    Key Findings

    Operational profile: Billing is overwhelmingly concentrated in SARS‑CoV‑2 testing and associated specimen services, with the Medicare top code K1034 (provision of covid-19 test, nonprescription self-administered and self-collected use, fda approved, authorized or cleared) driving the activity. Medicaid claims also show a COVID testing mix (K1034, U0003, G2023, 87811), indicating the lab’s service line is focused on COVID test provision and high-throughput molecular testing rather than a broad panel of clinical lab services.

    Medicare revenue concentration: The provider’s Medicare activity is highly concentrated — precomputed data show the top 3 Medicare codes account for 100.0% of Medicare revenue, and K1034 alone is reported at 1.6M claims, $12 avg paid/claim, $18.8M revenue and listed as 100.0% of this provider’s total Medicare revenue. This indicates a single-code revenue dependency on Medicare-covered COVID test provision.

    Medicaid revenue concentration: On Medicaid the top 3 codes account for 93.2% of the provider’s Medicaid revenue, with K1034 reported at 2.9K claims, $2 avg paid/claim, $5.7K revenue (74.1% of Medicaid revenue), followed by U0003 ($910, 11.8%) and G2023 ($572, 7.4%). Medicaid receipts are therefore also concentrated in COVID-related codes, though spread across a small set rather than a single dominant code.

    Payer mix and scale: This entity is effectively single‑payer at scale — total Medicare revenue is $18.4M versus total Medicaid revenue of $8.4K, showing Medicare is overwhelmingly the revenue source. Medicaid activity exists but is economically immaterial compared with Medicare, so any commercial or state-level strategy would be secondary to the Medicare COVID testing channel.

    Medicare competitive standing: For the Medicare-dominant code K1034 the provider ranks #19 of 30143 providers nationally (100th percentile; extreme outlier), signaling national-scale volume for that specific CPT/HCPCS code far above typical peers. That national ranking identifies the provider as an outlier/dominant volume participant for Medicare‑billed K1034 activity.

    Medicaid competitive standing: The same K1034 code on Medicaid ranks #11 of 59 in-state (83th percentile; typical, unremarkable volume), while other Medicaid codes show low state percentiles (U0003 ranks #300 of 350, 13th percentile; G2023 ranks #335 of 396, 15th percentile; 87811 ranks #487 of 548, 10th percentile). Those ranks indicate the provider is not a statewide leader in laboratory analytic or PCR testing codes despite a notable presence in Medicaid K1034 claims.

    Statistical contrast across payers: There is a striking dichotomy between payers — K1034 is an "extreme outlier" on Medicare but only "typical, unremarkable" on Medicaid in-state rankings. This suggests the provider’s large Medicare volumes for K1034 may reflect a billing footprint or contract structure that does not translate into comparable Medicaid market dominance.

    Tenure and likely timing of growth: The provider’s NPI was enumerated on 2021-09-02 (~5 years ago), which aligns with pandemic-era enrollment and suggests the organization’s rapid growth and revenue profile are likely tied to COVID testing demand established during that period. Tenure information supports an interpretation that the business was established or scaled up to supply pandemic-related testing services.
