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

Why is the Medicaid comparison limited to Mississippi 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. Mississippi (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 practice is heavily focused on intravitreal drug therapy and retina care: the top revenue driver is J0178 (aflibercept) with 1.1K claims and $742.4K revenue (63.9% of this provider's total Medicare revenue), and the procedural code 67028 (intravitreal injection) appears as a top procedural line with 928 claims and $82.6K revenue. The code mix — high-volume anti-VEGF administration plus retinal procedure codes — indicates an operation organized around frequent in-office injections and retina-specific interventions rather than general ophthalmology procedures alone.

Revenue is highly concentrated in a small set of Medicare codes: the precomputed top-3 Medicare codes account for 80.9% of this provider's total Medicare revenue, led by J0178 at 63.9%, followed by J2777 at 9.9% and 67028 at 7.1%. That concentration means changes in utilization patterns or payer policy for these few codes could materially affect the provider’s Medicare revenue.

The provider’s payer mix is effectively single-payer Medicare at scale: lifetime Medicare revenue is $1.2M while there is no Medicaid billing on file. This lack of Medicaid activity suggests minimal exposure to Medicaid reimbursement risk and a patient panel or contracting footprint that does not rely on state Medicaid revenue.

On competitive standing for key injection codes, the provider’s J0178 activity ranks #1214 of 3204 providers nationally (62th percentile; typical, unremarkable volume for this code), indicating a modest, but not dominant, national presence for aflibercept administration. J2777 activity ranks #1684 of 2039 (17th percentile; typical, unremarkable volume), showing relatively lower national activity for faricimab, while 67028 ranks #1480 of 4255 (65th percentile; typical, unremarkable volume), placing the provider slightly above typical national procedural volume for intravitreal injections.

Diagnostic imaging is a notable strength: 92134 shows 1.3K claims, $34.9K revenue (3.0% of Medicare revenue) and ranks #1700 of 26868 providers nationally (94th percentile; notably above typical national volume). Alongside 92134, standard ophthalmology visit codes appear but at smaller revenue shares, indicating the practice pairs high-volume retinal imaging with injection services to support disease monitoring and treatment decisions.

The practice generates very little E/M and ancillary billing relative to procedural lines: 99213 and 99214 together account for only $507 and $448 in Medicare revenue, with national ranks in the low percentiles, and 92250 fundus photography is minimal at $575. This pattern reinforces that the revenue model is procedure-driven (injections and imaging) rather than office-visit-based evaluation and management.

There is evidence of a mixed pharmaceutical strategy: Q5128 (ranibizumab biosimilar) contributed $69.3K (6.0% of Medicare revenue) and ranks #265 of 373 (29th percentile; typical, unremarkable volume), while J9035 (bevacizumab) contributed $24.5K and ranks #306 of 1852 (84th percentile; typical, unremarkable volume). The presence of branded biologic (J0178), biosimilar (Q5128), and bevacizumab usage suggests the provider uses multiple anti-VEGF agents rather than a single-product approach.

This NPI has long tenure in billing: enumerated on 2007-07-06 (~19 years ago), which indicates a sustained practice presence in the market; total reported Medicare lifetime revenue of $1.2M places the provider as a mid-scale Medicare biller within ophthalmology given the specialization in intravitreal services. The combination of long tenure, concentrated procedural revenue, and no Medicaid activity frames this clinician as an established, procedure-focused Medicare provider with limited state payer exposure.
