one of the following features:
    1. Multiple congenital anomalies;
    2. Specific malformations highly suggestive of a genetic etiology;
    3. Abnormal laboratory tests suggesting the presence of a genetic disease or complex metabolic phenotype like, but not limited to, an abnormal newborn screen, hyperammonemia, or lactic acidosis not due to poor perfusion;
    4. Refractory or severe hypoglycemia;
    5. Abnormal response to therapy related to an underlying medical condition affecting vital organs or bodily systems;
    6. Severe hypotonia;
    7. Refractory seizures;
    8. A high-risk stratification on evaluation for a brief resolved unexplained event with any of the following:
      1. A recurrent event without respiratory infection,
      2. A recurrent witnessed seizure-like event, or
      3. A recurrent cardiopulmonary resuscitation;
    9. Abnormal chemistry levels including, but not limited to, electrolytes, bicarbonate, lactic acid, venous blood gas, and glucose suggestive of inborn error of metabolism;
    10. Abnormal cardiac diagnostic testing results suggestive of possible channelopathies, arrhythmias, cardiomyopathies, myocarditis, or structural heart disease; or
    11. Family genetic history related to the infant’s condition.

Other Tests Covered

Other Information

Genetic testing for a particular disease should generally be performed once per lifetime; however, there are rare instances in which testing may be performed more than once in a lifetime (e.g.,
previous testing methodology is inaccurate or a new discovery has added significant relevant mutations for a disease).
