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

Why is the Medicaid comparison limited to Nevada 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. Nevada (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

The provider’s Medicare business is overwhelmingly driven by intravitreal anti-VEGF therapy: J0178 (Injection, aflibercept) accounts for 1.4K claims, $681 avg paid/claim, $961.6K revenue (80.1% of this provider's total Medicare revenue) and is the dominant single-code revenue source within a $1.2M Medicare book. Supplemental procedure and diagnostic codes that support medical retina care — notably 67028 (715 claims, $92 avg paid/claim, $65.8K revenue) and 92134 (1.3K claims, $29 avg paid/claim, $37.3K revenue) — align with an injection-plus-imaging service line model focused on retinal disease management.

Revenue concentration is very high: the precomputed top 3 Medicare codes account for 91.3% of this provider’s Medicare revenue, signaling material dependency on a small set of procedure/drug codes. For payers and risk managers, this indicates that changes in reimbursement, utilization management, or block-bustering of aflibercept supply or coding rules for these specific codes would disproportionately affect the provider’s topline.

This provider is effectively single-payer at present: total Medicare revenue is $1.2M while Medicaid revenue is none, so there is no Medicaid billing on file. That asymmetry suggests contracting, network access, and population health engagement efforts will need to focus on Medicare relationships rather than Medicaid arrangements for this NPI.

Competitive standing is mixed across codes: J0178 ranks #888 of 3204 providers nationally (72th percentile; typical, unremarkable volume for this code), indicating solid but not market-leading anti-VEGF volume. By contrast, the E/M code 99213 shows unusually high office-visit volume with 1K claims, $66 avg paid/claim, $69.2K revenue (5.8% of this provider's total Medicare revenue) and ranks #5725 of 457151 providers nationally (99th percentile; extreme outlier), implying this practice logs far more established-patient visits than most peers.

Clinical operations appear imaging- and procedure-integrated: 92134 (retinal imaging) at 1.3K claims and $37.3K revenue ranks #1768 of 26868 providers nationally (93th percentile; notably above typical national volume for this code), supporting an on-site diagnostic workflow that complements intravitreal therapy. The presence of both high imaging (92134) and high procedure counts (J0178, 67028) points to a vertically aligned retina practice that performs diagnosis, monitoring, and drug delivery in-clinic.

Several codes signal above-typical complexity or intake intensity: 99205 (new patient, high complexity) shows 103 claims, $158 avg paid/claim, $16.3K revenue (1.4% of this provider's total Medicare revenue) and ranks #2916 of 66257 providers nationally (95th percentile; notably above typical national volume). This suggests the provider receives a relatively high share of complex new referrals or documents higher-complexity new visits compared with peers.

Other drug and supply codes are comparatively small contributors and not market-leading: J3490 (Unclassified drugs) produced 19 claims, $2064 avg paid/claim, $39.2K revenue (3.3% of Medicare revenue) and ranks #2642 of 2838 providers nationally (6th percentile; typical, unremarkable volume for this code), while J9035 (bevacizumab) contributes $3.5K (0.3%) and ranks in the lower national percentiles. These smaller, lower-ranked revenue sources indicate limited diversification outside the primary aflibercept-driven service line.

The NPI tenure indicates an established presence in the market: the provider was enumerated (registered) 2006-06-07 (~20 years ago), which supports interpretation of the utilization profile as the output of a mature practice rather than a recently opened clinic. For payer contracting and capacity planning, an established, concentrated Medicare revenue stream combined with long tenure suggests predictable, entrenched patterns of care that could be sensitive to targeted policy or reimbursement changes affecting the top codes.
