    CPT 81402: Molecular Pathology Tier 2 Level 3 Technical Test

    Commercial payers pay $222 on average nationally for this procedure.

    CPT code 81402 describes a molecular pathology Tier 2, Level 3 technical laboratory service in which the lab analyst performs the technical component of a specific genetic analysis; the service type is molecular diagnostic technical test and the typical site of service is a clinical molecular laboratory or hospital laboratory where sequencing, amplification, or other molecular techniques are conducted to generate analyzable genetic data.

    National Reimbursement Benchmarks

    National commercial reimbursement centers on BUCA’s average commercial rate of $222.50 for CPT 81402, with individual payers showing notable spread around that midpoint. Blue Cross Blue Shield displays the widest middle spread (P75–P25 = $125.10), reflecting greater variability in negotiated commercial rates, while Aetna’s middle 50% is much tighter (P75–P25 = $11.20), indicating more clustered pricing. Cigna and UnitedHealth Group show moderate dispersion (Cigna P75–P25 = $121.75; UnitedHealth Group P75–P25 = $87.70), and BUCA’s IQR (P75–P25 = $106.30) sits between those extremes.

    Mean rates also vary: Blue Cross Blue Shield and BUCA have higher averages ($290.80 and $222.50 respectively), while Aetna and UnitedHealth Group have lower means ($87.20 and $119.90 respectively), with Cigna in the middle at $187.10. This mix of mean levels and interquartile spreads highlights that some payers price more consistently at lower levels and others show both higher averages and greater variability in commercial reimbursement for this code.

    Clinical & Coding Specifications

    Clinical Context

    A 28-year-old pregnant patient is referred to a molecular diagnostics laboratory after an abnormal prenatal screen; the ordering provider requests targeted Tier 2, Level 3 molecular testing to evaluate suspected chromosomal or metabolic abnormalities. A specimen (blood or amniotic fluid) is collected in the outpatient obstetrics clinic and sent to the reference molecular pathology lab. The lab analyst performs the technical component of the specified genetic analysis using validated molecular methods (eg, targeted sequencing, multiplex PCR, or copy-number assessment) to detect single-gene variants, small exon-level changes, or defined panels compatible with a Level 3 molecular pathology code. The laboratory’s technical workflow includes specimen accessioning, nucleic acid extraction, assay setup, instrument run, data processing, and generation of raw technical data. The laboratory technologist documents run metrics and prepares the technical component (laboratory-only) report and raw data files; the final interpretive report and clinical correlation are completed by a Molecular Genetic Pathology physician. Typical sites of service include outpatient clinics, hospital outpatient departments, and reference diagnostic laboratories. Common clinical indications align with screening for genetic and chromosomal anomalies (Z13.79), evaluation of an unspecified chromosomal abnormality (Q99.9), metabolic disorder workup (E88.9), investigation of abnormal urine findings (R82.90), or follow-up of abnormal liver function studies (R94.5).

    Description
    Relationship to This Procedure
    81403Molecular pathology procedure, Level 4 (eg, analysis of single exon by DNA sequence analysis, analysis of >10 amplicons using multiplex PCR in 2 or more independent reactions, mutation scanning or duplication/deletion variants of 2–5 exons)Higher-complexity molecular analysis that may be ordered for broader testing or follow-up when Level 3 results are inconclusive or additional exons/amplicons require analysis.
    81401Molecular pathology procedure, Level 2 (eg, 2–10 variants in a single gene)Lower-complexity targeted molecular test often used when fewer variants are interrogated; may be billed instead of or in addition to Level 3 testing depending on assay scope.
