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

Why is the Medicaid comparison limited to Wisconsin 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. Wisconsin (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 is a retina specialist whose Medicare work is dominated by intravitreal drug therapy and related retinal procedures: J0178 shows 1.2K claims at $684 avg paid/claim generating $808.5K (60.1% of Medicare revenue), J2777 shows 5.1K claims at $29 avg paid/claim generating $147.9K (11.0%), and 67028 shows 1.1K claims at $97 avg paid/claim generating $106.3K (7.9%). The procedure and drug code mix (large volumes of anti-VEGF/anti‑retinal drugs plus intravitreal injection codes) is consistent with an outpatient retina practice focused on medical, injection‑based management of retinal disease rather than primary general ophthalmology.

Revenue is highly concentrated: the precomputed top 3 Medicare codes account for 79.1% of this provider's total Medicare revenue, indicating a business model heavily dependent on a small set of high‑value injection and related procedural codes. That concentration creates operational sensitivity to changes in reimbursement, drug utilization, or clinical guidelines affecting those specific codes.

The provider is effectively single‑payer from the claims perspective: lifetime Medicare revenue is $1.3M while there is no Medicaid billing on file. This lack of Medicaid activity means payers and analysts should treat Medicare reimbursement dynamics as the primary commercial exposure and revenue driver for this clinician.

Competitive standing across codes is mixed but not dominant nationally: J0178 ranks in the 65th percentile (described as "typical, unremarkable volume"), J2777 ranks in the 25th percentile (typical, unremarkable volume), and 67028 ranks in the 70th percentile (typical, unremarkable volume). In short, the provider shows solid, above‑median throughput on some retina procedures but does not appear as a national-volume outlier for the main anti‑VEGF code.

There are notable high‑relative‑volume signals in diagnostic imaging and some drug lines: 92134 (retinal imaging) is in the 94th percentile and labeled "notably above typical national volume," while J9035 (bevacizumab) is in the 92th percentile but labeled "typical, unremarkable volume." The combination of very high retinal imaging volume and elevated bevacizumab claims supports a practice pattern of frequent monitoring paired with active pharmacologic therapy.

Surgical retina activity is present but smaller in scale compared with injection therapy: 67042 (vitrectomy with internal limiting membrane work) shows 45 claims at $857 avg paid/claim producing $38.6K (2.9% of Medicare revenue), and 67108 (retinal detachment repair) shows 16 claims at $862 avg paid/claim producing $13.8K (1.0%). These figures indicate the clinician performs some operative retinal procedures but derives the bulk of Medicare revenue from injections and imaging.

The provider has an established billing history with an NPI enumerated on 2006-08-30 (~20 years ago), suggesting a long tenure in the market. Given that tenure, lifetime Medicare revenue of $1.3M signals a steady, mid‑scale Medicare practice rather than a large integrated retinal center.

There is a pronounced disparity in revenue per claim across key drug lines that affects revenue composition: J0178 averages $684 paid/claim while J2777 averages $29 paid/claim, and these two codes together (with 67028) produce most of the revenue. Analysts should note that differences in avg paid/claim and claim counts (unitization and drug pricing) substantially shape the provider's Medicare revenue profile and sensitivity to changes in drug utilization or reimbursement policy.
