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

Why is the Medicaid comparison limited to New Hampshire 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. New Hampshire (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 activity is concentrated in classic urology office care, endoscopic bladder procedures, and prostate-directed pharmacotherapy: the top three Medicare codes are 99214 ($104K, 29.8%), 52000 ($49K, 14.0%), and J9217 ($42K, 12.0%), which together account for 55.8% of Total Medicare revenue. Those codes point to a practice mix centered on evaluation & management visits, diagnostic/therapeutic cystoscopy, and leuprolide administration for prostate disease.

Revenue is almost entirely Medicare-driven: Total Medicare revenue is $364.3K while Medicaid shows none (no Medicaid billing on file), making this provider effectively single‑payer Medicare in scale. This concentration means analyses of payer mix, reimbursement risk, or network negotiations should treat Medicare as the dominant — and effectively sole — public payer exposure.

99214 is a clear national outlier for this provider: it generates $104K (29.8% of Medicare revenue) and the provider ranks in the 98th percentile nationally and is labeled an "extreme outlier, far above typical national volume for this code." By contrast 52000 and J9217 also rank high nationally (52000 at the 97th percentile, J9217 at the 92th percentile) but are described as typical/unremarkable volumes for those codes, indicating unusually high office E/M volume alongside otherwise expected procedural volumes.

Several other codes show above‑typical national standing for this provider and suggest additional clinic services. For example, 99204 ($21.7K, 6.2%) ranks in the 97th percentile and is described as "notably above typical national volume for this code," and 96402 ($3.7K, 1.1%) ranks in the 93th percentile and is also "notably above typical national volume," indicating meaningful new‑patient and therapeutic injection activity beyond routine follow‑ups.

The procedure and device mix indicates that the practice performs both endoscopic urologic procedures and implantable-device work: 52000 ($49K, 14.0%) and 52356 ($6.8K, 2.0%) reflect cystoscopy and ureteroscopy/lithotripsy services, while 64561 ($17.4K, 5.0%) and 64581 ($5.6K, 1.6%) represent sacral nerve neurostimulation electrode implants. These codes and their revenue shares suggest the provider operates with access to procedural/OR or ambulatory surgical resources and offers therapies for BPH, stone disease, and pelvic floor indications.

The drug and infusion claims profile shows a mix of high‑unit, low‑paid oncology/urology injectables and depot hormonal therapy: J9217 (leuprolide) contributes $42K (12.0%) and J9155 (degarelix) shows 3K claims but only $8.9K (2.5%) in revenue with a $3 avg paid/claim. That pattern signals routine administration of prostate cancer hormonal agents and high‑frequency, low‑unit billing for certain injectables rather than large single‑event chemotherapy billing.

Office diagnostic and monitoring services are notable but not dominant: PSA testing (84153) produced $5.2K (1.5%) on 287 claims, transrectal ultrasound (76872) produced $8.6K (2.5%) on 77 claims, and urine culture (87086) produced $1.9K (0.6%) on 243 claims. Together these findings reinforce a practice model centered on longitudinal urologic surveillance and outpatient diagnostic workups accompanying the higher‑revenue procedures and E/M visits.

This provider has long tenure in the Medicare program, with NPI enumerated 2006-08-31 (~20 years ago), which, combined with the concentrated code mix and sustained E/M volume, suggests an established urology practice with steady Medicare utilization patterns rather than a newly emergent billing profile. Analysts should interpret unusual code concentrations (especially the extreme 99214 volume) in the context of long standing practice patterns and limited Medicaid exposure.
