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

Why is the Medicaid comparison limited to New Jersey 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. New Jersey (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.

The provider’s Medicare revenue is overwhelmingly driven by K1034: 465.6K claims, $12 avg paid/claim, $5.6M revenue (96.8% of this provider's total Medicare revenue). This single code accounts for nearly the entirety of billed Medicare services and indicates the operation is primarily provisioning COVID-19 nonprescription self-administered tests rather than generating most revenue from traditional office-based E/M visits or chronic care management.

Precomputed concentration shows the top 3 Medicare codes account for 97.6% of total Medicare revenue, signaling extreme revenue concentration in a very small code set. That level of concentration suggests the practice’s financial performance on Medicare is highly sensitive to utilization or reimbursement changes tied to those top codes.

Medicare is effectively the sole public payer for this provider: lifetime Medicare revenue is $5.7M while there is no Medicaid billing on file. The absence of any Medicaid activity indicates a single-payer dependency on Medicare for public-program revenue rather than a balanced Medicare/Medicaid payer mix.

Competitive standing for K1034 is extraordinary: the provider ranks #83 of 30143 providers nationally (100th percentile; extreme outlier, far above typical national volume for this code). By contrast, routine E/M codes are modest contributors — for example, 99214 shows 219 claims, $108 avg paid/claim, $23.7K revenue (0.4% of total) and ranks #139691 of 479517 providers nationally (71th percentile; typical, unremarkable volume) — indicating national dominance in the COVID-test code but ordinary participation in office visit care.

The code mix beyond K1034 shows a substantive ancillary services footprint: notable volumes in procedures such as 20553 (276 claims, $54 avg paid/claim, $14.9K revenue; ranks #133 of 4042 nationally, 97th percentile; notably above typical) and 76942 (262 claims, $52 avg paid/claim, $13.6K revenue; ranks #172 of 13333 nationally, 99th percentile; notably above typical). These patterns point to service lines including trigger point injections, diagnostic ultrasonography guidance, and other procedure-based interventions in addition to test provisioning.

Several electrodiagnostic and rehabilitation-related codes appear regularly but at much smaller revenue shares (examples: 95886 — 172 claims, $88 avg paid/claim, $15.1K revenue; 95913 — 31 claims, $255 avg paid/claim, $7.9K revenue). While each of these codes contributes only a small share of Medicare revenue, their presence suggests the provider offers multi-modal diagnostic and musculoskeletal/pain management services alongside testing.

Tenure and professional specialty support the profile: NPI enumerated 2007-03-19 (~19 years ago) and taxonomy is Internal Medicine Physician located in RIDGEWOOD, NJ. The long enumeration period indicates an established practice, but the current Medicare revenue profile is atypical for a general internal medicine practice because revenue is dominated by a single testing code.

From an operational and payer-risk perspective, reliance on K1034 (96.8% of Medicare revenue) and top-3 code concentration (97.6% of Medicare revenue) creates vulnerability to changes in Medicare policy or demand for COVID-19 nonprescription self-tests. Analysts and payers should flag this provider as highly specialized in COVID test provisioning at Medicare scale and monitor reimbursement policy and utilization trends for those specific codes.
