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.

Key Findings

The provider’s Medicare revenue is tightly concentrated in inpatient evaluation-and-management services: 99232, 99233, and 99239 together account for 97.8% of total Medicare revenue, with reported revenue of $16.2K (99232), $11.4K (99233), and $5.7K (99239). These codes reflect subsequent hospital inpatient/observation care and discharge day management, indicating the practice’s revenue is driven overwhelmingly by inpatient follow-up and discharge encounters rather than outpatient primary-care office visits.

Overall scale is small and essentially single-payer: total Medicare revenue is $34K and there is no Medicaid billing on file (none below). This makes the provider effectively a Medicare-only biller in the dataset rather than a mixed Medicaid/Medicare practice, which limits conclusions about Medicaid-market activity or state-level payer strategy.

Claim volumes and average payments underline an operational emphasis on frequent, moderate-complexity inpatient follow-ups: 99232 shows 305 claims at $53 avg paid/claim, while higher-intensity subsequent visits 99233 show 139 claims at $82 avg paid/claim and 99239 shows 72 claims at $79 avg paid/claim. The mix of high claim count for 99232 with higher per-claim payments for 99233/99239 is consistent with a workflow handling many routine inpatient follow-ups plus a meaningful share of higher-complexity and discharge-management encounters.

Competitive standing against national Medicare peers is modest and characterized as typical for these codes: 99232 ranks #30035 of 177383 providers nationally (83th percentile; typical, unremarkable volume for this code), 99233 ranks #44532 of 128818 providers nationally (65th percentile; typical, unremarkable volume for this code), and 99239 ranks #26081 of 62398 providers nationally (58th percentile; typical, unremarkable volume for this code). Those percentiles and labels indicate the provider is not a dominant national player on these codes but operates at a routine volume level compared with peers.

There is a small, peripheral dialysis-related billing signal: 90935 appears with 16 claims, $46 avg paid/claim and $736 revenue (2.2% of total Medicare revenue), and it ranks #5836 of 6114 providers nationally (4th percentile; typical, unremarkable volume for this code). That placement and minimal revenue share suggest occasional dialysis-related services rather than a substantive dialysis practice line.

Tenure in the Medicare program is established but not long-standing: NPI enumerated on 2018-07-10 (~8 years ago). Given the small lifetime Medicare revenue ($34K) over that period, the data suggest a relatively low-volume Medicare practice operating consistently since enumeration rather than a recent surge in billing.

Geographic and setting implications align with inpatient activity in HAGATNA, GU: the dominant codes (99232, 99233, 99239) are tied to hospital inpatient/observation care and discharge management, implying the provider’s work is centered on hospital-based services in GU rather than ambulatory clinic-based primary care. The absence of Medicaid billing on file further reduces visibility into community outpatient volumes and suggests payer exposure is concentrated in Medicare hospital work.

Revenue concentration creates operational risk if inpatient referrals change: with 97.8% of Medicare revenue coming from three inpatient E/M codes, any decline in hospital inpatient/observation encounters or changes to inpatient care patterns would materially affect this provider’s Medicare revenue base. Monitoring hospital partnerships, inpatient census, and code-level utilization over time will be important for assessing sustainability of current billing patterns.
