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

Why is the Medicaid comparison limited to Unspecified Location 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. Unspecified Location (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.

Nusrat Perveen (NPI 1306595327)

Nusrat Perveen is a anatomic pathology & clinical pathology physician provider located in Oakville, Unspecified Location. This profile covers 10 Medicare and 0 Medicaid CPT/HCPCS procedure codes, with claims volume, average reimbursement, and total revenue by code, benchmarked against other providers billing the same services. Note: "XX" is a placeholder CMS uses when a provider's practice-location state wasn't reported — not a traditional US state; claims coded under it are grouped and benchmarked here the same way a traditional state would be.

The provider appears to operate as a pathology-focused practice: the top codes are surgical pathology examinations and ancillary immunohistochemistry stains (88305, 88307, 88341), which together reflect routine tissue accessioning, microscopic review, and targeted antibody staining rather than front-line clinical office visits. This code mix indicates primary activity is laboratory-based diagnostic pathology services.

Revenue is highly concentrated in a small set of pathology codes: the precomputed top three Medicare codes (88305, 88307, 88341) account for 77.5% of this provider's total Medicare revenue, with 88305 contributing $9.3K (48.2%), 88307 $3.7K (19.3%), and 88341 $1.9K (10.0%). This concentration implies most Medicare billing value is captured in a few surgical pathology/intact immunostain services.

Scale of operations is very small on a lifetime basis: total Medicare revenue is $19.4K while Medicaid revenue is none, so the provider is effectively single-payer with Medicare representing the entire recorded public-payer revenue stream. The absence of Medicaid billing means there is minimal diversification across public payers.

Competitive standing on Medicare is modest rather than dominant: 88305 ranks #8633 of 14580 providers nationally (41th percentile; typical, unremarkable volume), 88307 ranks #5292 of 8511 (37th percentile; typical, unremarkable volume), and 88341 ranks #8312 of 10274 (19th percentile; typical, unremarkable volume). Those percentiles and rank positions indicate the provider is a routine-volume participant for these codes nationally and not a major or regional leader.

There is evidence of occasional higher-complexity pathology work but at low volume: 88309 (level VI exam) accounts for $1.5K (8.0%) and 88331 (intraoperative consultation) accounts for $705 (3.7%) of Medicare revenue, indicating the practice can perform more complex surgical pathology reviews and frozen-section consults but these services are minority contributors to revenue. The code mix suggests most demand is for standard surgical pathology reviews with intermittent higher-intensity cases.

Claim-level patterns point to throughput-driven, lower-paid work: 88305 shows 357 claims at a $26 avg paid/claim for $9.3K revenue, while 88341 shows 92 claims at $21 avg paid/claim and 88307 shows 62 claims at $60 avg paid/claim. These figures are consistent with a workflow that processes many routine pathology specimens where cumulative revenue accrues from volume rather than high per-claim reimbursements.

Provider tenure is relatively recent: the NPI was enumerated on 2022-03-18 (~4 years ago), which may help explain the limited lifetime Medicare revenue to date and suggests benchmarking growth in future reporting periods could be informative. A short enrollment window increases the likelihood that historical revenue totals understate long-term capacity if the practice is still scaling.

The complete absence of Medicaid billing on file ("none below") is notable for payer-mix assessment: either the provider is not enrolled or not billing Medicaid, or Medicaid work is routed outside the tracked channels. This lack of Medicaid activity concentrates exposure to Medicare reimbursement dynamics and limits visibility into this provider's role in serving lower-income or Medicaid-covered populations.
