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

Why is the Medicaid comparison limited to Oregon 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. Oregon (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 reports $1.3M in total Medicare revenue and has no Medicaid billing on file, so the available billing footprint is effectively single‑payer Medicare. Analysts should treat utilization and revenue signals as Medicare-driven rather than a mixed‑payer profile when benchmarking or projecting volume.

Revenue is highly concentrated in a small number of drug codes: the top three Medicare codes account for 74.1% of the provider's Medicare revenue. J0178 alone represents 53.7% of Medicare revenue ($714.1K from 1K claims at $686 avg paid/claim), followed by J2777 with $179.3K (13.5% from 6.2K claims at $29 avg paid/claim) and J3490 with $92K (6.9% from 54 claims at $1703 avg paid/claim).

The code mix is consistent with a retina-focused, injection-centered practice: prominent intravitreal drug codes (J0178, J2777, J2781) plus procedure 67028 and high-volume retinal imaging 92134 indicate routine intravitreal injections with same-day or follow-up OCT imaging and E&M visits. Presence of J2781 (pegcetacoplan) and J7999 (compounded drug) further suggests treatment for macular disease and occasional use of compounded therapies.

Although J0178 produces a majority of the provider's Medicare dollars, the provider's national rank for J0178 is #1250 of 3204 (61th percentile) and the code is labeled "typical, unremarkable volume," meaning that the practice’s dependence on aflibercept is material to its revenue mix but not indicative of unusually high national utilization for that drug. In other words, the provider is not a national outlier for aflibercept volume despite that drug driving most revenue.

The practice shows clear areas of above‑peer activity in visit and imaging throughput: 99213 is ranked #11620 of 457151 (97th percentile, "notably above typical national volume") and 92134 is ranked #1609 of 26868 (94th percentile, "notably above typical national volume"). These rankings indicate higher-than-typical volumes of established-patient office visits and retinal OCT imaging relative to national peers, consistent with a high-frequency injection clinic model.

Other drug codes show more modest national standing: J2777 ranks #1369 of 2039 (33th percentile, "typical, unremarkable volume") and J2781 ranks #354 of 490 (26th percentile, "typical, unremarkable volume"). Those percentiles suggest variable adoption or lower per‑provider volume for some newer agents relative to the broader national cohort.

The provider's NPI was enumerated on 2007-02-27 (~19 years ago), reflecting long tenure in Medicare that supports sustained patient panels and recurring follow-up care typical of retina specialists. This tenure combined with high visit and imaging throughput suggests established referral relationships and ongoing management of chronic retinal disease.

From an operational and financial perspective, dependence on a small set of injectable biologics (top three codes = 74.1% of Medicare revenue) paired with unusually high E&M and OCT volumes implies that changes in drug reimbursement, supply, or utilization for J0178 and J2777 could meaningfully impact practice revenue. Analysts should monitor those drug codes and associated visit/imaging volumes when assessing revenue risk or planning network engagement.
