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

Why is the Medicaid comparison limited to Ohio 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. Ohio (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

This provider’s Medicare footprint is the sole payer presence of note: total Medicare revenue is $2M and Medicaid billing is none on file, making the practice effectively Medicare‑centric. The NPI was enumerated 2008-01-11 (~18 years ago), indicating an established practice tenure that likely supports sustained referral and treatment patterns.

Revenue is highly concentrated in a small set of drugs and procedures: the precomputed top three Medicare codes account for 87.3% of this provider’s Medicare revenue. Those top contributors are J0178 ($1.2M, 59.7% of Medicare revenue), J2777 ($400.2K, 20.0%), and 67028 ($151.7K, 7.6%), showing dependence on intravitreal drug therapy and related injection services.

The code mix matches a retina-focused, procedure-driven practice: dominant use of intravitreal drug codes J0178 (1.7K claims) and J2777 (13.8K claims) together with the injection procedure 67028 (1.7K claims) points to a high-volume anti-VEGF/faricimab injection service line. Significant retinal imaging (92134, 2.3K claims) accompanies those treatment codes, consistent with frequent diagnostic monitoring in retinal disease management.

On competitive standing for the top drug and injection codes, the provider is a solid but not dominant national participant: J0178 ranks #667 of 3204 providers nationally (79th percentile; typical, unremarkable volume for this code) and J2777 ranks #759 of 2039 providers nationally (63th percentile; typical, unremarkable volume for this code). The injection procedure 67028 ranks #594 of 4255 providers nationally (86th percentile; typical, unremarkable volume for this code), indicating somewhat above-average procedural volume but still within the typical range nationally.

Certain diagnostic and visit codes are statistical outliers relative to peers. 92134 (retinal imaging) ranks #802 of 26868 providers nationally (97th percentile; extreme outlier), signaling exceptionally high imaging utilization for this specialty, and J3590 (unclassified biologics) ranks #41 of 631 providers nationally (94th percentile; notably above typical national volume), suggesting elevated use of miscellaneous biologic products in addition to named agents.

High‑complexity new patient E/M is unusually frequent: 99204 (218 claims, $24.6K revenue) ranks #3740 of 227068 providers nationally (98th percentile; extreme outlier). Although 99204 represents a small share of total Medicare revenue (1.2%), its elevated percentile rank indicates the practice receives a disproportionate number of high‑complexity new patient evaluations compared with national ophthalmology peers.

Surgical retina activity is limited: vitrectomy and related surgery codes 67042, 67041, and 67036 each have very low claim counts (13, 12, and 12 claims respectively) with modest revenue shares (0.6%, 0.5%, 0.4%) and low national ranks (13th, 8th, and 7th percentiles respectively). This pattern suggests the provider’s operation emphasizes office‑based injections and diagnostics over higher-volume surgical interventions.

Payer and contracting implications follow directly from the data: with $2M in Medicare revenue, no Medicaid billing on file, and a revenue base concentrated (87.3%) in a few injection and diagnostic codes, the provider’s value to payers will be driven by access to intravitreal drug administration and retinal imaging capacity. For network or utilization management discussions, focus on drug utilization, injection throughput, and imaging frequency rather than on surgical volume or Medicaid coverage expansion.
