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

Why is the Medicaid comparison limited to Florida 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. Florida (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

This provider is effectively a Medicare-only biller at scale: lifetime Medicare revenue is $7.1M while there is no Medicaid billing on file (none). The absence of any Medicaid activity means payer-mix analysis should treat this practice as functionally single-payer (Medicare) for the period on file.

Revenue is extremely concentrated in a single code: Q4205 accounts for $6.9M and 97.9% of this provider's total Medicare revenue, and the precomputed top-3 share is 98.8% of Medicare revenue. That concentration indicates the practice’s economics are driven almost entirely by membrane graft/wrap billing rather than a broad portfolio of evaluation-and-management or chronic-care codes.

Q4205 performance versus peers shows national prominence for that niche: the provider ranks #4 of 63 nationally (95th percentile) for Q4205 and is described as notably above typical national volume for this code. This ranking and dollar volume suggest the provider is a major national participant in membrane graft or membrane wrap billing, not a marginal supplier within that specific code set.

Other Medicare lines are present but represent only a sliver of revenue. For example, 99348 generated $35.6K (809 claims, 0.5% of Medicare revenue) and ranks #295 of 11547 nationally (97th percentile; notably above typical national volume), while 99442 produced $28.5K (475 claims, 0.4% of Medicare revenue) and ranks #178 of 21242 nationally (99th percentile; extreme outlier, far above typical national volume). These secondary high-percentile ranks indicate unusually high utilization in a few non-graft services even though they contribute little to total dollars.

The provider’s code mix suggests a hybrid operating model: dominant membrane graft or graft-supply billing (Q4205, 15271/15272 present) combined with home-based E/M and supervision services (99348, 99349, G0180, G0181) and some remote-monitoring codes (99454, 99457, 99458). This pattern is consistent with a practice that bills for both product/procedure-based wound-care services and home- or remote-focused patient management, but the financial heft is overwhelmingly on the membrane graft code.

Several codes are characterized as typical or unremarkable in volume despite appearing in the top entries, underscoring the extreme skew of this profile: 15271 is $24.4K (230 claims, 0.3% of Medicare revenue) and ranks #82 of 1157 (93th percentile; typical, unremarkable volume), while G0181 is $7.8K (120 claims, 0.1% of Medicare revenue) and ranks #485 of 1990 (75th percentile; typical, unremarkable volume). These entries illustrate that many codes in the top-25 list are not unusually large drivers of revenue compared with national peers.

From a competitive-risk perspective, the provider’s business is highly exposed to reimbursement or utilization changes for Q4205: with $6.9M tied to one add-on membrane graft code representing 97.9% of Medicare revenue and a precomputed top-3 share of 98.8%, any policy, pricing, or clinical-guideline shift affecting that code would materially impact total revenue. Analysts valuing stability should treat this concentration as a single-point-of-failure risk even though the provider is a major national biller for that specific code.

The provider has long tenure in Medicare billing, with the NPI enumerated on 2005-06-13 (~21 years ago). That multi-decade enrollment supports a sustained operating presence in the market, which helps explain the accumulation of $7.1M in Medicare revenue and the development of a concentrated specialty billing pattern over time.
