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.

The Medicare and Medicaid tables are both single current snapshots, not refreshed on a recurring schedule yet.

Key Findings

This provider is a Nevada-based Ophthalmology Physician in Las Vegas with $2.7M in lifetime Medicare revenue and no Medicaid billing on file, making Medicare the sole public payer exposure reported. The NPI was enumerated 2006-05-20 (~20 years ago), indicating a long-tenured practice likely with an established referral network.

Revenue is highly concentrated in a small set of injectable biologics and unclassified biologic billing: J0178 (1.9K claims, $697 avg paid/claim, $1.3M revenue, 49.8% of Medicare revenue), J3590 (195 claims, $2129 avg paid/claim, $415.2K revenue, 15.4%), and J0179 (750 claims, $248 avg paid/claim, $186K revenue, 6.9%). The precomputed top-3 share of 72.1% underscores dependence on high-cost drug administration as the primary revenue driver rather than a broad mix of office procedures.

The service-line mix—dominated by intravitreal injections (J0178, J0179, J2781) and intravitreal implants (J7312) along with high volumes of retinal imaging (92134)—is consistent with a retina-focused, ambulatory injection practice that prioritizes medical retina therapies over high volumes of intraocular surgery. Specific codes supporting this include J7312 (1K claims, $156 avg paid/claim, $161.1K revenue) and 92134 (2.2K claims, $30 avg paid/claim, $64.8K revenue).

Competitive standing by code shows a mixed profile: for J0178 the provider ranks #569 of 3204 (82th percentile; typical, unremarkable volume) indicating modest national presence for aflibercept injections, while J0179 ranks #10 of 64 (86th percentile; typical) showing relatively high placement among a small set of brolucizumab billers. J3590 ranks #189 of 631 (70th percentile; typical), so the provider is generally a solid but not dominant national player for the top biologic codes.

There are notable statistical outliers in the practice pattern that reflect high visit and procedure throughput: 99213 is an extreme outlier (1.8K claims, $63 avg paid/claim, $111.9K revenue; 100th percentile), J7312 is an extreme outlier (rank #3 of 492; 100th percentile), and 92134 is notably above typical (2.2K claims; 97th percentile). These outliers point to sustained high-volume office-based care and frequent imaging consistent with ongoing intravitreal treatment and close follow-up.

Surgical retinal procedures are present but limited: 67042 shows 15 claims ($915 avg paid/claim, $13.7K revenue) and 67036 shows 12 claims ($670 avg paid/claim, $8K revenue), with ranks indicating lower-than-midline national surgical volume. This suggests the practice performs occasional vitreoretinal surgery but primarily operates as a non-surgical, injection- and clinic-focused practice.

Payer-mix risk is concentrated: with $2.7M in Medicare revenue and no Medicaid billing on file, the provider is effectively single-payer (Medicare) in the public sector. Given that biologic drug administration comprises the lion’s share of revenue (top 3 codes = 72.1%), changes in Medicare reimbursement for injectable drugs or administration fees would disproportionately impact this provider's revenue.

Operational implications for contracting and referral strategy are clear: the high volumes of injection codes and diagnostic imaging (e.g., J0178, J0179, J7312, 92134) combined with long tenure (NPI since 2006-05-20 ~20 years) suggest an established retinal specialty practice that could be a priority target for payers and specialty vendors focused on intravitreal therapy management, prior authorization workflows, and drug-cost interventions.
