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

Why is the Medicaid comparison limited to South Dakota 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. South Dakota (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.

The Medicare and Medicaid tables are both single current snapshots, not refreshed on a recurring schedule yet.

Key Findings

MICHELLE DAFFER is a dermatology physician with a long-tenured Medicare enrollment, having been enumerated/registered since 2006-02-24 (~20 years ago), which indicates an established practice footprint in Dakota Dunes, SD and sustained participation in Medicare billing over multiple care cycles.

This provider’s Medicare revenue totals $362.4K while there is no Medicaid billing on file, making the practice effectively single-payer in the available data and reliant on Medicare as its primary public source of reimbursed activity.

Revenue concentration in Medicare is high: the precomputed top 3 Medicare codes by revenue account for 58.6% of the provider's total Medicare revenue, indicating that a small set of services — principally office visits and lesion treatments/surgeries — drive the majority of billings.

Office visit code 99213 is the single largest revenue contributor at $95.8K (26.7% of Medicare revenue) and this provider is an extreme outlier nationally for volume on that code (ranks #1858 of 457151, 100th percentile). This suggests a very high throughput of routine established-patient visits relative to peers, consistent with a busy clinic model focused on ambulatory dermatologic management.

Surgical and procedural dermatology is also a major service line: Mohs-related codes 17311, 17312, and 17313 together appear among the top revenue contributors (17311 alone accounts for $75.5K or 21.0% of Medicare revenue), but the provider’s national rank for 17311 (rank #1841 of 2969, 38th percentile) is middling, indicating typical Mohs procedural volume compared with the narrower national Mohs specialty cohort rather than dominance.

High-volume lesion destruction and biopsy codes are prominent operationally: 17000 ($39K, 10.9%) and add-on 17003 ($20.9K, 5.8%) are notably above typical national volume (96th and 97th percentiles respectively), and 11102 (100 claims, $6.8K) and 11103 appear in the top codes. Together these codes point to a substantial practice emphasis on managing premalignant and benign lesions with frequent destruction and biopsy workflows.

The provider’s procedural mix includes both higher-complexity excisions (e.g., 11603, 11602) and a range of wound-repair codes (12032, 12011, 12002, 12051, 12052), which suggests the practice performs surgical excisions and intermediate/simple repairs across anatomic sites. Most of these surgical and repair codes fall at typical or modest national percentiles, supporting a competent surgical practice without outsized national specialization outside of the high-volume office visits and lesion-destruction add-ons.

Competitive standing is mixed by code: for some high-volume general dermatology codes (99213, 17000, 17003) the provider ranks at or above the national 90th+ percentiles indicating very high throughput compared to general dermatology peers, while for specialty Mohs codes and several excision/repair codes the provider’s percentiles are largely in the middle or lower ranges, implying the provider is not a national leader in Mohs volume but retains a robust procedural caseload locally.
