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

Why is the Medicaid comparison limited to Colorado 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. Colorado (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 reported Medicare footprint is concentrated and material: total Medicare revenue is $1.9M while there is no Medicaid billing on file, so the practice is effectively single-payer (Medicare) in the datasets available. The absence of any Medicaid claims suggests limited participation in state programs or a payer mix focused on Medicare fee-for-service.

Revenue concentration is extreme by line-item: the precomputed top-3 Medicare codes account for 100.0% of this provider’s total Medicare revenue, and a single code, Q4253, represents $1.9M in revenue and 98.6% of the provider’s Medicare receipts. This indicates the provider’s Medicare billing is almost entirely driven by one add-on product/service rather than a broad mix of evaluation-and-management or procedure codes.

The code mix indicates a procedure/product-focused operation: Q4253 is an add-on for Zenith amniotic membrane billed per square centimeter, which typically accompanies a primary procedural service. The next-highest Medicare contributors are E/M nursing-facility visit codes (99309 with $22.3K and 99310 with $4.4K), reflecting occasional facility-based follow-up or post-procedure care but comprising only a small share of revenue relative to the amniotic-membrane activity.

Competitive standing on the primary revenue driver is modest at a national level: Q4253 ranks #18 of 73 providers nationally (76th percentile) and is described as "typical, unremarkable volume". That rank places the provider above many peers but does not indicate dominance in this code nationally; the provider appears to be a meaningful but not market-leading user of this add-on.

The secondary E/M codes show typical, low-to-moderate engagement with nursing-facility care. 99309 ranks #9718 of 28092 (65th percentile) and 99310 ranks #7326 of 12486 (41th percentile), both labeled "typical, unremarkable volume," while 99316 is reported at #6383 of 6630 (0th percentile) and also described as typical; collectively these ranks suggest routine, modest volumes rather than specialization in long-term care services.

Operational and revenue-risk implications are material given the dependence on a single add-on code: because Q4253 accounts for 98.6% of Medicare revenue, changes in reimbursement policy, coverage rules, or product availability for that specific amniotic membrane could disproportionately impact overall revenue. From a contracting and audit-monitoring perspective, this concentration is an important signal for payers and partners evaluating revenue sustainability.

Tenure in the NPI file is relatively recent: the NPI was enumerated on 2021-03-15 (~5 years ago). A practice with roughly five years of enumeration generating $1.9M in Medicare revenue concentrated in a single procedural add-on suggests either a focused specialty practice that adopted this product early or a high utilization pattern of the add-on in a narrow set of procedures during a relatively short operational window.
