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

Why is the Medicaid comparison limited to New Jersey 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. New Jersey (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 revenue is highly concentrated in intravitreal biologic therapy and related services: J0178 generated $1.1M (41.3% of Medicare revenue), J2777 generated $428K (16.2%), and J3590 generated $252.2K (9.5%), and the precomputed top-three codes account for 67.0% of total Medicare revenue. Together these code-level concentrations indicate the practice’s core service line is high-volume retinal injections and administration of ophthalmic biologics alongside routine ophthalmology care.

The practice is effectively single-payer at the claims level: lifetime Medicare revenue is $2.6M while Medicaid revenue is none, so all recorded public-payer activity is Medicare-driven. That payer mix implies product mix, scheduling, and revenue risk are tightly tied to Medicare reimbursement and utilization patterns rather than to dual Medicaid/Medicare business.

Despite large dollar volumes in anti-VEGF therapy, the provider is not a national outlier for the top injectable codes: J0178 ranks #761 of 3204 providers nationally (76th percentile; typical, unremarkable volume), J2777 ranks #726 of 2039 (64th percentile; typical, unremarkable volume), and J3590 ranks #278 of 631 (56th percentile; typical, unremarkable volume). In other words, revenue concentration stems from high absolute dollars rather than from unusually high national market share for these specific drug codes.

Clinical visit and diagnostic volumes show pockets of exceptional activity: 92014 produced 1.9K claims and $202.2K revenue (7.6%) and ranks #304 of 35415 providers nationally (99th percentile; extreme outlier), indicating an unusually high volume of comprehensive established-patient ophthalmology visits. Complementary retinal diagnostics are also above typical national volume — 92134 (1.9K claims, $69K; 96th percentile) and 92202 (1.2K claims, $15.2K; 95th percentile) — which together point to a busy clinic workflow that combines high visit throughput with imaging-heavy retinal management.

The provider bills a mix of classified and unclassified drug codes with meaningful per-claim payment levels: J3590 has an average paid/claim of $2357 and J3490 has an average paid/claim of $1949, generating $252.2K and $91.6K respectively. Use of unclassified drug codes at these dollar levels suggests the practice administers higher-cost biologic or non-standard drug products in addition to labeled anti-VEGF agents, which has implications for inventory, acquisition, and payer adjudication processes.

Procedural ophthalmology activity beyond injections is material but not dominant: 67028 shows 1.4K claims for $147.4K revenue (5.6%) and ranks #912 of 4255 providers (79th percentile; typical, unremarkable volume), while focal procedures such as 67228 and ultrasound 76512 appear at much smaller revenue shares. This mix indicates the practice pairs intravitreal drug delivery with some office-based procedural work rather than functioning primarily as a surgical retina center.

Coding and service-profile volatility should be monitored because a large share of revenue comes from a small set of drugs and codes (top 3 = 67.0%), and several high-dollar drug lines are reported under unclassified codes (J3590, J3490). Payor contract negotiations, drug formulary changes, or shifts in clinical guidelines for retinal biologics could therefore materially affect this provider’s revenue trajectory.

The provider has an established Medicare presence with an NPI enumerated 2015-07-13 (~11 years ago), supporting a stable operating history tied to ophthalmology specialty services and repeated retinal care encounters. Combined with $2.6M in lifetime Medicare revenue and the high volume of established-patient visits, this tenure and volume profile is consistent with an established retinal/imaging-focused ophthalmology practice rather than a newly formed or episodic billing entity.
