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

This provider’s Medicare activity is highly concentrated in a narrow set of procedure add-ons: Q4158 and Q4205 together account for 90.3% of Medicare revenue and the precomputed top 3 codes represent 94.5% of total Medicare revenue. The mix of dominant codes — Q4158 (Kerecis omega3) and Q4205 (membrane graft/wrap) — indicates the practice is focused on advanced skin substitute and grafting products rather than general outpatient office care or routine E/M services.

Q4158 is the single largest revenue driver, generating $8.4M and representing 57.0% of the provider’s Medicare revenue; the provider ranks #1 of 36 nationally for this code and is described as an extreme outlier. This national leading position for Q4158 signals a specialized, high-volume use of this particular graft material relative to peers and suggests differentiated service capability or a specialized wound-care/surgical supply emphasis.

Q4205 contributes $4.9M (33.3% of Medicare revenue) and the provider ranks #7 of 63 nationally (90th percentile). While not as uniquely dominant as Q4158, this high placement for Q4205 reinforces that membrane grafting/wraps are a core service line and that the provider performs at substantially higher-than-typical national volumes for these skin-substitute products.

G0277 (hyperbaric oxygen therapy) accounts for $623.7K and 4.2% of Medicare revenue, with a #3 national rank and a 97th percentile standing described as notably above typical national volume. The presence of both high-volume skin substitute codes and elevated hyperbaric oxygen utilization suggests an integrated wound care and tissue-healing service line offering multiple advanced therapies for complex or non-healing wounds.

The provider shows negligible Medicaid activity — the record states no Medicaid billing on file — so payer mix is effectively single-payer Medicare for the dataset provided. With $14.7M in total Medicare revenue and no Medicaid revenue, this practice’s exposure and financial footprint in public payer data is concentrated entirely in Medicare and specific high-cost product codes.

Several other procedural and inpatient E/M codes (for example, 99233, 99232, 15271, and 99183) appear with notable ranks at or near extreme outlier percentiles, indicating unusually high volumes of related inpatient and adjunct wound-care services versus national peers. This pattern — high-volume add-on graft materials, hyperbaric therapy supervision codes, and inpatient E/M claims — is consistent with a practice that treats complex wound and reconstructive cases requiring both surgical grafting and supportive therapies.

The provider has a long tenure in the NPI registry, enumerated approximately 18 years ago (2008-04-16), which supports the possibility of an established referral base or institutional relationships feeding high volumes of the specialized services reflected in the billing mix. That tenure combined with concentrated service lines and national-ranking outlier positions suggests established operational scale in these therapies.

From a competitive standpoint, the combination of a #1 national rank for Q4158 and top-decile ranks for several other product and therapy codes positions this provider as a dominant national outlier for a small set of advanced wound-care/skincare substitute services, rather than a broad-spectrum plastic surgery practice. Payers and provider analysts should view this entity as a specialized, high-volume supplier of specific graft and wound-healing interventions within the Medicare population.
