This provider is effectively a wound-care–centric podiatry practice on Medicare: Q4217 (woundfix/biowound add-on per cm2) generates $4.6M in Medicare revenue and represents 97.4% of this provider's total Medicare revenue, indicating the practice bills extensively for area-based biologic/skin-substitute products or services. Companion skin-substitute codes 15275 and 15271 also appear on the Medicare list, reinforcing a service-line focused on advanced wound coverage and management rather than routine office visits or general podiatry procedures.
Medicare revenue is the dominant payer for this provider: total Medicare revenue is $4.7M versus total Medicaid revenue of $23.5K, showing Medicare-scale operations dominate this clinician’s billing footprint while Medicaid activity is minimal in comparison. This gap indicates the practice’s commercial/Medicare-facing business model supplies most of its billed services and revenue.
Revenue concentration is extreme on Medicare: the precomputed top 3 Medicare codes by revenue account for 98.9% of this provider's total Medicare revenue, which signals a very narrow set of procedures driving nearly all Medicare receipts. For Medicaid the precomputed top 3 codes account for 100.0% of the provider's total Medicaid revenue, showing Medicaid billing is likewise concentrated in a couple of code lines.
Competitive standing for the dominant Medicare code is high within its small national peer set: Q4217 ranks #9 of 65 providers nationally (88th percentile) and is described as "typical, unremarkable volume for this code," which positions the provider among the higher-volume national users of that product but still within the expected range for peers. By contrast, the Medicare E/M code 99213 ranks #13017 of 457151 providers nationally (97th percentile) and is labeled "notably above typical national volume," indicating this provider also bills office visits at a volume that is unusually high relative to the broad national pool.
State-level Medicaid activity is modest and concentrated: Medicaid 99213 contributes $20.1K (85.1% of Medicaid revenue) and ranks #722 of 1312 in-state (45th percentile), while Medicaid 11721 contributes $3.5K (14.9% of Medicaid revenue) and ranks #81 of 111 in-state (27th percentile). These Medicaid ranks and shares indicate routine office visits and multi-nail debridement are the only meaningful Medicaid services, and neither is a dominant outlier in the state peer set.
The broader CPT mix beyond the top wound and E/M codes includes procedure-level podiatry codes such as 11721 (nail debridement), 11042 (debridement to subcutaneous layer), and various debridement and nail-removal codes, which supports a hybrid clinical profile: concentrated advanced wound/skin-substitute billing plus a secondary set of typical podiatric procedures. The presence of both product-based add-on billing (Q4217) and service-level debridement codes suggests the practice integrates device/product use with hands-on wound care.
Tenure is long: the NPI was enumerated on 2006-02-01 (~20 years ago), indicating an established billing history and likely sustained clinical presence in GRINNELL, IA. This long enumeration combined with concentrated revenue lines suggests a stable practice model focused on wound-related interventions.
Statistical descriptors in the data are mixed: most high-revenue procedural codes are labeled "typical, unremarkable volume," but the Medicare 99213 E/M code is explicitly labeled "notably above typical national volume," pointing to an atypically high office-visit billing rate on Medicare relative to national peers. There are no labels here indicating extreme outlier behavior for the major wound-care code, so while Q4217 drives nearly all Medicare dollars, its usage falls within expected peer patterns for that specific code set.
