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

Why is the Medicaid comparison limited to Missouri 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. Missouri (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’s Medicare footprint is concentrated but diversified across office visits, in-office injectables, and high-volume lab testing: total Medicare revenue is $1.3M with the top 3 Medicare codes (87798, 99214, J0897) accounting for 38.0% of this revenue. The mix includes high-volume NAAT-style lab work (87798 and many other amplified-probe codes), frequent established-patient E/M visits (99214), and substantial injectable billing (J0897), consistent with an office-based urology practice that combines procedural care, chronic management, and on-site specimen testing.

Revenue concentration is meaningful at the code level: 87798 generated $185.8K (16.5% of Medicare revenue), 99214 generated $132.2K (11.7%), and J0897 generated $111.3K (9.9%), and those three together represent the precomputed 38.0% share of Medicare revenue. This indicates that a relatively small set of services—laboratory NAAT testing, mid-level established-patient visits, and denosumab injections—drive more than a third of the provider’s Medicare income.

Payer mix is effectively single-payer Medicare: this provider reports $1.3M in total Medicare revenue and has no Medicaid billing on file. That absence of Medicaid activity suggests the provider’s population and revenue strategy are focused on Medicare beneficiaries rather than dual- or Medicaid-dominant panels.

Competitive standing shows a mix of local dominance and typical volumes: the provider is an extreme national outlier on 99214 (1.6K claims, ranks #2785 of 479517; 99th percentile, labeled “extreme outlier, far above typical national volume”) and also shows extreme outlier status on other E/M and new-patient codes such as 99204 (284 claims, $29.3K; 99th percentile). At the same time, many laboratory NAAT codes (for example, 87798) and commonly used urology procedures (52000, 52356) sit in high but more typical percentiles (e.g., 87798 at the 85th percentile; 52000 at the 96th percentile), indicating unusually high patient volume for office visits alongside broadly elevated but not exceptional lab/procedure throughput.

Several lab codes are notable for unusually high ranked volume versus peers: 84311 is ranked #2 of 72 providers (99th percentile; described as “notably above typical national volume”) and 84580 and 82010 are ranked #1 in their comparisons (both 100th percentile, with 82010 labeled “extreme outlier”). This cluster of top-ranked lab codes, together with many amplified-probe NAAT codes (e.g., 87491, 87591, 87640), points to a practice that either processes a large share of its own urine and infectious-disease testing or channels a high testing volume through its billing NPI.

The practice shows a strong emphasis on longitudinal chronic care management: 99490 appears with 2.3K claims and $101K revenue (8.9% of Medicare revenue) and 99439 also appears with 455 claims and $15.5K revenue (1.4%). High use of these chronic care codes, alongside frequent 99214 visits, suggests a significant panel of patients requiring ongoing coordination across multiple conditions rather than a purely procedure-driven caseload.

Procedural capacity is evident but not solely dominant: cystoscopy/ureteroscopy codes like 52000 (237 claims, $36K; 96th percentile) and 52356 (59 claims, $18.1K; 98th percentile and noted as “notably above typical national volume”) confirm that the provider performs endoscopic and stone-related procedures, supplementing the office-based E/M and injection services. The provider’s CPT mix therefore supports a hybrid model—regular in-office visits and injections complemented by periodic operative interventions.

NPI tenure indicates long-established billing activity: the NPI was enumerated on 2006-09-26 (~20 years ago), which aligns with a mature practice profile reflected in sustained Medicare billing across E/M, injectables, chronic care management, high-volume lab testing, and procedural codes. This longevity combined with the code-level concentration and select top-percentile ranks suggests an experienced, Medicare-focused urology practice with particular strengths in office-based management and in-house or closely affiliated laboratory services.
