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.

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

Key Findings

This provider is effectively single-payer in scope: there is no Medicare billing on file while lifetime Medicaid revenue is $2.4M, indicating the practice’s revenue stream is driven entirely by Medicaid reimbursements rather than a mixed Medicare/Medicaid payer mix. That concentration should be treated as a defining feature of the business profile and will strongly shape competitiveness and payer risk.

Revenue is highly concentrated in a small set of Medicaid codes: the top three Medicaid codes (D4220, D7140, D0150) account for 47.3% of Medicaid revenue, with D4220 generating $706K (29.3%), D7140 $232.6K (9.7%), and D0150 $198.5K (8.3%). Those three codes function as the primary revenue drivers and deserve priority attention for rate negotiation, utilization monitoring, and any audit or policy-change impact analysis.

The code mix indicates a high-volume general dental practice with substantial pediatric and restorative activity: high counts and payments for D0150 (comprehensive oral evaluation), D1120 (Prophylaxis–child), D1351 (Sealant), and amalgam codes like D2150 point to routine preventive care, fillings, and new-patient/comprehensive evaluations as core services. The presence of D7140 (extraction, erupted tooth or exposed root) as a top revenue code also indicates a significant surgical/extraction workload alongside preventive and restorative services.

State-level competitive standing is modest-to-solid rather than dominant: flagship codes sit in the upper half of in-state distributions but do not show market leadership — D4220 ranks #4 of 8 (57th percentile), D7140 ranks #3 of 7 (67th percentile), and D0150 ranks #4 of 10 (67th percentile). Multiple common codes fall in the 60th–80th percentile range (for example, D0120 at the 80th and D0220 at the 79th), suggesting the practice consistently generates above-average volume on many routine procedures without dominating the state market.

Preventive and imaging services are a clear volume strength: high claim counts for radiographic and evaluation codes (D0230: 3.2K claims, $118.3K revenue, 75th percentile; D0220: 3.7K claims, $52.2K revenue, 79th percentile; D0120: 2.7K claims, $109.5K revenue, 80th percentile) show steady throughput of examinations and intraoral imaging that supports the practice’s restorative and preventive workflows. This pattern reinforces the characterization of a busy general/pediatric dental operation with routine diagnostic throughput.

The practice shows limited activity on higher-complexity or less-common codes: D3330 (12 claims, $6.6K, ranks #2 of 2 at the 0th percentile) and D2160 (111 claims, $13.1K, ranks #7 of 7 at the 0th percentile) are low-volume relative to peers, indicating constrained involvement in complex endodontics or multi-surface restorative work compared with in-state colleagues. These low volumes imply the provider either refers higher-complexity cases elsewhere or focuses its case mix on preventive, diagnostic, simple restorative, and extraction procedures.

Tenure is long-standing: the NPI was enumerated on 2007-02-21 (~19 years ago), which combined with the established pattern of Medicaid billing suggests an entrenched local practice rather than a recent entrant. That longevity supports assumptions about stable patient flows and established referral or community ties.

From a risk and strategy perspective, the provider’s dependence on Medicaid and on a small set of high-revenue codes concentrates exposure: policy or rate changes affecting the top three revenue codes or shifts in Medicaid enrollment could materially affect revenue given that D4220, D7140, and D0150 together account for 47.3% of Medicaid receipts. Analysts should prioritize monitoring reimbursement rate trends and utilization rules for those codes when assessing financial or contract negotiations.
