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

Why is the Medicaid comparison limited to North 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. North 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.

Key Findings

DAVID SCHALL is an Orthopaedic Surgery Physician based in GRAND FORKS, ND with Medicare lifetime revenue of $268.1K and no Medicaid billing on file, making his practice effectively single‑payer (Medicare) in the available data. His NPI was enumerated 2006-01-27 (~20 years ago), indicating long-standing participation in Medicare that is consistent with an established surgical referral base.

Revenue is heavily concentrated in a small set of major codes: the precomputed top three Medicare codes (27447, 27130, 99213) account for 56.0% of this provider’s total Medicare revenue. In particular, 27447 alone represents 30.9% of Medicare revenue ($82.9K), while 27130 contributes 13.0% ($34.8K) and 99213 contributes 12.1% ($32.6K), signaling dependence on high-value joint replacement and routine outpatient evaluation services.

The code mix points to a surgical arthroplasty-centered practice with supporting office-based care and injections: high-revenue replacements 27447 (total knee arthroplasty) and 27130 (total hip arthroplasty) are the largest contributors, while frequent E/M codes (99213, 99214, 99203, 99204) and procedure codes for joint injections (20610) and hyaluronan injections (J7325) show integrated perioperative and nonoperative management. The presence of 20985 (computer assisted navigation) among top codes further supports that joint replacement is a core service line and that navigation technology is used in some cases.

Competitive standing by code is mixed: 27447 ranks #1344 of 12089 (89th percentile) and 99213 ranks #30657 of 457151 (93th percentile), both characterized as typical, unremarkable volume at those percentiles but above median; 27130 ranks #2602 of 8062 (67th percentile), closer to peer average. Overall, these rankings position the provider as a respectable regional arthroplasty operator rather than a national volume leader for hip or knee replacement.

There are notable statistical outliers in procedural volumes that speak to practice patterns: 20610 (arthrocentesis/injection without ultrasound) ranks #1331 of 39752 (97th percentile) and is labeled “notably above typical national volume,” indicating an unusually high rate of in-office joint procedures relative to peers. Even more extreme, J3301 (triamcinolone acetonide injections) ranks #251 of 38702 (99th percentile) and is labeled an “extreme outlier, far above typical national volume,” suggesting heavy reliance on corticosteroid injections in outpatient management.

Imaging and adjunct service volumes corroborate the surgical focus: knee X-ray 73564 appears with 198 claims and ranks in high percentiles for imaging volume, and 20985 (CANS) appears with 26 claims and $2.9K revenue, indicating use of intraoperative navigation for some joint replacements; these patterns are consistent with a practice performing a steady throughput of preoperative imaging and technology-assisted arthroplasty.

Payer mix and financial exposure are concentrated: with $268.1K in Medicare revenue and no Medicaid billing on file, the provider’s recorded revenue stream is effectively Medicare-dependent, which implies a senior-skewed patient panel in the available data and potential vulnerability to Medicare reimbursement changes. Analysts should treat the Medicaid absence as a clear differentiator from providers with mixed public-payer exposure, and verify commercial payer activity separately if assessing total practice revenue.

The long tenure (NPI enumerated 2006-01-27 (~20 years ago)) together with a code profile dominated by joint replacement and high-volume injections suggests operational stability and an established referral network for arthroplasty and related outpatient procedures, supporting the inference that these revenue drivers reflect deliberate, sustained service lines rather than transient activity.
