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

Why is the Medicaid comparison limited to Ohio 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. Ohio (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

CHRISTOPHER RIEMANN is an Ophthalmology Physician in CINCINNATI, OH with total Medicare revenue of $1.8M and no Medicaid billing on file, making his practice effectively single‑payer Medicare for the data available. His NPI was enumerated on 2005-10-17 (~21 years ago), indicating long tenure and an established billing history in Medicare programs.

Revenue concentration is high: the precomputed top 3 Medicare codes (J0178, J2777, J0179) account for 74.0% of this provider's total Medicare revenue. Those three codes individually generate $759.2K (42.4%), $382.8K (21.4%), and $182.3K (10.2%) respectively, indicating most revenue is driven by a small set of injection drug codes.

The service mix is dominated by intravitreal pharmacotherapy and retina diagnostics: J0178 (aflibercept) and J2777 (faricimab) are the top two revenue drivers and 67028 (intravitreal injection) also contributes $100.5K (5.6%), which together suggest a practice focused on repeated anti‑VEGF and related biologic injections. High utilization of retinal imaging is supported by 92134 (retinal OCT) at 1.5K claims and $43.3K (2.4%), implying integrated diagnostic imaging to support the injection-heavy service line.

Competitive standing by code is mixed: for the largest revenue driver J0178 the provider ranks #1175 of 3204 (63th percentile) and for J2777 ranks #788 of 2039 (61th percentile), both characterized as "typical, unremarkable volume," so his anti‑VEGF activity is within a common national range. By contrast, J0179 (brolucizumab) shows a comparatively high position at rank #11 of 64 (84th percentile), indicating he is a relatively prominent prescriber of that specific drug within a smaller national cohort.

There are notable deviations in diagnostic and unclassified code usage: 92134 is at the 95th percentile and described as "notably above typical national volume," which signals above‑average OCT utilization compared with peers and supports the inference of an imaging‑heavy workflow for retina care. Conversely, J3490 (unclassified drugs) sits at the 12th percentile for revenue contribution despite $42.4K (2.4%) reported, indicating that this unclassified drug billing pattern is low relative to the national set.

The provider performs some complex retinal surgical procedures but at low frequency: 67113 (complex retinal repair) shows 23 claims generating $21.9K (1.2%), and vitrectomy codes such as 67042 and 67036 together add smaller surgical revenue ($19.1K and $12.4K respectively, each ~1.1%–0.7%). These counts (e.g., 22–23 claims for major surgeries) suggest that surgical retina work is a secondary component of the practice compared with high-volume injection therapy.

Payer mix implications are straightforward: with $1.8M in Medicare revenue and "none below" for Medicaid, the provider is effectively single‑payer Medicare in the available dataset, which concentrates reimbursement and utilization risk on Medicare policies and coverage decisions. This alignment matters for payers and networks evaluating contracting or care management, since there is little Medicaid activity to diversify the payer base.
