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

Why is the Medicaid comparison limited to Montana 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. Montana (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 billing profile is centered on in‑office biologic and infusion therapy consistent with the Rheumatology Physician taxonomy; the top three Medicare J‑codes are J0129 ($203.2K, 30.0%), J3262 ($195.8K, 28.9%), and J1602 ($146.8K, 21.7%), and those three drugs together account for 80.6% of the provider’s total Medicare revenue. The dominance of high‑cost injectable biologic codes implies the practice’s primary service line is administration and management of infused/subcutaneously delivered biologic agents for chronic inflammatory disease rather than a visit‑only model.

Revenue is highly concentrated in a small set of biologic drugs: the precomputed top‑3 share is 80.6% of Medicare revenue, and the total Medicare revenue on file is $656.8K. That level of concentration means the practice’s financial performance is tightly linked to utilization and reimbursement of a handful of J‑codes rather than broad office‑based E/M income or ancillary services.

Payer mix is effectively mono‑payer at the claim level: Medicare revenue is $656.8K while there is no Medicaid billing on file. This absence of any Medicaid activity makes the provider operationally dependent on Medicare beneficiaries and commercial/other payers not represented here, which is a single‑payer exposure from the public program perspective.

On competitive standing for the three revenue drivers, the provider is a modest participant nationally rather than a dominant provider: J0129 ranks #817 of 1221 providers nationally (33th percentile; typical, unremarkable volume), J3262 ranks #311 of 618 (50th percentile; typical, unremarkable volume), and J1602 ranks #519 of 1041 (50th percentile; typical, unremarkable volume). These rank positions indicate routine to middling market share on these specific biologics rather than leadership in volume.

Clinical complexity and office visit intensity are notable: 99215 appears with 335 claims and $42.5K (6.3% of Medicare revenue) and ranks #4649 of 145531 providers nationally (97th percentile; notably above typical national volume), while 99214 contributes $36.8K (5.4%) and ranks in the 86th percentile. Together, the elevated percentiles for high‑level E/M codes support that the practice manages complex, high‑decision‑making follow‑up care for patients receiving advanced therapies.

Infusion and administration services are an active element of operations: 96365 shows 306 claims and $15.6K (2.3% of Medicare revenue) and ranks in the 89th percentile, indicating above‑typical provision of initial IV infusion services compared with national peers. Presence of chemotherapy/infusion‑related codes such as 96413 ($5.8K, 0.9%) and add‑on infusion time code 96415 ($1.9K, 0.3%) further supports routine use of in‑office infusion capacity, even though those codes represent smaller revenue shares.

Ancillary therapeutic and preventive items contribute only modestly to revenue: codes such as J0897 (denosumab, $19.4K, 2.9%), 90662 (flu vaccine, $852, 0.1%), and G0008 (influenza administration, $403, 0.1%) are present but account for small slices of total Medicare revenue. This pattern indicates the practice’s ancillary services are secondary to its core biologic infusion business rather than a major separate revenue stream.

The provider has a long tenure in the Medicare program, with the NPI enumerated on 2006‑05‑26 (~20 years ago), signaling an established clinical presence. Combined with the high share of biologic J‑codes and elevated high‑level E/M activity, the data depict an experienced rheumatology practice focused on management of complex chronic inflammatory conditions via biologic therapies.
