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

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

This provider’s billing footprint is concentrated in Medicare with total Medicare revenue of $238.7K and no Medicaid billing on file, making the practice effectively single‑payer from a public program perspective. The lack of Medicaid claims limits exposure to state program volume and means comparisons and competitive positioning should be assessed primarily against Medicare peers.

Revenue is highly concentrated in a few procedure lines: the precomputed top three Medicare codes (90960, 99232, 90935) account for 59.6% of this provider’s total Medicare revenue. The single largest code is 90960 ($82.5K, 34.5% of Medicare revenue), followed by 99232 ($33K, 13.8%) and 90935 ($26.9K, 11.3%), indicating that a small set of services drives the majority of billing.

The mix of billed codes points to a nephrology practice centered on ESRD and dialysis management with substantial hospital-based care. Codes 90960 and 90961 are monthly ESRD management visits and 90935/90937 are hemodialysis procedure codes, while 99223/99232/99233 and 99291 reflect significant inpatient and critical care activity, suggesting the provider operates across dialysis and acute hospital settings.

One striking competitive signal is the 90935 hemodialysis volume: the provider ranks #33 of 6114 nationally (99th percentile) and is labeled an "extreme outlier, far above typical national volume for this code." This places the provider among the highest-volume national billers for hemodialysis procedures and indicates a disproportionately large dialysis procedure throughput relative to peers.

Other high-revenue codes show solid but not dominant national standing: 90960 ranks #1013 of 6549 (84th percentile; typical, unremarkable volume), 99232 ranks #13482 of 177383 (92th percentile; typical, unremarkable volume), and 99223 ranks #9908 of 139583 (93th percentile; typical, unremarkable volume). These positions suggest consistent participation in ESRD management and inpatient E/M care without consistent top-decile dominance across all major codes.

Critical care billing is a meaningful part of the mix: 99291 contributes $25.5K (10.7% of Medicare revenue) and ranks #8007 of 71290 (89th percentile; typical, unremarkable volume). The presence of critical care revenue alongside dialysis codes indicates the provider treats seriously ill nephrology patients in acute settings as well as managing chronic dialysis care.

From a revenue risk and operational perspective, heavy reliance on dialysis/ESRD codes (with the top three codes representing 59.6% of Medicare revenue) makes the practice sensitive to changes in dialysis patient volume, ESRD contract arrangements, or reimbursement for those specific CPTs. Combined with no Medicaid revenue to diversify payer mix, financial performance is closely tied to Medicare dialysis and related inpatient billing patterns.

The provider’s NPI was enumerated on 2009-02-26 (~17 years ago), indicating a long-established billing history under this identifier. That tenure supports the interpretation that observed code-mix patterns (ESRD management, high dialysis procedure volume, and inpatient/critical care work) are likely entrenched elements of the practice rather than a short-term anomaly.
