    Key Findings

    Payer mix is Medicaid‑dominant: the provider reports $121.8M in lifetime Medicaid revenue versus $27.3M in lifetime Medicare revenue, indicating a substantially larger Medicaid footprint in absolute dollars and that Medicaid accounts for the bulk of billed volume and revenue for this entity. This profile suggests the organization operates primarily as a high‑volume Medicaid lab provider in its state rather than as a Medicare‑focused supplier.

    Service mix points to a high‑throughput clinical laboratory with both routine outpatient chemistry/phlebotomy and large infectious‑disease/STI testing operations. On the Medicare side the largest revenue drivers are codes tied to phlebotomy and routine panels—36415, 80053, and 80061—while Medicaid shows massive volumes in molecular infectious testing and drug/toxicology work (U0003, G0480, 80307), consistent with a network laboratory that handles both routine chronic‑care monitoring and high volumes of public‑health and screening tests.

    Medicare revenue is concentrated: the top three Medicare codes account for 36.4% of total Medicare revenue, led by 36415 (12.6% of Medicare revenue), 80053 (12.3%), and 80061 (11.4%). Each of those codes appears as a primary operational activity for the practice (phlebotomy, CMP, lipid panel), indicating routine outpatient lab work constitutes a large, stable share of the provider’s Medicare business.

    Medicaid revenue is even more concentrated at the top: the top three Medicaid codes account for 47.7% of total Medicaid revenue, driven primarily by U0003 (32.1% of Medicaid revenue), G0480 (8.0%), and 80307 (7.6%). U0003 alone represents a single code responsible for nearly a third of Medicaid revenue, signaling heavy dependence on high‑volume SARS‑CoV‑2 testing in the state Medicaid population.

    Competitive standing — national Medicare: the provider is an unusually large national claimant on many common lab codes. Examples include 36415 (rank #20 of 86467 providers nationally, 100th percentile; extreme outlier), 80053 (rank #26 of 26416, 100th percentile; extreme outlier), and 80061 (rank #24 of 21671, 100th percentile; extreme outlier), which together indicate the provider is a high‑volume national outlier for routine lab services.

    Competitive standing — in‑state Medicaid: the provider is a dominant in‑state player for many Medicaid codes, frequently ranking #1 in Maryland and labeled an extreme outlier for state volume. Illustrative in‑state leadership includes U0003 (rank #1 of 83 providers, 100th percentile; extreme outlier), G0480 (rank #1 of 58 providers, 100th percentile; extreme outlier), 80307 (rank #1 of 159 providers, 100th percentile; extreme outlier), and numerous routine panels that also rank #1 in‑state, showing broad market share across infectious, toxicology and routine lab services.

    The provider’s billing pattern shows a significant public‑health and STI screening footprint under Medicaid: very large claim counts for infectious and sexual‑health testing (U0003 376.5K claims; 87491 239K claims; 87591 238.8K claims; 87389 183.7K claims) and high HIV and hepatitis screening activity (86803 120.2K claims). These volumes are consistent with a laboratory performing state‑scale screening and outbreak response work in addition to routine diagnostics.

    The NPI shows a long tenure: enumerated 2006-11-29 (~20 years ago), indicating an established operation. Coupled with the high national and in‑state ranks for many codes and the large lifetime revenues reported, the data are consistent with a mature, high‑capacity clinical laboratory infrastructure rather than a small or recently established clinic.
