Lifetime revenue by payer source (source: CMS Medicare & Medicaid claims data)
| Payer Source | Total Paid |
|---|---|
| Medicare | $2.6M |
| Medicaid | $4.7K |
Medicare dominates this provider’s public payer mix: reported lifetime Medicare revenue is $2.6M versus only $4.7K in Medicaid, making the practice effectively Medicare‑centric rather than balanced across both programs. The disparity in scale suggests most clinical activity and revenue collection occurs through Medicare rather than Medicaid.
The code mix indicates an anatomic/clinical pathology operation focused on surgical pathology and immunohistochemistry: the top Medicare drivers are 88305 (surgical pathology level IV), 88312 (special stains for microorganisms), and 88342 (initial single antibody IHC). These codes point to a lab that processes high volumes of excised specimens and performs substantial special stain and IHC interpretation work.
Revenue concentration on Medicare is extremely high: the provider’s top three Medicare CPT/HCPCS codes account for 90.5% of Medicare revenue, with 88305 generating $1.6M (60.2% of Medicare revenue), 88312 $583K (22.5%), and 88342 $204.6K (7.9%). This concentration indicates that a small set of pathology services drives nearly all Medicare receipts.
Medicaid revenue is negligible and also highly concentrated: the top three Medicaid codes account for 100.0% of Medicaid revenue, with 88305 contributing $4.3K (90.7%) and 88312 $437 (9.3%). Given the $4.7K total Medicaid lifetime revenue, Medicaid is not a material line of business for this provider.
National competitive standing on Medicare shows exceptional volume for key pathology services: 88305 ranks #37 of 14580 providers (100th percentile; extreme outlier, far above typical national volume for this code), 88312 ranks #20 of 6966 providers (100th percentile; extreme outlier, far above typical national volume), and 88342 ranks #60 of 11370 providers (99th percentile; extreme outlier, far above typical national volume). These rankings characterize the provider as a major national-volume outlier for those specific pathology codes.
By contrast, in-state Medicaid rankings are modest to low: 88305 ranks #50 of 56 providers in-state (11th percentile; typical, unremarkable volume) and 88312 ranks #21 of 24 (13th percentile; typical, unremarkable volume). This split indicates the provider’s market prominence is concentrated in the Medicare population and does not translate into broad Medicaid volume within the state.
Operational throughput signals are clear from claim counts and per-claim payments: Medicare shows 30.6K claims for 88305 at $51 avg paid/claim and 6.9K claims for 88312 at $84 avg paid/claim, reflecting high specimen throughput with relatively low per-claim unit prices typical of high-volume pathology processing. Those volumes are consistent with a specimen-processing center or centralized pathology practice that relies on scale for revenue.
The provider has long tenure in the NPI registry (enumerated 2006-08-05, approximately 20 years), indicating an established presence that likely underpins the high sustained Medicare volumes; this longevity supports the interpretation of sustained, high-volume pathology services rather than a short-term billing anomaly.
