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

Why is the Medicaid comparison limited to Washington 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. Washington (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.

Key Findings

COLLIN PERRI is effectively a single-payer Medicare billing provider: lifetime Medicare revenue is $3.8M and there is no Medicaid billing on file, indicating this profile reflects Medicare-dominated activity rather than a mixed payer practice. This concentration means any analysis of service mix and volume should focus on Medicare claims rather than state Medicaid comparisons.

Revenue concentration is extreme: the precomputed top-3 Medicare codes account for 99.7% of this provider's total Medicare revenue, and a single code, Q4205, alone accounts for $3.7M (99.2% of Medicare revenue). This level of concentration indicates the provider’s financial activity is overwhelmingly driven by procedures associated with Q4205 rather than a diversified set of E/M or ancillary services.

Service-line implication: the dominant use of Q4205 (Membrane graft or membrane wrap, per square centimeter; add-on) together with smaller volumes of skin substitute codes 15275 and 15271 suggests the provider primarily performs or bills for advanced wound or grafting procedures, likely focused on placement of biological or synthetic membranes as part of wound coverage. The presence of lower-volume ED E/M and debridement codes indicates occasional emergency or wound-care encounters, but these are minor contributors to revenue.

Competitive standing for the primary code Q4205 is solid but not exclusive: the provider ranks #11 of 63 nationally for Q4205 and sits in the 84th percentile, which indicates above-typical national activity for this code but not dominance of the national market. In contrast, secondary codes show mixed positioning: 15275 is at the 87th percentile (rank #109 of 888), indicating higher-than-typical use among peers for that skin substitute application, while 15271 is near the national median (53th percentile, rank #534 of 1157).

Operational scale and utilization details: Q4205 was billed in 3.3K claims at an average paid/claim of $1146, which drives most of the provider’s Medicare receipts; by comparison other commonly billed codes such as 99284 and 99285 (ED E/M) have very low revenue shares ($5.1K and $1.7K respectively), underscoring that routine E/M visits are not a primary revenue stream for this provider. The code mix points to a procedure-focused practice where add-on graft billing is the core activity.

Tenure and professional classification: the provider’s NPI was enumerated on 2021-03-15 (~5 years ago), so this billing profile represents a relatively recent practice history rather than decades-long Medicare activity. Combined with concentrated coding, this suggests a relatively new but procedure-focused Medicare billing pattern has developed since enumeration.

Statistical standing across non-primary codes is generally typical to below-typical: several E/M and wound-care codes (99284, 99285, 97597, 99212, 99283) are described as typical or unremarkable volumes with percentiles ranging from low to mid ranks nationally, indicating no notable outlier behavior outside the dominant Q4205 and selected skin substitute codes. This supports the interpretation that the provider’s specialization is narrowly concentrated rather than broadly atypical across many code families.
