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.

The Medicare and Medicaid tables are both single current snapshots, not refreshed on a recurring schedule yet.

Key Findings

This provider’s billing is effectively single-payer: Total Medicare revenue is $6.2M and there is no Medicaid billing on file. The absence of Medicaid activity means the provider’s public payer exposure and contracting dynamics are dominated by Medicare reimbursement patterns rather than a mixed Medicaid/Medicare panel.

Revenue is highly concentrated: the precomputed top 3 codes account for 75.0% of this provider’s total Medicare revenue, driven primarily by J0178 (53.4% of Medicare revenue, $3.3M), followed by J3490 (13.3%, $831.3K) and J2778 (8.3%, $517K). This concentration indicates the practice’s financial performance is heavily dependent on a small set of high-value drug codes.

The code mix and volumes point to a retina-focused ophthalmology practice centered on intravitreal biologic therapy and imaging. High volumes for intravitreal drug codes (J0178, J2778, J2781, J2777) plus procedure code 67028 and imaging code 92134 suggest routine, repeated injection visits with accompanying retinal diagnostics rather than a broad general ophthalmology case mix.

CHARLES WYKOFF is a national outlier on aflibercept billing: J0178 ranks #30 of 3204 providers nationally (99th percentile) and is labeled an extreme outlier, far above typical national volume for this code. At 4.8K claims and $688 avg paid/claim, the scale of J0178 activity makes the provider a dominant national participant for that specific drug.

Several additional codes are well above typical national volume or flagged as extreme outliers for diagnostic and therapeutic retina care. J2781 ranks #13 of 490 (98th percentile, notably above typical national volume) and 92134 and 92014 both rank in the 99th percentile and are described as extreme outliers; 67028 also ranks highly (96th percentile, notably above typical national volume). Together these ranks reinforce a high-intensity retina service line with both treatment and diagnostic intensity.

Some high-revenue lines are coded to unclassified categories: J3490 (419 claims, $1984 avg paid/claim, $831.3K) and J3590 (102 claims, $1953 avg paid/claim, $199.2K) together represent notable revenue but are described as typical, unremarkable volumes for those unclassified codes. The presence of material revenue under unclassified drug/biologic codes suggests mix or billing of products that may not map cleanly to single, specific HCPCS entries and is worth review when reconciling clinical supplies to paid drug spend.

Operational tenure is substantial: the NPI was enumerated on 2007-05-22 (~19 years ago), indicating a long-established billing history that is consistent with sustained high-volume specialty practice rather than a recent or transient billing pattern. This longevity strengthens the interpretation that the observed injection and imaging volumes reflect an ongoing clinical focus rather than a short-term spike.

From a payer risk and contract-management perspective, the practice’s heavy reliance on a few high-cost biologic codes (notably J0178) and on intensive retina diagnostics/procedures concentrates utilization and payment risk. Given that top codes account for 75.0% of Medicare revenue, payers and network managers may prioritize drug-utilization oversight, reimbursement strategy, and outcomes alignment for intravitreal biologics when engaging this provider.
