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 Arkansas for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to Arkansas 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. Arkansas (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

Specialty and service mix reflect a high-volume anatomic pathology practice: the provider’s top revenue drivers are immunohistochemistry and surgical pathology codes (88341, 88342, 88305) and multiple special-stain codes (88313, 88312). The presence of large-volume antibody stain codes (88341 and 88342) together with the level IV surgical pathology code 88305 indicates the operation performs both technical slide work and substantive pathologist interpretation as core services.

Medicare revenue is concentrated in a narrow set of services: the provider reports $1.7M in total Medicare revenue and the precomputed top-three share shows 73.2% of that Medicare revenue comes from the three highest-revenue codes. Individually, 88341 accounts for $625.8K (36.6%), 88305 for $327.4K (19.1%), and 88342 for $299.8K (17.5%), pointing to a revenue profile dominated by a few pathology procedures.

This provider is effectively single-payer with respect to public insurance: there is no Medicaid billing on file, so Medicare represents the documented public-payer footprint and the provider’s public-revenue exposure is concentrated in Medicare. The lack of Medicaid activity (no Medicaid billing on file) reduces public-payer diversification and makes Medicare reimbursement trends particularly material to the business.

Competitive standing is nationally prominent for several pathology services: 88341 ranks #6 of 10274 providers nationally and is described as a 100th percentile, "extreme outlier" far above typical national volume for this code, while 88342 ranks #22 of 11370 and is also a 100th percentile "extreme outlier." The provider also ranks #14 of 6757 on 88313 (100th percentile; "extreme outlier") and is notably above peers on 88305 (rank #373 of 14580; 97th percentile; "notably above typical national volume").

Operational throughput is high based on claim counts tied to top codes: 88341 has 13.9K claims, 88305 has 7.6K claims, 88342 has 5.4K claims, and 88313 has 6.7K claims, which together imply large-scale slide processing and interpretation capacity rather than occasional casework. These volumes are consistent with a centralized lab or a pathologist embedded in a high-volume surgical pathology workflow.

Revenue mix shows limited diversification beyond core pathology testing: aside from the dominant IHC and surgical pathology codes, the next notable Medicare code is 87506 (multiplex GI pathogen panel) at $61.1K (3.6%), which ranks #15 of 90 providers nationally and is characterized as an 84th percentile, "typical, unremarkable volume." This suggests molecular infectious-disease testing exists but is not a major revenue driver relative to pathology services.

Concentration risk is meaningful given top-code dominance: with 73.2% of Medicare revenue coming from the top three codes, reimbursement or utilization shifts affecting IHC (88341/88342) or surgical pathology (88305) could materially impact overall Medicare revenue. Monitoring changes in coding, reimbursement policies for antibody staining and surgical pathology levels, or referral patterns would be important for payers and network planners.

The provider has long tenure in the NPI file, enumerated on 2006-10-13 (~20 years), indicating an established billing history and sustained presence in Medicare over time; combined with the high national ranks on multiple codes, this tenure supports the interpretation of an established, high-throughput pathology practice rather than a new or transient entrant.
