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.

This provider is effectively a Medicaid-only practitioner: there is no Medicare billing on file while lifetime Medicaid revenue totals $334.5K, indicating that the provider’s patient panel and reimbursement activity are concentrated in the Medicaid program rather than in Medicare or dual-eligible populations. Analysts should treat payer mix as single-payer–dominated for operational and access evaluations.

Revenue concentration is high: the precomputed top three Medicaid codes account for 85.2% of the provider’s total Medicaid revenue, signaling that a small set of outpatient E/M and vaccine-related services drive the majority of receipts. This suggests that the practice’s financial performance is sensitive to changes in reimbursement or volume for those specific codes.

The clinic’s principal revenue driver is 99213, which generated $173.4K (51.9% of Medicaid revenue) across 1.8K claims and ranks #17 of 48 in-state (66th percentile). This places the provider in the middle of state peers for standard established-patient office visits, consistent with a general pediatric outpatient practice delivering routine sick and follow-up care.

The second major contributor is 99212, with $78.4K (23.4% of Medicaid revenue) from 1.4K claims and a state rank of #4 of 21 (85th percentile). High relative rank on 99212 versus peers indicates above-typical volume for straightforward established-patient visits, implying the clinic sees many low-acuity follow-ups or quick visits common in pediatric primary care.

Vaccination administration codes (notably 90461 and 90460) comprise meaningful, but smaller, revenue shares: 90461 produced $33.2K (9.9% of Medicaid revenue) from 873 claims while 90460 produced $29.8K (8.9% of Medicaid revenue) from 1.8K claims. The presence of numerous zero-paid vaccine product codes with high claim counts (e.g., 90658, 90670, 90700) further indicates that the practice performs substantial immunization services, although many of those product codes appear to show $0 paid in this dataset and therefore do not contribute materially to billed revenue.

Competitive standing is mixed by code: for core office visits the provider is a modest-to-strong participant — 99213 is typical volume (66th percentile) while 99212 is notably above typical (85th percentile) among state peers — suggesting solid local market share for straightforward pediatric visits but not dominance across all E/M levels. For many vaccine product codes the provider ranks at or near #1 in-state but those lines show $0 revenue, so while the practice may be a high-volume vaccine administrator, the fiscal impact of those specific product codes in these records is limited.

Tenure is long: the provider’s NPI was enumerated on 2007-04-16 (~19 years ago). This extended enrollment duration supports interpretation of these activity patterns as established rather than transient, which is relevant when evaluating referral relationships, continuity of care capacity, and potential contractual negotiating leverage with payers.
