Note:

 The purpose of the SNP microarray test is to look for the presence of mutations, hereby called "Copy Number Variation" or CNV and "Loss of Heterozygosity" or LOH throughout the entire genomic DNA. This type of genetic testing may be used to confirm a diagnosis in a person affected by an illness or may be used in individuals who have a family history of a genetic condition to determine presence or not of disease mutations and determine disease predisposition.

Review 2/28/2013by Dr. Dong, Theresa Friloux

When ordering tests for which Medicare or Medicaid reimbursement will be sought, physicians should only order tests that are medically necessary for the diagnosis or treatment of the patient.  Components of the organ or disease panels may be ordered individually.  The diagnostic information must substantiate all tests ordered and must be in the form of an ICD-9 code or its verbal equivalent.
