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

Why is the Medicaid comparison limited to Texas 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. Texas (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 on file: total Medicare revenue is $4.7M and there is no Medicaid billing on file, indicating an effectively single‑payer (Medicare) revenue base for the claims observed. That payer concentration means patient mix and revenue depend heavily on Medicare beneficiaries rather than state Medicaid volumes.

Revenue is highly concentrated in a small number of high‑value codes: the precomputed top‑three Medicare codes account for 80.2% of the provider’s Medicare revenue, driven overwhelmingly by J0178 (4.6K claims, $3.2M revenue, 67.1% of total Medicare revenue). J2777 (14.9K claims, $416.6K revenue, 8.8%) and 67028 (2.1K claims, $207.4K revenue, 4.4%) complete that top trio, so a few procedural/drug lines account for the bulk of dollars.

The code mix and descriptions identify a retina‑focused ophthalmology practice centered on intravitreal drug delivery and retinal diagnostics: high volumes for J0178 (aflibercept injections) and J2777 (faricimab) alongside substantial utilization of retinal imaging 92134 (3.6K claims, $104K) and injection procedure 67028 (2.1K claims, $207.4K) indicate routine in‑office anti‑VEGF and related intravitreal therapies. This pattern is consistent with a clinic operating an injection suite and performing frequent retinal imaging to guide treatment.

On competitive standing, the provider is an outlier nationally for several key procedures. J0178 ranks #39 of 3204 providers nationally (99th percentile; extreme outlier) and 92134 ranks #207 of 26868 (99th percentile; extreme outlier), while 92014 (established comprehensive exam) ranks #237 of 35415 (99th percentile; extreme outlier), indicating much higher than typical volumes nationally for these services and a dominant position on those specific codes.

Not all drug codes show the same dominance: while J0178 is an extreme outlier, other biologic and drug codes have more typical volumes versus peers. For example, J2777 (14.9K claims, $416.6K) ranks #720 of 2039 providers (65th percentile; typical) and Q5128 (694 claims, $151.3K) ranks #182 of 373 providers (51th percentile; typical), suggesting concentrated leadership on aflibercept specifically but more ordinary participation in other biologic agents.

The practice also generates substantial evaluation and management and diagnostic activity, supporting a sustained patient panel and follow‑up flow: 92014 (2K claims, $187.1K) and 92012 (1.5K claims, $77.5K) both appear at the 99th percentile nationally, and 99204 (253 claims, $28.1K) similarly ranks in the 99th percentile, consistent with high throughput of both established and new patient office encounters in addition to procedure volume.

The high dollar amount per claim for certain unclassified drug codes contributes materially to revenue but does not show outsized national ranking: J3490 (52 claims, $94.4K revenue, $1816 avg paid/claim) ranks #1560 of 2838 providers (44th percentile), indicating that a small number of expensive miscellaneous drug claims add to revenue without the same peer dominance seen with J0178.

Operational and strategic sensitivity is suggested by the heavy reliance on a small set of drug and injection codes: with J0178 representing $3.2M (67.1% of Medicare revenue) and the top three codes accounting for 80.2% of Medicare revenue, changes in reimbursement, drug availability, or clinical guidelines affecting these products or procedures could materially impact revenue. The provider’s long tenure (NPI enumerated 2007-05-21, ~19 years ago) implies established referral and clinical workflows that have supported this focused service mix over time.
