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

Why is the Medicaid comparison limited to Colorado 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. Colorado (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.

Key Findings

Medicare revenue is highly concentrated: the precomputed top 3 codes by revenue account for 82.1% of this provider's total Medicare revenue, with J0178 alone representing $1.3M and 70.7% of the $1.8M Medicare total. This concentration indicates that most of the provider's Medicare income depends on high-volume intravitreal drug administration.

Clinical mix and service line align with retina specialty practice: the dominant code J0178 (1.8K claims, $690 avg paid/claim, $1.3M revenue) and additional injectable codes such as J2778 (323 claims) and Q5128 (195 claims) point to routine intravitreal pharmacologic therapy as the core service. High volumes of retinal imaging (92134: 1.8K claims, $32 avg paid/claim, $56.7K revenue) and established-patient comprehensive exams (92014: 1.1K claims, $92 avg paid/claim, $96.6K revenue) support an operating model built around recurring injection clinics with same-day or serial diagnostics.

Payer mix is effectively single-payer: the profile shows Total Medicare revenue of $1.8M and no Medicaid billing on file, so this provider operates at scale only in the Medicare program according to available data. Analysts should treat this as a Medicare-centric revenue base rather than a mixed Medicaid–Medicare practice.

Competitive standing on injections is solid but not dominant: J0178 ranks #601 of 3204 providers nationally (81th percentile; typical, unremarkable volume for this code), indicating substantial activity but not market-leading volume for aflibercept injections. By contrast, evaluation and imaging codes are comparatively strong — 92014 ranks #1495 of 35415 (96th percentile; notably above typical national volume) and 92134 ranks #1252 of 26868 (95th percentile; notably above typical national volume) — suggesting above-average throughput of office visits and OCT imaging relative to national peers.

Use of high-cost, low-volume drug codes is noticeable: J3590 (22 claims, $2120 avg paid/claim, $46.6K revenue) and J3490 (24 claims, $1695 avg paid/claim, $40.7K revenue) each contribute modest revenue but carry much higher avg paid/claim values and rank low nationally (J3590 ranks #563 of 631 providers nationally, 9th percentile; J3490 ranks #2482 of 2838 providers nationally, 12th percentile). These entries suggest infrequent use of unclassified biologics or bespoke drug billing that could reflect occasional off-label or specialty-supply purchases.

Operational tempo is consistent with chronic retinal disease management: high claim counts for recurring services — J0178 (1.8K claims), 92134 (1.8K claims), and 92014 (1.1K claims) — indicate a steady cadence of repeat visits, imaging, and injections typical of long-term intravitreal therapy protocols. This pattern implies predictable appointment and medication utilization cycles important for capacity and drug-supply planning.

Service breadth remains focused on ambulatory ophthalmology with adjunct diagnostics: beyond injections and OCT, the provider bills for ancillary retinal diagnostics and procedural codes such as 92235 (47 claims, $114 avg paid/claim), 92250 (230 claims, $20 avg paid/claim), and 76512 (35 claims), indicating in-office diagnostic imaging and photographic services commonly used in retinal disease monitoring. The presence of both evaluation (92014, 92004) and procedure codes (67028) confirms a combined clinic-and-procedure workflow.

Practice tenure is long-established: the NPI was enumerated 2006-05-11 (~20 years ago), indicating roughly two decades of enrollment and likely continuity of practice that aligns with the high cumulative Medicare revenue and recurring-treatment billing patterns observed. This longevity supports interpreting the current coding mix as steady-state practice behavior rather than a short-term anomaly.
