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

Why is the Medicaid comparison limited to Missouri 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. Missouri (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 business is highly concentrated in intravitreal anti-VEGF therapy: J0178 (aflibercept) accounts for $1.9M in revenue and 70.6% of Medicare revenue with 2.8K claims, and the top three Medicare codes together account for 90.5% of total Medicare revenue. The heavy weighting to J0178, supplemented by J2777 (faricimab) and 67028 (vitreous injection), indicates a service line organized around high-volume medical retina injections rather than diversified outpatient procedures.

J0178’s national placement (#219 of 3204; 93th percentile) is described as notably above typical national volume, signaling that this clinician is a major dispenser of aflibercept relative to peers. By contrast, J2777 ($426.3K; 14.7K claims) ranks #729 of 2039 (64th percentile) and 67028 ($119.6K; 1.4K claims) ranks #854 of 4255 (80th percentile), both characterized as typical or unremarkable volumes—so dominance is concentrated specifically in aflibercept.

Clinical operations appear oriented to frequent follow-up and diagnostic imaging that support injection-based retina care: 92012 (intermediate established eye exam) has 1.5K claims and $84K revenue and ranks #181 of 17177 (99th percentile; extreme outlier), and 92134 (retinal imaging/OCT) has 2.3K claims and $60.9K revenue and ranks #760 of 26868 (97th percentile; extreme outlier). These two extreme outlier designations, alongside the injection codes, point to a high-throughput retina clinic model with repeated visits and imaging to manage chronic retinal conditions.

Despite the injection and diagnostic intensity, surgical retina activity is limited: 67108 ($10.6K; 13 claims) ranks #508 of 706 (20th percentile) and 67041 ($9.9K; 12 claims) ranks #379 of 461 (8th percentile), both noted as typical or unremarkable volumes and low percentiles. This split suggests the provider predominantly manages medical retina (intravitreal therapy and imaging) rather than performing a substantial volume of vitreoretinal surgeries.

Payer mix is effectively single-payer Medicare: lifetime Medicare revenue totals $2.7M while there is no Medicaid billing on file, so the practice has no recorded Medicaid revenue and appears to operate almost entirely within the Medicare population. This concentration on Medicare may shape contracting exposure and risk segmentation, as the provider lacks a Medicaid panel footprint.

Several non-procedural E/M and new-patient codes are unusually high relative to peers: 99204 ($27.8K) ranks #1936 of 227068 (99th percentile; extreme outlier), indicating above-typical volume of moderate-complexity new-patient visits, while lower-level established visit codes such as 99213 and 99214 are present at small absolute volumes and low national ranks. The mix implies the practice handles a steady stream of new or complex consults paired with high-frequency established-patient follow-ups tied to injection therapy.

Tenure and stability are evident in enrollment data: the NPI was enumerated on 2013-04-30 (~13 years ago), which supports an established local presence in Columbia, MO and provides a multi-year claims footprint for assessing longitudinal utilization trends. Analysts should treat observed code concentration and outlier status in the context of a long-standing outpatient retina practice.

From a competitive standpoint, the provider is a significant national-level participant for aflibercept delivery (J0178 notably above typical national volume) and an extreme outlier in routine retinal imaging and intermediate established exams (92012, 92134). For payers evaluating network adequacy or utilization, this profile identifies the clinician as a high-volume medical retina resource for Medicare beneficiaries but not a broad Medicaid or surgical retina resource.
