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

Why is the Medicaid comparison limited to Massachusetts 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. Massachusetts (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

DELIA SANG is an Ophthalmology Physician in BROOKLINE, MA with lifetime Medicare revenue of $2.7M and no Medicaid billing on file; the NPI was enumerated 2005-12-20 (~21 years ago), indicating an established practice tenure. The absence of any Medicaid activity (none below) makes this effectively a single-payer Medicare practice from a billing perspective, concentrating commercial/patient exposure on the Medicare population.

Revenue concentration is high: the precomputed top 3 Medicare codes by revenue account for 79.5% of this provider's total Medicare revenue, driven by J0178 ($1.2M, 42.3%), J2777 ($863K, 31.7%), and 67028 ($150.1K, 5.5%). This degree of concentration signals the business is heavily dependent on a small set of intravitreal injection–related services for the bulk of its income.

The code mix and descriptions point to a retina-focused, procedure-driven operation: large revenues for J0178 (aflibercept) and J2777 (faricimab) plus 67028 (intravitreal injection) indicate ongoing anti-VEGF treatment as a core service line. Complementary high-volume diagnostic imaging codes (see 92134 and 92250 below) and frequent E/M claims (92014, 99213) support a workflow centered on recurrent injections with serial retinal monitoring.

Competitive standing for the primary injection codes is modest rather than dominant: J0178 ranks #715 of 3204 providers nationally (78th percentile; typical, unremarkable volume for this code), J2777 ranks #301 of 2039 providers nationally (85th percentile; typical, unremarkable volume for this code), and 67028 ranks #717 of 4255 providers nationally (83th percentile; typical, unremarkable volume for this code). In plain terms, the provider participates in a common national service line for intravitreal therapy at volumes that are within typical peer ranges rather than being a national leader.

In contrast, several diagnostic and office-visit codes show exceptional relative volume: 92134 has 3.5K claims and $124.1K revenue and ranks #216 of 26868 providers nationally (99th percentile; extreme outlier, far above typical national volume for this code); 92250 reports 1.6K claims and $51.7K revenue and ranks #70 of 25087 providers nationally (100th percentile; extreme outlier, far above typical national volume for this code); and 99213 shows 1.5K claims and $116.2K revenue and ranks #1944 of 457151 providers nationally (100th percentile; extreme outlier, far above typical national volume for this code). These extreme outlier labels indicate the practice is a high-throughput center for retinal imaging and routine follow-up visits relative to national peers.

Operationally, the revenue and utilization mix suggests a model that pairs high-frequency, lower-dollar diagnostic imaging (e.g., 92134 at $35 avg paid/claim) with recurring higher-dollar therapeutic injections (e.g., J0178 at $692 avg paid/claim). That combination is consistent with a retina clinic relying on serial monitoring and repeat intravitreal treatments, which creates steady, treatment-driven revenue but also concentrates financial performance on episodic drug administration and imaging throughput.

The lack of Medicaid activity (none below) exposes the practice to payer-concentration risk — commercial and Medicare reimbursement dynamics will largely determine revenue stability. For payer/provider analysts, this single-payer profile reduces complexity for Medicaid network planning but highlights sensitivity to Medicare policy changes affecting J0178, J2777, and related injection/imaging reimbursement.

Taken together, long tenure since 2005-12-20 (~21 years ago), heavy revenue concentration in three injection codes (79.5% of Medicare revenue), and extreme outlier status on retinal imaging and routine E/M volumes suggest an established, retina-oriented practice that functions as a high-volume diagnostic and therapeutic center for Medicare beneficiaries rather than a broad-based multispecialty outpatient practice. Analysts should consider the operational implications of dependence on repeated anti-VEGF therapy and retinal imaging when assessing competitive positioning and revenue resilience.
