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

Why is the Medicaid comparison limited to South Carolina 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. South Carolina (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’s billing footprint is concentrated almost entirely in Medicare with Total Medicare revenue of $2.1M and Total Medicaid revenue reported as none, so the practice functions effectively as a Medicare-dependent operation with no Medicaid claims on file. The lack of Medicaid activity should be treated as a material characteristic of payer mix when modeling revenue sensitivity or network access in-state.

Revenue is highly concentrated in a small set of injectable retinal therapies: J2777 accounts for $964K (45.6% of Medicare revenue) and the precomputed top-3 codes together account for 83.0% of this provider’s total Medicare revenue. That concentration indicates the practice derives the bulk of its Medicare dollars from high-cost retinal drug administration rather than broad primary-care E/M or high-volume ancillary services.

The top-coded services show a clear retina specialty operational model: J2777 (faricimab), J0178 (aflibercept), and Q5128 (ranibizumab-eqrn biosimilar) dominate the revenue mix, which aligns with a clinic workflow built around repeated intravitreal injections and associated monitoring. Supporting codes such as 92134 (retinal imaging) and 67028 (isolated intravitreal injection procedure) appear in the top codes, reinforcing that clinical throughput is centered on injection visits and diagnostic imaging.

Competitive standing for the primary drug codes is generally in the "typical, unremarkable" range nationally despite large revenue shares. Specifically, J2777 ranks #247 of 2039 nationally (88th percentile; typical, unremarkable volume for this code), J0178 ranks #1437 of 3204 (55th percentile; typical, unremarkable volume for this code), and Q5128 ranks #155 of 373 (59th percentile; typical, unremarkable volume for this code), indicating the provider is not an outlier leader nationally on these product lines.

One notable outlier in diagnostics is 92134 (computerized retinal imaging), which has 1.9K claims, $57 paid/claim, and $57K revenue (2.7% of Medicare revenue) and ranks #1140 of 26868 providers nationally (96th percentile; notably above typical national volume for this code). This elevated imaging volume suggests substantial in‑office diagnostic throughput that likely supports frequent injection visits and follow-up management.

Although injections and imaging dominate, the provider also reports surgical/therapeutic retina activity at a smaller scale: 67028 shows 1.1K claims and $107.3K revenue (5.1% of Medicare revenue) and codes for vitrectomy/retinal repair such as 67041 and 67108 appear with modest counts and revenues. Those entries indicate the practice performs some procedural surgical work in addition to pharmacologic management, but surgery is a minority revenue stream compared with drug administration.

The provider’s NPI was enumerated 2013-03-27 (~13 years ago), which establishes a multi-year presence in the Medicare program; when combined with $2.1M total Medicare revenue, this tenure suggests a stable, established retina practice rather than a new entrant. Tenure should be considered when benchmarking referral patterns or projecting patient volume stability.

The heavy dependence on a few high-cost drug codes (top single code J2777 = $964K and top-3 = 83.0% of Medicare revenue) paired with no Medicaid revenue creates concentrated operational and payer risk: shifts in drug utilization, formulary coverage, or Medicare reimbursement for these specific J- and Q-codes could materially impact revenue. Analysts should monitor utilization mix between branded agents and biosimilars (for example J0178 versus Q5128) and watch for changes in claim counts for 92134 that support ongoing injection frequency.
