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

Why is the Medicaid comparison limited to Colorado 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. Colorado (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

MIMI LIU is a retina specialist (Ophthalmology) in ENGLEWOOD, CO with an NPI enumerated 2005-07-05 (~21 years ago) and lifetime Medicare revenue of $2.2M; there is no Medicaid billing on file. This is effectively a single-payer Medicare billing profile, with Medicaid revenue reported as none, which concentrates attribution and reimbursement exposure on Medicare rules and pricing.

Revenue is highly concentrated in anti-VEGF drug administration: J0178 alone accounts for $1.7M and 76.7% of the provider's Medicare revenue, and the precomputed top-3 codes collectively account for 86.9% of total Medicare revenue. That profile indicates the practice’s financial performance is dominated by intravitreal injection services tied to high-cost biologic drugs.

The procedural mix reinforces a medical-retina infusion model: J0178 (2.5K claims, $692 avg paid/claim), J2778 (578 claims, $181 avg paid/claim, $104.6K revenue), and J2777 (3.2K claims, $29 avg paid/claim, $92.2K revenue) are among the top revenue-generating codes, showing routine use of intraocular injections and multiple anti-VEGF agents/formulations. Combined billing for diagnostic imaging codes such as 92134 (1.7K claims, $32 avg paid/claim, $53.2K revenue) and fundus photography 92250 (189 claims, $22 avg paid/claim, $4.2K revenue) indicates the practice delivers both therapeutic injections and on-site retinal imaging.

Competitive standing by code is mixed: J0178 ranks #334 of 3204 providers nationally (90th percentile), which places the provider well above many peers on aflibercept use but is described as "typical, unremarkable volume" in the source labels; 92134 ranks #1362 of 26868 (95th percentile) and is labeled "notably above typical national volume," indicating comparatively high retinal imaging throughput. By contrast, codes like J2777 (rank #1797 of 2039, 11th percentile) and Q5128 (rank #322 of 373, 14th percentile) sit at low national percentiles, suggesting limited use of those specific products relative to peers.

Visit-level and E/M activity is present but secondary to injection revenue: 92014 shows 712 claims and $68.4K revenue (3.1% of Medicare revenue) and 92004 appears for new comprehensive visits (56 claims, $6.5K), while E/M codes such as 99204/99214 appear at low volumes. These counts suggest the practice combines procedural injection sessions with periodic comprehensive and established ophthalmology visits rather than high-volume general primary eye care.

The provider bills care-management/coordination codes in small volumes (99426: 66 claims, $3.3K; 99427: 58 claims, $2.3K), which indicates some engagement in chronic care management for complex patients but not at a scale that materially shifts revenue composition. This pattern is consistent with a retina-focused practice that bills targeted clinical staff time alongside primary therapeutic procedures.

From an operational and reimbursement exposure standpoint, dependence on a single drug code (J0178 at $1.7M and 76.7% of Medicare revenue) creates sensitivity to changes in drug pricing, reimbursement policy, or utilization management for aflibercept; the top-3 concentration of 86.9% amplifies that dependence. The provider’s long tenure (NPI enumerated 2005-07-05, ~21 years) suggests an established referral base and operational continuity that likely supports the high injection volume.

Several codes are labeled as "typical, unremarkable volume" despite high absolute dollars (e.g., J0178 is in the 90th percentile and described as typical), so while the provider is a meaningful national-level user of aflibercept, it is not characterized in the source data as an extreme outlier beyond the expected range for high-volume retina specialists. The presence of a "notably above typical" ranking for 92134 reinforces that the practice stands out more on diagnostic retinal imaging throughput than on every component of drug therapy coding.
