Why are Medicare and Medicaid shown separately instead of combined?

They come from two different CMS data sources with no shared claim identifier, so they can't be reconciled into one number without double-counting or guessing. Every table and chart on this page keeps them fully separate.

Why is there no private/commercial revenue figure?

Private and commercial payer data comes from Transparency in Coverage files, which only publish negotiated rates — not claims or utilization volume. Without a volume figure, no revenue number can be computed for any provider from that data.

What does "Rank" mean in the Competitive Analysis & Benchmarks tables?

For a given CPT/HCPCS code, it's this provider's position by claims volume among all providers billing that same code at that geography level (State, National, or California for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to California only?

Medicaid is administered per-state with no single national fee schedule, so a state or national comparison the way Medicare has one isn't available. California (this provider's own state) is the only grouping that's conceptually meaningful.

Why are the numbers rounded to the nearest 10?

To avoid implying more precision than the underlying data supports at a single-provider level. Ratios are kept precise since they're a relative comparison, not a volume or dollar figure.

How current is this data?

The Medicare and Medicaid tables are both single current snapshots, not refreshed on a recurring schedule yet.

Key Findings

JON KELLER is effectively a Medicare-focused laboratory service provider: lifetime Medicare revenue is $6.4M while there is no Medicaid billing on file, so the practice operates as a single-payer (Medicare) revenue stream at scale. The NPI was enumerated 2006-10-05 (~20 years ago), indicating long tenure and an established billing footprint in Medicare.

Revenue concentration is substantial within a narrow set of laboratory/phlebotomy services: the top 3 Medicare codes account for 37.4% of this provider's total Medicare revenue, with 36415 contributing $866.9K (18.0%), 80053 contributing $508.1K (10.6%), and 80061 contributing $422.1K (8.8%). This concentration points to heavy reliance on venous blood collection and routine chemistry panels for a large share of income.

The code mix and dollar volumes identify a high-throughput outpatient laboratory and phlebotomy operation: the highest-revenue code is 36415 (blood draw) at $866.9K, and the next two are broad diagnostic panels 80053 (CMP) at $508.1K and 80061 (lipid panel) at $422.1K. A broad array of other clinical lab tests with meaningful revenue — e.g., 84443 TSH ($379.7K), 82306 vitamin D ($320K), and 83036 A1C ($266.5K) — further support the profile of a full-service clinical laboratory processing routine and chronic disease monitoring panels.

Competitive standing is nationally dominant for many routine lab codes: 36415 ranks #40 of 86467 providers nationally (100th percentile; extreme outlier) and 80053 ranks #64 of 26416 providers nationally (100th percentile; notably above typical national volume). Multiple additional high-revenue tests (e.g., 85025, 80048, 83036) also sit in the 99–100th percentile or are described as “notably above typical national volume” or “extreme outlier,” indicating this provider operates at volumes well above typical peers for common lab services.

Although many clinical chemistry and hematology panels are extreme or notable outliers, the provider’s participation in SARS-CoV-2 PCR testing was more modest: U0003 generated $147.7K (3.1% of Medicare revenue) and ranks at the 88th percentile nationally, while U0005 produced $49.2K (1.0% of Medicare revenue) at the 86th percentile. This suggests the practice added COVID testing capacity but did not lead the nation in high-throughput SARS-CoV-2 testing compared with its dominance in routine phlebotomy and metabolic panels.

The breadth of diagnostic services includes endocrine, vitamin, infectious disease, and microbiology testing beyond routine panels — examples include 84443 TSH ($379.7K), 82306 vitamin D ($320K), 84153 PSA ($137.1K), and 86481 TB immune assay ($93.4K). These diversified test lines indicate the lab supports chronic disease monitoring (A1C, lipid, CMP), preventive screening (PSA, TSH), and specialized diagnostics (TB, parathyroid hormone, cultures), consistent with a full-service outpatient reference or hospital-affiliated lab.

High-volume, low-fee claims are a notable operational feature: many top codes show very large claim counts with modest average paid/claim (for example, 36415 at 108.4K claims with $8 avg paid/claim, 80053 at 50.8K claims with $10 avg paid/claim, and 85025 at 52.1K claims with $8 avg paid/claim). This pattern is typical of centralized phlebotomy and automated lab testing operations where scale of specimen processing drives revenue rather than high per-test reimbursement.

Concentration in a single payer creates financial exposure to Medicare policy changes: with $6.4M in Medicare revenue and no Medicaid billing on file, payer mix is highly concentrated and any Medicare reimbursement changes for high-volume codes such as 36415, 80053, and 80061 (the top three comprising 37.4% of Medicare revenue) would disproportionately affect overall revenue. Analysts should note both the provider’s strong national volume position on key lab services and the corresponding dependency on those Medicare-paid tests.
