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 U.S. Virgin Islands for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to U.S. Virgin Islands 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. U.S. Virgin Islands (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

This provider is effectively single-payer in the available data: lifetime Medicare revenue is $27.2K and there is no Medicaid billing on file, indicating Medicare accounts for 100% of recorded public-payer activity and the provider does not appear in state Medicaid claims for the period covered. Analysts should treat any Medicaid comparisons as not applicable when assessing this provider's public-payer footprint.

Revenue is concentrated: the precomputed top 3 Medicare codes by revenue account for 73.6% of the provider's total Medicare revenue, signaling that a small set of outpatient E/M and care-management services are the primary revenue drivers for this practice. This concentration suggests business downside if utilization of those specific services declines.

The dominant Medicare services are office/office-outpatient E/M visits and chronic care management: 99213 ($8K, 29.6% of Medicare revenue), 99214 ($7.3K, 26.7%), and 99490 ($4.7K, 17.4%). Together these three codes imply the provider’s practice mix focuses on established outpatient visits across low-to-moderate complexity and monthly chronic care coordination rather than procedure-driven specialties.

Service-level detail supports a primary care / longitudinal care model: high volume of 99213 and 99214 visits combined with frequent 99490 chronic care management billing and point-of-care testing codes such as 83037 (HgbA1c) and 82962 (glucometer checks) indicate routine management of chronic conditions like diabetes in an outpatient setting. The presence of 36415 and 83037 further implies on-site specimen collection and diabetes monitoring are part of the care workflow.

Competitive standing on core codes is modest to typical rather than dominant: 99213 activity ranks at the 73th percentile nationally and is described as typical/unremarkable volume, 99214 is at the 53th percentile (typical), and 99490 sits near the mid-distribution at the 44th percentile among reporting providers. These percentiles suggest the provider operates at common volume levels for these services nationally rather than as a high-volume regional leader.

Tenure is long enough to establish patterns: the NPI was enumerated on 2016-09-09 (about 10 years ago), so the provider has had a stable Medicare billing identity for a decade, supporting interpretation of the observed code mix as an established operating pattern rather than a transient billing snapshot.

Unit economics are low-dollar, visit-driven payments: average paid per claim on the top E/M codes is relatively modest ($49 for 99213, $61 for 99214, $96 for 99215) and many high-frequency lab/monitoring codes pay in the single digits per claim (e.g., 83037 at $10, 36415 at $8, 82962 at $3). This mix points to a business model reliant on visit volume and recurring monthly care-management billing rather than high-margin procedures.

There are no pronounced statistical outliers among the top codes: the report labels the listed codes as typical or unremarkable volumes with percentiles generally in mid-to-high ranges (for example 83037 at the 91th percentile is higher than peers but still described as typical), so while some testing codes appear relatively frequent, overall the provider’s patterns align with mainstream practice-level utilization rather than exceptional deviation.
