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.

How current is this data?

The Medicare and Medicaid tables are both single current snapshots, not refreshed on a recurring schedule yet.

Key Findings

DINA DOMALANTA-VILLALUNA is listed as a Pediatrics Physician in TAMUNING, GU with an NPI enumerated on 2007-01-04 (~19 years ago), indicating long-standing enrollment in federal programs. The tenure suggests potential continuity in practice but does not by itself indicate current billing volume or scale across payers.

This provider has no Medicare billing on file and therefore appears to operate, in the available federal claims data, effectively as a single-payer (Medicaid) biller. Total Medicaid revenue is $2.3K, and there is no recorded Medicare revenue to compare against.

Revenue concentration within Medicaid is extremely narrow: the precomputed top 3 Medicaid codes account for 100.0% of this provider's total Medicaid revenue. This indicates that Medicaid billing activity is focused on a very small set of service lines rather than a diversified code mix.

The sole listed Medicaid code driving revenue is 99213 (27 claims, $87 avg paid/claim, $2.3K revenue (100.0% of this provider's total Medicaid revenue)). Code 99213 represents an established patient office/outpatient visit with a low level of medical decision making or ~20+ minutes of total time, which is consistent with routine ambulatory pediatric visits and follow-up care rather than high-acuity or procedural work.

Competitive standing on the cited Medicaid code is modest: the provider ranks #45 of 48 providers in-state (6th percentile; typical, unremarkable volume for this code). That rank indicates the provider is a small-volume participant in the state market for 99213 rather than a major or dominant Medicaid outpatient pediatric provider.

The narrow code mix and absence of procedural or inpatient codes in the Medicaid data suggest low procedural intensity and a practice profile centered on routine office-based pediatric care. This pattern is consistent with a clinic or part-time outpatient practice model focused on established patient visits.

Operationally, the small Medicaid revenue and low claim count imply limited Medicaid-facing activity and correspondingly limited leverage in payer negotiations or network influence. Such a profile could reflect a practice that primarily serves non-Medicaid populations, has minimal Medicaid panel size, or uses alternative payers not captured here, but the data on file do not specify which of these applies.

Analysts should note the data limitations: with no Medicare claims and only $2.3K in Medicaid revenue concentrated in 99213, conclusions about broader practice scale, commercial payer activity, or affiliations are constrained. For fuller competitive or capacity analysis, supplement these federal claims observations with state Medicaid encounter detail, commercial claims, or provider affiliation records.
