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

Why is the Medicaid comparison limited to Hawaii 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. Hawaii (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

DAVID TAMURA is a Hematology & Oncology Physician based in HONOLULU, HI with NPI enumerated (registered): 2007-04-24 (~19 years ago). Lifetime Medicare revenue on file is $373.7K and there is no Medicaid billing on file, indicating Medicare is his sole reported public-payer source in these records.

Revenue is highly concentrated: the precomputed top 3 Medicare codes account for 61.6% of this provider's total Medicare revenue. The single largest revenue driver is 99214 ($157K, 43.0% of Medicare revenue), followed by J0897 ($48.1K, 13.2%) and 99232 ($20K, 5.5%).

The mix of codes suggests a clinic-based oncology practice that couples high-volume outpatient evaluation & management with infusion and supportive care services. High-ranking office E/M codes (99214, 99215, 99213), chemotherapy/infusion administration codes (96413, 96402, 96365, 96367), and injectable oncology-related drugs (J0897 denosumab, J0885 epoetin alfa) together with frequent lab orders point to routine in-office chemo/infusion and close laboratory monitoring.

This provider is effectively single-payer in the public claims data: Medicare revenue is $373.7K and there is "none below" for Medicaid — the absence of Medicaid billing on file means in-state Medicaid activity cannot be assessed and payer negotiations or access patterns should be considered Medicare-centric.

For the dominant office visit code 99214, the provider ranks #2982 of 479517 nationally (99th percentile; extreme outlier, far above typical national volume for this code), indicating an unusually high national volume for this specific E/M service and signaling a heavy outpatient visit load relative to peers. This standing is consistent with a high-volume clinic or concentrated patient panel for complex outpatient management.

Infusion and chemotherapy codes show more typical competitive positioning: J0897 ranks #5184 of 10057 (48th percentile; typical, unremarkable volume for this code), 96413 ranks #3684 of 7514 (51th percentile; typical, unremarkable volume for this code), and J0885 ranks #565 of 953 (40th percentile; typical, unremarkable volume for this code). These ranks suggest the provider administers these agents regularly but does not appear dominant nationally in chemotherapy or drug administration volume.

Ancillary and lab activity is prominent and concentrated in relatively high percentiles, supporting active patient monitoring on-site. Examples include 85025 (1.4K claims, $11.3K revenue; ranks #1538 of 32833, 95th percentile; typical, unremarkable volume for this code), 80048 (1.3K claims, $10K revenue; ranks #368 of 14725, 98th percentile; typical, unremarkable volume for this code), 80076 (1.2K claims, $9.9K revenue; ranks #160 of 3400, 95th percentile; typical, unremarkable volume for this code), and 36415 (1.3K claims, $6.7K revenue; ranks #1797 of 86467, 98th percentile; typical, unremarkable volume for this code).

Presence of inpatient/observation E/M codes indicates some hospital-based care in addition to the outpatient practice: 99232 (318 claims, $20K revenue; ranks #28580 of 177383, 84th percentile; typical, unremarkable volume for this code), 99222 (61 claims, $6.3K revenue; ranks #23379 of 117621, 80th percentile; typical, unremarkable volume for this code), and 99223 (30 claims, $4.2K revenue; ranks #83345 of 139583, 39th percentile; typical, unremarkable volume for this code). This mix implies the provider manages both clinic visits and a measurable amount of inpatient/observation follow-up or consults.
