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

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

CHRISTOPHER KOTTRA reports Total Medicare revenue of $449K and has no Medicaid billing on file, so the provider’s public payment footprint is effectively single‑payer (Medicare) in the available data. This payer concentration means analyses of volume and revenue risk should be framed around Medicare flows rather than state Medicaid activity.

Revenue is highly concentrated in a narrow set of mammography/tomosynthesis codes: the precomputed top 3 Medicare codes (77067, 77063, 72197) account for 76.0% of this provider’s total Medicare revenue. The two dominant codes are 77067 (45.6% of Medicare revenue) and 77063 (25.7% of Medicare revenue), with 72197 contributing a further 4.7%.

The code mix indicates a focused breast‑imaging practice with very high throughput for screening and diagnostic mammography and tomosynthesis: 77067 shows 2.4K claims at $85 avg paid/claim and 77063 shows 2.4K claims at $48 avg paid/claim, and diagnostic/biopsy codes such as 19083 (57 claims, $281 avg paid/claim) and focused ultrasound 76642 (227 claims, $49 avg paid/claim) also appear in the top codes. These volumes and the specific CPTs imply operational workflows optimized for high‑volume breast screening and targeted image‑guided procedures rather than a general radiology mix.

For competitive standing on Medicare mammography the provider is an outlier nationally: 77067 ranks #161 of 15198 providers (99th percentile; extreme outlier) and 77063 ranks #146 of 14277 providers (99th percentile; extreme outlier), indicating a dominant national footprint for those screening/tomosynthesis services. Additional breast imaging codes reinforce that position: 77065 ranks in the 99th percentile (extreme outlier) and G0279 ranks in the 98th percentile (notably above typical national volume), showing consistently elevated activity across multiple breast‑imaging CPTs.

Despite the breast imaging dominance, other modality participation is modest. MRI pelvis 72197 (82 claims, $254 avg paid/claim) contributes 4.7% of Medicare revenue and ranks #992 of 4732 providers (79th percentile; typical, unremarkable volume), while multiple CT codes (for example 74177 and 70450) sit in lower national percentiles (around the 28–29th percentiles), indicating comparatively limited CT/advanced cross‑sectional work relative to the mammography business line.

The high claim counts for screening/tomosynthesis (2.4K claims each for 77067 and 77063) together with average paid/claim levels ($85 and $48 respectively) point to a high‑throughput, procedure‑driven revenue model where a small set of CPTs drives the majority of income. Operationally, this suggests scheduling, staffing, and capital (mammography/DBT) are likely concentrated on sustaining large volumes of routine breast screening and associated diagnostic follow‑ups.

The provider’s NPI was enumerated on 2005-09-26 (~21 years ago), indicating long tenure in the Medicare program; that longevity combined with the concentrated breast‑imaging volumes implies an established service line rather than a recent or transient billing pattern.
