    Key Findings

    ESOTERIX, INC operates as a clinical medical laboratory with a pronounced focus on specialty immunology and therapeutic drug monitoring: Medicare billing is heavily dominated by 81490, which generated $8.9M in Medicare revenue and represents 88.5% of this provider's Medicare revenue; that code ranks #1 of 20 providers nationally and is labeled an extreme outlier for national volume. Complementary Medicare activity includes high-ranked assays such as 82397 and therapeutic drug quantitation 80230, indicating lab capabilities for luminescent assays and biologic drug level testing. These code-level patterns point to an operational emphasis on algorithmic disease-activity reporting and specialty immunoassays rather than routine clinical chemistry alone.

    Revenue concentration on Medicare is extremely high: the precomputed figure shows the top 3 Medicare codes account for 92.9% of the provider's total Medicare revenue, which, combined with the $10.3M total Medicare revenue on file, signals material dependency on a very small set of high-reimbursement services. In particular, 81490 alone contributes $8.9M of that sum, concentrating the provider's Medicare financial exposure in a single assay type. Analysts should treat Medicare revenue as highly concentrated around specialty tests when modeling revenue risk or growth.

    By contrast, the provider's Medicaid billing shows a more distributed mix: total Medicaid revenue is $4M and the precomputed top-3 share is 51.5% of Medicaid revenue, with 81220 (CFTR mutation panel) accounting for $1.2M or 34.0% of Medicaid revenue and 86235 and 82306 contributing sizable but smaller shares. This indicates Medicaid business relies significantly on genetic testing and higher-volume endocrine and autoimmune panels, producing a broader portfolio of services compared with the Medicare book. For payers, this suggests different utilization drivers across programs: algorithmic RA scoring and specialty assays in Medicare versus genetic and high-volume hormone/autoimmune testing in Medicaid.

    Payer mix is skewed toward Medicare in scale: the file shows $10.3M in Medicare revenue versus $4M in Medicaid revenue, so Medicare represents the larger portion of reported government payer revenue. This should be considered when assessing commercial contracting leverage or the financial impact of changes in Medicare reimbursement for specialty assays like 81490. Medicaid remains meaningful, however, with a concentrated Medicaid revenue source in 81220 that could affect state-level negotiations or network participation.

    Competitive standing varies sharply by payer and code: nationally for Medicare, ESOTERIX is a dominant outlier on 81490 (ranks #1 of 20, 100th percentile, extreme outlier) and also shows extreme or notably above-typical volumes on codes such as 82397 (ranks #2 of 68, 99th percentile; extreme outlier) and 80230 (ranks #1 of 42, 100th percentile; extreme outlier). For state Medicaid, the provider ranks well for several codes (for example, 81220 ranks #10 of 110 in-state at the 92th percentile and 84403 ranks #9 of 236 at the 97th percentile), but 81490’s Medicaid rank (#2 of 2 in-state) indicates limited state-level presence for that specific RA algorithmic assay. Overall, the provider is a nationally significant node for a few specialized Medicare assays but a more typical high-volume participant across many Medicaid lab codes in-state.

    The code mix implies distinct service lines: heavy Medicare revenue from 81490 and high national ranks on targeted therapeutic drug quantitation codes (80230, 80280) point to a lab organized around algorithmic disease-activity scoring and biologic drug monitoring for immune-mediated conditions. Medicaid revenues concentrated in 81220 (CFTR testing) and large claim counts for endocrine panels (82306, 84403) indicate an additional genetic and endocrine testing offering that drives state-program volume. Together, these patterns are consistent with a lab that combines specialized, proprietary algorithm-based assays with more commoditized high-volume endocrine and genetic testing.

    Statistical outlier signals are strong and should guide due diligence: multiple codes are flagged as extreme outliers or notably above typical national volume (81490: extreme outlier; 82397 and 80230: extreme outliers; several other immunology and hormone assays listed as notably above typical). These outlier labels, coupled with high rank positions, indicate the provider captures atypically large volumes for specific specialty assays at a national level, which may materially affect benchmarking, audit sampling, and contract reviews. Analysts should weight these outlier codes more heavily when assessing utilization trends or compliance risk profiles.

    The entity has long tenure in the NPI registry, enumerated on 2005-12-28 (~21 years ago), which supports interpretation of these billing concentrations as established operational patterns rather than very recent shifts. Longevity combined with concentrated specialty billing suggests these service lines are persistent elements of the provider’s business model rather than transient experiments.
