The American Medical Association (AMA) Current Procedural Terminology (CPT) codes and Healthcare Common Procedure Coding System (HCPCS) codes listed, are provided for informational purposes only. The codes reflect our interpretation of CPT/HCPCS coding requirements based upon AMA guidelines published annually. CPT/HCPCS codes are provided only as guidance to assist clients with billing. Baylor Genetics strongly recommends that clients confirm CPT/HCPCS codes with their Medicare Administrative Contractor (MAC) or other payer being billed, as requirements may differ. CPT coding is the sole responsibility of the billing party. Baylor Genetics assumes no responsibility for billing errors due to reliance on the CPT codes listed. Please direct any questions regarding CPT coding to the payer being billed.


MitoMetŪPlus aCGH Analysis
Test Information: This array contains 180,000 oligonucleotide probes targeted to both mitochondrial and nuclear genes involved in mitochondrial and metabolic related diseases. Approximately 3200 probes cover the entire 16.6 kb mitochondrial genome. In addition, oligo probes targeted to about 1,600 nuclear genes that are involved in mtDNA biogenesis, maintenance of mitochondrial deoxynucleotide pools, mitochondrial transcription and translation factors, respiratory chain complex assembly and complex subunits, urea cycle disorders, fatty acid oxidation, amino acid metabolism, creatine pathway, progressive familial intrahepatic cholestasis, plus many more, are in the array. This array has detected intragenic nuclear deletions/duplications as small as 200bp to as large as the entire chromosome, and mtDNA deletions larger than 200 bp.

Limitations of Testing:

This analysis will not detect point mutations or small deletion/duplication mutations. For mtDNA deletions of less than 200 bp and for nuclear genes, deletions less than 1 kb may not be detected. Heteroplasmy of less than 15% may not be detected.
Test Details
Test Code: 2000
Special Notes: ONLY Blood is accepted for MitoMetŪPlus aCGH analysis.

MitoMetŪPlus aCGH analysis Indications:

1. MitoMetŪPlus aCGH analysis is recommended for autosomal recessive cases with one heterozygous mutation identified by full gene sequencing.
2. MitoMetŪPlus aCGH analysis is recommended to detect heterozygous intragenic deletions or duplications for autosomal dominant cases negative on full gene sequence analysis.
3. MitoMetŪPlus aCGH analysis is recommended for cases where PCR fails to amplify regions for sequence analysis.
4. MitoMetŪPlus aCGH analysis is recommended for cases where intragenic or multigenic compound heterozygous deletions or duplications are suspected.
5. MitoMetŪPlus aCGH analysis is recommended for cases where there is a failure to detect a mutation in the parent of the individual with an apparently homozygous mutation.
