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’s service mix is strongly CT‑centric: the top revenue drivers are CT head (70450), CT abdomen and pelvis with contrast (74177), and CT abdomen and pelvis without contrast (74176), supplemented by CTA chest (71275) and routine chest x‑ray (71045). The presence of ultrasound (76705, 76770) and a handful of MRI codes (70551, 70553) indicates a broad diagnostic imaging footprint, but CT studies dominate both volume and revenue.

Revenue concentration is meaningful: the precomputed top 3 Medicare codes account for 39.5% of this provider’s total Medicare revenue, with 70450 at 14.7%, 74177 at 13.5%, and 74176 at 11.3%. This concentration signals operational dependence on a small set of CT procedures for a large share of Medicare income.

Payer mix is effectively single‑payer: reported lifetime Medicare revenue is $104K while there is no Medicaid billing on file, so the provider’s public‑payer exposure is concentrated in Medicare with no Medicaid revenue contribution. This limits Medicaid‑related risk but creates sensitivity to Medicare policy or utilization changes.

Competitive standing for core CT services is above typical but not dominant: 70450 and 74176 both rank in the 90th percentile nationally (70450: #2161 of 21092; 74176: #2165 of 22168; typical, unremarkable volume for these codes), and 74177 sits at the 76th percentile (#5573 of 23621; typical, unremarkable volume for this code). These rankings suggest the provider is a modestly higher‑volume participant in common CT exams relative to national peers rather than a market leader.

Operational throughput is skewed toward high‑count, low‑payment studies: 71045 shows 1.3K claims generating $9.4K (9.4% of Medicare revenue) and ranks #1768 of 25249 (93th percentile; typical, unremarkable volume for this code), indicating a sizable share of visits are plain chest radiographs that drive clinical throughput more than revenue. This pattern is consistent with an imaging practice handling many routine exams alongside higher‑reimbursement CTs.

Modality variability across codes highlights specialization: contrast vascular studies and CT angiography such as 71275 rank highly (71275: #1616 of 19107, 91th percentile; typical, unremarkable volume for this code) while several MRI codes have lower relative volume (70551: 41th percentile, #7787 of 13508; 70553: 16th percentile, #9294 of 11271; typical, unremarkable volume for these codes). That suggests the provider’s competitive strength is concentrated in CT and CTA services rather than in MRI.

Tenure and experience are established: the NPI was enumerated 2007-01-12 (~19 years ago), indicating long‑standing Medicare participation that likely supports stable referral relationships and operational continuity. This extended enumeration aligns with the mix of routine and advanced imaging services reported.

Statistical signals are mixed across lesser codes: some CPTs like 0042T and 71250 sit near mid‑range percentiles (0042T: 50th percentile, #512 of 1084; 71250: 59th percentile, #8752 of 21854; typical, unremarkable volume for these codes), while others such as 72148 and 70553 are in lower percentiles (72148: 16th percentile, #12331 of 14990; typical, unremarkable volume for this code). Overall, the profile shows pockets of above‑average CT volume alongside several lower‑volume MRI and specialty studies, reinforcing a CT‑focused clinical and revenue footprint.
