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

Why is the Medicaid comparison limited to Louisiana 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. Louisiana (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

DR. MICHAEL GAMBILL AND DR. DAVID GLASS LLC is effectively a single-payer Medicaid provider: there is no Medicare billing on file and lifetime Medicaid revenue is $31M. The absence of Medicare activity makes Medicaid the sole material revenue stream for this practice and concentrates payor exposure to state pediatric dental programs.

Revenue concentration is high: the precomputed top 3 Medicaid codes account for 38.7% of the provider's total Medicaid revenue, indicating a reliance on a small set of services for a large share of income. The individual leaders among those top drivers are D2930 ($6.3M, 20.5% of Medicaid revenue), D1120 ($3.2M, 10.3%), and D0120 ($2.5M, 8.0%), which together form the bulk of billings.

The code mix and volumes identify a pediatric-focused preventive and restorative operation. High counts for preventive and routine-care codes — D1120 with 93.5K claims, D0120 with 91K claims, D1208 with 76.4K claims, and D1351 with 60.5K claims — show heavy throughput of prophylaxis, fluoride, and sealant services consistent with a high-volume pediatric dental clinic.

Competitive standing in-state is dominant across many codes: the provider ranks #1 in Louisiana for D2930 (rank #1 of 143, 100th percentile), D1120 (rank #1 of 610, 100th percentile), D0120 (rank #1 of 734, 100th percentile), D1351 (rank #1 of 231, 100th percentile), and multiple radiograph and fluoride codes. These rank and percentile signals are labeled as "extreme outlier" or similar in the source data, indicating volumes far above typical state peers.

The practice also performs substantial restorative and surgical work alongside prevention. Codes like D2392 ($1.4M revenue, ranks #2 of 404, 100th percentile), D2391 ($1M, ranks #2 of 296, 100th percentile), and D7140 (21.5K claims, $1.5M revenue, ranks #3 of 335, 99th percentile) demonstrate meaningful revenue from restorative composites and extractions in addition to preventive services.

Several high-revenue items are statistical outliers in the state, which has implications for network contracting and utilization review. Multiple top codes are explicitly flagged as "extreme outlier" or "notably above typical" and occupy top percentile ranks (many at the 100th percentile), so the provider represents an unusually large share of state Medicaid volume for those procedures.

Tenure and NPI history: the NPI was enumerated on 2015-05-13 (~11 years ago), giving the practice a multi-year footprint in the state Medicaid program. That tenure, combined with sustained high volumes across preventive and restorative pediatric codes, suggests an established operation rather than a short-term billing spike.

Operational implications for payers and networks include concentration risk and contracting leverage: with $31M in Medicaid revenue and top codes comprising 38.7% of that revenue, changes in Medicaid fee schedules, prior authorization policies, or access-management for pediatric dental codes could materially affect this provider's volumes and state-level capacity for pediatric dental care. Payers should note the practice's outsized role in delivering routine pediatric preventive care in Louisiana when modeling network adequacy and access metrics.
