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

Why is the Medicaid comparison limited to Tennessee 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. Tennessee (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 government-payer activity is effectively single-payer: total Medicare revenue is $2.7M and there is no Medicaid billing on file. Analysts should treat Medicare as the primary public-sector revenue source when modeling this provider’s government-payor exposure.

Revenue is highly concentrated in a small set of drug-administration codes: the top three Medicare codes (J9271, J0897, J1556) account for 67.6% of total Medicare revenue. In particular J9271 represents $1.2M or 46.2% of Medicare revenue, J0897 represents $385.6K (14.9%), and J1556 represents $168K (6.5%).

The code mix indicates an infusion- and biologic-focused specialty practice: J9271 (pembrolizumab), J0897 (denosumab) and multiple chemotherapy/infusion administration codes (96413, 96417, 96402, 96365, 96367) dominate the billing list, and routine monitoring labs (85025, 80053, 82378, 82728) appear alongside those drug and infusion codes. Together this pattern is consistent with an oncology/infusion clinic or specialty infusion service that administers high-cost biologics and monitors patients with labs.

Competitive standing is uneven across products: for J0897 the provider ranks at the 98th percentile nationally and is described as "notably above typical national volume," indicating unusually high denosumab activity; by contrast J9271, while generating $1.2M (46.2% of revenue), is characterized as "typical, unremarkable volume" at the 91th percentile. J1556 is a relatively small share of revenue and ranks at a lower percentile, described as "typical, unremarkable volume."

Several non-drug codes are statistical outliers and point to above-average outpatient throughput: 99213 and 99211 are flagged as "extreme outlier, far above typical national volume," and 96402 is also an "extreme outlier." Those labels—together with claim counts such as 99213 (1.1K claims, $72.6K revenue) and 99211 (1.2K claims, $19.4K revenue)—suggest the practice sees high volumes of outpatient visits and procedure-level chemotherapy/infusion activity relative to peers.

Operationally, the practice’s heavy reliance on high-cost infusible drugs (notably J9271 and J0897) makes a large share of Medicare revenue sensitive to shifts in drug utilization or reimbursement policies. Given that the top three codes supply 67.6% of Medicare revenue, changes affecting any of these products could materially affect revenue composition.

The provider has long tenure in the NPI registry—enumerated on 2005-10-06 (~21 years ago)—which supports the interpretation of an established specialty operation rather than a newly formed clinic. That longevity likely underpins the sustained infusion and visit volumes seen in the Medicare data.

In sum, this is a Medicare-centric, infusion-oriented specialty practice with concentrated revenue in a few biologic drug codes (J9271, J0897, J1556) and unusual outpatient encounter and chemotherapy administration volumes relative to national peers; analysts should treat denosumab (J0897) and several infusion/visit codes as the provider’s strongest competitive signals while recognizing the business is sensitive to biologic drug reimbursement and utilization shifts.
