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

Why is the Medicaid comparison limited to North Carolina 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. North Carolina (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

VISHAK JOHN is an Ophthalmology Physician in WINSTON SALEM, NC with lifetime Medicare revenue of $4.3M and no Medicaid billing on file; the provider’s NPI was enumerated 2007-12-20 (~19 years ago), indicating nearly two decades of participation in Medicare. This profile makes the provider effectively single-payer (Medicare) in the dataset rather than balanced across Medicaid and Medicare.

The top 3 Medicare codes by revenue account for 84.2% of this provider's total Medicare revenue, with J0178 contributing 43.1%, J2777 contributing 31.8%, and J2778 contributing 9.3%. That extreme concentration on three codes indicates revenue is heavily driven by a narrow set of drug-injection services rather than a broad mix of office or surgical revenues.

Service-line mix is retina-centric: the dominant codes J0178, J2777, and J2778 are all intravitreal injections for anti-VEGF or related agents, and high-volume diagnostic codes such as 92134 and 92014 further support a practice organized around frequent injection visits and retinal imaging. Lower-volume vitrectomy and retinal repair codes (for example 67041, 67036, 67108) appear in the mix but represent a much smaller share of revenue, suggesting the operation is primarily an injection-and-image ambulatory retina practice with some surgical capacity.

On competitive standing for key injection drugs, the provider shows above-typical national volume for J2777 (rank #123 of 2039, 94th percentile; notably above typical national volume) and solid-but-not-dominant volume for J0178 (rank #258 of 3204, 92th percentile; labeled typical, unremarkable volume) and J2778 (rank #197 of 1208, 84th percentile; typical, unremarkable volume). In plain terms, this provider is a relatively high-volume user of faricimab (J2777) nationally while maintaining typical national volumes for other anti-VEGF agents.

Diagnostic and follow-up services are markedly elevated: 92014 is ranked #168 of 35415 (100th percentile; extreme outlier, far above typical national volume) and 92134 is ranked #224 of 26868 (99th percentile; extreme outlier, far above typical national volume). These extreme outlier positions for comprehensive established-patient exams and OCT imaging indicate heavy throughput of monitored retinal disease patients, consistent with frequent injection visits and close disease surveillance.

Several procedure-level signals underscore how care is delivered: 67028 shows 2.2K claims and $208.1K revenue (4.9% of Medicare revenue) with rank #299 of 4255 (93th percentile; notably above typical national volume), which aligns with frequent isolated intravitreal procedures billed separately. At the same time, operative retinal procedures (e.g., 67041, 67036) are present but account for single-digit percentages of revenue, pointing to a business model centered on medical retina care rather than surgery.

Payer-mix implications are clear: with $4.3M in Medicare revenue and no Medicaid billing on file, this provider is effectively single-payer in the available dataset. That concentration means revenue exposure and contract negotiations will be driven by Medicare reimbursement trends and changes to drug coverage or payment for intravitreal services, rather than shifts in state Medicaid behavior.

From an operational and financial perspective, heavy dependence on a few high-revenue drug codes and on frequent follow-up imaging/exam visits suggests both a capacity advantage for delivering repeat injections and a vulnerability to changes in reimbursement or drug utilization patterns. The combination of being a national high-volume reporter for J2777 and extreme outlier volumes for 92014 and 92134 implies a well-established care pathway and patient flow optimized for recurrent retinal therapy visits.
