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

Why is the Medicaid comparison limited to Maryland 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. Maryland (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 billing footprint is effectively single‑payer: lifetime Medicare revenue is $2.7M and there is no Medicaid billing on file, so Medicare dominates the practice’s public‑payer exposure. The NPI was enumerated on 2015-04-30 (~11 years ago), indicating roughly a decade of Medicare billing history to evaluate trends against peers.

Revenue is highly concentrated in a small set of injection-related codes: J0178 accounts for 54.3% of Medicare revenue, J2777 for 28.9%, and the intravitreal injection procedure 67028 for 5.2%; the precomputed top‑3 share totals 88.4% of Medicare revenue. This concentration signals that anti‑VEGF and related intravitreal therapies are the primary revenue drivers rather than clinic‑based office visits or surgical retina services.

The mix of J0178 (aflibercept), J2777 (faricimab), and 67028 (intravitreal injection) aligns with a retina‑focused, procedure‑centric practice model emphasizing regular anti‑VEGF treatment and repeat injections. Operationally, that pattern supports a high‑throughput injection workflow and frequent treatment/monitoring cycles typical for wet AMD, diabetic macular edema, and other retinal vascular diseases.

On competitive standing for the top drug codes, the provider is a modest national participant rather than a market leader: J0178 ranks #471 of 3204 (85th percentile; typical, unremarkable volume) and J2777 ranks #345 of 2039 (83th percentile; typical, unremarkable volume). These placements indicate above‑median activity but not dominance in national anti‑VEGF administration.

Imaging and diagnostic monitoring are unusually prominent: 92134 appears with 2.4K claims and $69.5K revenue and ranks #722 of 26868 (97th percentile; extreme outlier, far above typical national volume). That extreme outlier status for retinal imaging suggests an intensive follow‑up and monitoring protocol that complements the high injection volume and may reflect subspecialty clinic workflows or imaging‑heavy care pathways.

New patient evaluations are also notably elevated: 99204 has 230 claims and $26.5K revenue and ranks #3211 of 227068 (99th percentile; extreme outlier, far above typical national volume). This pattern points to a higher-than‑typical inflow of new consults or referrals, which could support sustained procedural caseload and justify investment in clinic capacity.

Routine ophthalmology E/M codes are present but represent a smaller share of revenue: 92014 (651 claims, $53.4K) ranks #3726 of 35415 (89th percentile; typical, unremarkable volume) and 92012 (630 claims, $41K) ranks #1217 of 17177 (93th percentile; typical, unremarkable volume). These figures indicate the practice still provides office‑based continuity care, but those services are secondary to injection and imaging activity.

The absence of any Medicaid billing on file means this provider’s public‑payer mix lacks Medicaid exposure, which has implications for network participation, patient access for Medicaid beneficiaries, and payer negotiation strategies. Analysts should treat the provider as effectively Medicare‑dependent when modeling payer mix, utilization, and potential market reach in the state.
