CPT 0215U: Genomic Unity® Exome Plus Analysis

CPT code 0215U is a Proprietary Laboratory Analyses (PLA) code for the Genomic Unity® Exome Plus Analysis – Comparator from Variantyx Inc. It covers a targeted genomic laboratory service that sequences and analyzes the exome plus mitochondrial DNA from a relative to construct a reference exome for comparison with a proband’s exome to evaluate rare constitutional or genetic disorders. As a PLA code, 0215U applies to a single manufacturer’s proprietary test and is used for precise identification and tracking of this specific assay.

This summary addresses national payer relevance and coverage considerations. Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find benchmarks on how PLA codes like 0215U are categorized and reimbursed nationally, discussion of clinical context for exome-plus comparator testing in familial genetic evaluation, and policy considerations affecting proprietary laboratory tests.

The publication provides: (1) a concise clinical description and coding guidance for billing staff; (2) payer coverage patterns and coding benchmarks where available; and (3) policy and utilization context for proprietary genomic tests.

Billing Code Overview

CPT code 0215U is a Proprietary Laboratory Analyses (PLA) code reported for the Genomic Unity® Exome Plus Analysis – Comparator from Variantyx Inc. The code describes a laboratory service that analyzes the exome and mitochondrial DNA from a relative of a proband to create a reference exome that can be compared to the proband patient’s exome to evaluate rare constitutional or genetic disorders.

Service Type: Genomic laboratory test — exome and mitochondrial DNA comparator analysis

Typical Site of Service: Clinical molecular genetics laboratory or reference laboratory

Data not available in the input.

Clinical Context

A proband (index) patient presents with a suspected rare constitutional or genetic disorder characterized by unexplained developmental delay, congenital anomalies, neuromuscular symptoms, or multisystem findings. Prior clinical evaluation, family history, and initial genetic testing are inconclusive. A relative (often a parent or sibling) undergoes exome plus mitochondrial DNA sequencing to generate a reference exome. The laboratory performs the Genomic Unity® Exome Plus Analysis – Comparator (0215U) on the relative’s sample and compares the relative’s exome and mitochondrial DNA to the proband’s exome to help distinguish inherited benign variants from de novo or pathogenic variants in the proband.

Typical clinical workflow:

Referral from a geneticist, pediatric neurologist, or medical genetic counselor for trio/relative-based analysis.
Collection of blood or saliva samples from the proband and the selected relative; sample accessioning and chain-of-custody documented.
Laboratory performs exome sequencing including nuclear exome and mitochondrial DNA for the relative to produce a high-quality reference exome and mitochondrial sequence.
Bioinformatic comparison and variant interpretation using the relative’s reference exome to prioritize candidate variants in the proband, with reporting of likely pathogenic, pathogenic, and variants of uncertain significance relevant to the clinical phenotype.
Result delivery to ordering clinician for integration with clinical findings and family counseling.
