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

Why is the Medicaid comparison limited to Arizona 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. Arizona (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 is effectively single-payer: lifetime Medicare revenue is $4M and there is no Medicaid billing on file, so Medicare activity drives the entire recorded public-payer footprint. This concentration means any analysis of scale, utilization, or peer comparisons should focus on Medicare only.

Revenue is extremely concentrated in a very small set of Medicare codes: the precomputed top-3 codes account for 99.7% of this provider’s total Medicare revenue. The three codes driving that share are Q4236 ($2.9M, 72.0%), Q4205 ($1.1M, 27.2%), and 15271 ($20.5K, 0.5%), indicating almost all Medicare dollars come from these line items.

The code mix and descriptions point to a wound-care / skin substitute business model rather than general primary-care throughput: Q4236 and Q4205 are per-square-centimeter skin substitute add-on codes (Carepatch and membrane graft/membrane wrap), and those two codes together account for nearly the full revenue base. High claim counts for product codes (Q4236: 3K claims, $973 avg paid/claim; Q4205: 938 claims, $1163 avg paid/claim) versus minimal E&M revenue indicate the practice operates primarily around supply and application of skin substitutes.

Competitive standing is mixed across the top codes. For Q4236 the provider ranks #20 of 79 nationally (76th percentile) and is characterized as having typical, unremarkable volume, meaning they are above median but not a dominant national leader; Q4205 ranks #34 of 63 (47th percentile) and is similarly described as typical, unremarkable volume, placing them near the middle of peers; 15271 ranks #105 of 1157 (91th percentile) and, while assigned a plain-English label of typical, unremarkable volume in the source, sits high in percentile rank relative to a large national peer set.

Payment-per-unit dynamics amplify the business picture: Q4205 commands the highest average payment per claim at $1163 while Q4236 averages $973 per claim, and 15271 averages $101 per claim. Together with claim volumes (Q4236: 3K claims; Q4205: 938 claims; 15271: 203 claims) this shows Q4236 drives the bulk of revenue through volume while Q4205 contributes meaningfully via a higher unit price.

Evaluation-and-management codes contribute negligible Medicare revenue relative to skin-substitute codes, underscoring the service-line focus. For example, 99214 appears with 98 claims and $7.9K revenue and 99204 with 13 claims and $1.3K revenue, indicating routine office visits are a minor component of the billed mix.

The provider’s NPI was enumerated on 2021-05-13 (~5 years ago), so this concentrated Medicare revenue profile has been established within a relatively recent practice tenure. The combination of rapid concentration into skin-substitute codes over about five years suggests a deliberate operational focus on that service line.

Because 99.7% of Medicare revenue is tied to three codes, the provider’s financial and operational performance is highly sensitive to changes in payer policy, code valuation, or supply-chain factors affecting skin substitutes. Analysts should treat reimbursement or policy shifts affecting Q4236, Q4205, or 15271 as high-impact to this provider’s topline given the observed concentration.
