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

Why is the Medicaid comparison limited to Guam 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. Guam (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.

Key Findings

This provider is a Pain Medicine (Anesthesiology) Physician based in TAMUNING, GU with an NPI enumerated 2010-09-26 (~16 years ago), indicating more than a decade of billing history in the Medicare program. The specialty-aligned code mix — a combination of E/M office visits, trigger point and joint injections, and anesthesia for ocular procedures — supports a practice that blends outpatient pain management with procedure-based anesthesia services.

Medicare is the sole payer of recorded revenue for this provider: lifetime Medicare revenue is $48.1K while Medicaid shows none (no Medicaid billing on file), making this an effectively single-payer (Medicare-only) billing profile in the available data. Analysts should treat the provider as operating without measurable Medicaid activity when modeling local payer mix or network coverage.

Revenue concentration is high: the top three Medicare codes (99213, 99205, and 00142) together account for 67.5% of total Medicare revenue, signaling dependence on a small set of service lines. Individually those codes generated $16.8K (99213), $8K (99205), and $7.8K (00142), so office E/M visits and anesthesia for eye lens procedures are the primary revenue drivers.

The service mix indicates a hybrid office-and-procedural operation: substantial billing for 99213 (247 claims, $68 avg paid/claim, $16.8K) and 99205 (48 claims, $166 avg paid/claim, $8K) shows routine new and established patient visits, while 00142 (76 claims, $102 avg paid/claim, $7.8K) and 00145 reflect anesthesia activity related to ophthalmic surgery. Complementary procedure codes such as 20553 (89 claims, $49 avg, $4.4K) and 20552 (60 claims, $39 avg, $2.3K) further point to office-based injection therapy as a meaningful part of clinical volume.

National competitive standing across the top codes is generally ‘‘typical, unremarkable volume’’ rather than dominant: 99213 ranks #76783 of 457151 (83th percentile), 99205 ranks #14502 of 66257 (77th percentile), and 00142 ranks #5025 of 19760 (74th percentile). These percentiles describe a modest-to-moderate national presence for the provider’s highest-revenue services rather than top-tier market leadership.

There are no strong statistical outliers in the reported labels for high-revenue services; most listed codes are described as ‘‘typical, unremarkable volume for this code,’’ which implies the provider’s coding and volumes generally fall within expected ranges for peers rather than exhibiting unusual concentration or extreme deviation. However, some lower-revenue or less-common anesthesia codes (for example 00145, 11 claims, $148 avg paid/claim, $1.6K) appear in small absolute volumes and should be monitored for episodic use rather than core lines.

Drug administration codes generate negligible Medicare revenue for this provider: J1030 produced $330 (55 claims) and J1100 shows 117 claims with $0 revenue. This suggests either low utilization of billable injectable pharmaceuticals in Medicare or reimbursement patterns that yield minimal paid revenue for those drug codes in this practice.

For network development and competitive analysis, the practice should be categorized as a small, procedure-capable pain medicine provider whose Medicare income ($48.1K lifetime) is concentrated in a few E/M and anesthesia codes and who reports no Medicaid activity. Payors evaluating contracting or utilization management should focus on the top three codes (which together supply 67.5% of Medicare revenue) and treat Medicaid-related considerations as currently non-applicable based on the file.
