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 Northern Mariana Islands for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to Northern Mariana 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. Northern Mariana 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 a small Medicare-focused biller: Total Medicare revenue is $21.9K while Total Medicaid revenue is none (no Medicaid billing on file), so public-payer activity is effectively single-payer (Medicare) rather than dual-payer. Analysts should not expect Medicaid claims data for in-state comparisons or volume.

Revenue is highly concentrated in a narrow set of inpatient E/M services — the precomputed top 3 Medicare codes by revenue account for 88.1% of this provider's total Medicare revenue. That concentration indicates a reliance on a few procedure types for the bulk of billed Medicare dollars.

The code mix and taxonomy point to an inpatient-focused internal medicine practice: the top codes are 99232, 99233, and 99239 (subsequent hospital inpatient care, higher-complexity subsequent inpatient care, and discharge day management). Combined with the provider taxonomy of Internal Medicine Physician, this pattern is consistent with hospital rounding or inpatient consult activity rather than office-based primary care.

Specific revenue contributions are concentrated in 99232 ($10K revenue, 45.4% of total Medicare revenue), 99233 ($5.5K revenue, 24.9% of total Medicare revenue), and 99239 ($3.9K revenue, 17.8% of total Medicare revenue). These three codes together represent the dominant sources of Medicare dollars for this provider and explain most of the $21.9K Medicare footprint.

Competitive standing across these codes is modest: 99232 ranks #57066 of 177383 providers nationally (68th percentile) and appears somewhat above median but not high-volume, while 99233 (rank #78982 of 128818, 38th percentile) and 99239 (rank #36798 of 62398, 40th percentile) both fall below the national median for their codes and are described as typical or unremarkable volumes. In aggregate, the provider is not a dominant national player for these inpatient E/M services.

Claim counts and per-claim payments underline the operational mix: 99232 has 158 claims with a $63 avg paid/claim, 99233 has 57 claims with a $96 avg paid/claim, and 99239 has 42 claims with a $93 avg paid/claim. This suggests a high frequency of lower-dollar subsequent inpatient visits supplemented by smaller numbers of higher-paid, more complex inpatient encounters and discharge management services.

NPI tenure is relatively recent: the provider enumerated on 2017-03-17 (~9 years ago). That length of activity is sufficient to observe a stable recent pattern but may limit long-term trend analysis compared with much longer-tenured peers.

For payers and network planners, the combination of low overall Medicare revenue ($21.9K), high concentration in three inpatient E/M codes (88.1%), and no Medicaid billing (none (no Medicaid billing on file)) signals a small, hospital-centered Medicare provider whose impact on broad population risk or Medicaid network capacity is minimal. Contracting or utilization review efforts should therefore focus on inpatient E/M patterns rather than ambulatory or Medicaid activity.
