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

Why is the Medicaid comparison limited to South Carolina 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. South Carolina (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.

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

Key Findings

This provider is effectively single‑payer Medicaid in scope: Medicare revenue is none (no Medicare billing on file) while total Medicaid revenue is $31.2M, indicating the organization’s billed activity and financial footprint are concentrated in Medicaid payment streams. The absence of Medicare billing suggests the lab’s services are primarily contracted or reimbursed through state Medicaid arrangements rather than the Medicare program.

Revenue is extremely concentrated in a narrow set of services: the top 3 Medicaid codes account for 98.4% of the provider’s total Medicaid revenue, with S3870 alone representing $26.4M (84.6% of Medicaid revenue), 81229 representing $3.9M (12.6%), and 81479 contributing $370.2K (1.2%). This concentration implies the center’s business model and revenue are driven almost entirely by a few high‑value genetic testing procedures.

The code mix identifies the operation as a specialized clinical genetic testing laboratory: S3870 and 81229 are both comparative genomic hybridization (CGH)/chromosomal microarray procedures aimed at developmental delay, autism spectrum disorder, and intellectual disability, and 81479 captures other molecular pathology procedures without specific codes. The dominance of high‑complexity molecular and microarray testing (high average paid/claim for S3870 at $5092 and large claim volumes) is consistent with a lab focused on diagnostic genomic services rather than routine clinical chemistry or anatomic pathology.

S3870 is a state‑level outlier in terms of provider count and revenue source: it ranks #1 of 1 providers in‑state (0th percentile; no state peer volume comparison available) and accounts for $26.4M or 84.6% of this lab’s Medicaid revenue. That combination of being the sole in‑state reporter for S3870 and the code’s dominant revenue share indicates the lab is the primary in‑state source for large‑scale CGH microarray testing, though peer volume benchmarks are unavailable for direct comparison.

By contrast, 81229 shows the lab participates among multiple in‑state providers rather than being an isolated outlier: 81229 ranks #1 of 3 providers in‑state (100th percentile) and is described as typical, unremarkable volume for this code while contributing $3.9M (12.6% of Medicaid revenue). This pattern suggests the provider competes in commonly offered molecular testing services even as it dominates the single‑reported S3870 service.

Average paid and claim volume details underscore operational scale in a few services: S3870 has 5.2K claims at $5092 avg paid/claim and 81229 has 3.8K claims at $1037 avg paid/claim, indicating both high utilization and relatively high reimbursement per case for the primary tests. Those per‑claim averages and claim counts support the inference of a high‑throughput genetic testing operation handling many complex assays.

The lab maintains a broader, lower‑revenue cytogenetics and molecular test portfolio beyond its top two codes: codes such as 81243 ($230.5K, 0.7%), 88230 ($114K, 0.4%), 88261 ($73K, 0.2%), and others each contribute small shares of revenue, reflecting ancillary services like fragile X testing, lymphocyte culture, and chromosome analysis that complement the lab’s core microarray offerings. These smaller lines likely represent supplemental diagnostics and interpretations rather than primary revenue drivers.

The provider is long‑standing in the national registry, with NPI enumerated 2005‑11‑03 (~21 years ago), indicating sustained operation and experience in the genetic testing market. Combined with the concentrated, high‑value Medicaid revenue mix, this tenure suggests an established, specialized lab that has focused its service line around genomic microarray and molecular pathology testing over many years.
