    Key Findings

    The provider’s Medicare lifetime revenue totals $929K and there is no Medicaid billing on file, which makes this practice effectively single-payer Medicare in scale and financial footprint within the available data. This payer concentration means analyses of utilization and risk should focus on Medicare ESRD payment patterns rather than Medicaid behavior for this NPI.

    Revenue is extremely concentrated in dialysis-related monthly management codes: the precomputed top-3 Medicare codes account for 98.6% of the provider’s total Medicare revenue. In particular, 90960 alone generates $842.6K (90.7% of Medicare revenue), indicating a narrow, highly specialized revenue base.

    Code-level activity confirms a dominant ESRD care operation: 90960 (3.1K claims, $276 avg paid/claim) and 90961 (292 claims, $228 avg paid/claim) are the two primary drivers of revenue, together making up the vast majority of receipts. The code descriptions for 90960 and 90961 — monthly ESRD management with multiple face-to-face visits — imply this provider’s volume reflects ongoing in-person dialysis management rather than occasional outpatient consults.

    Competitive standing on core ESRD codes is nationally prominent: the provider ranks #1 of 6549 providers nationally for 90960 (100th percentile; extreme outlier) and ranks #88 of 6091 providers for 90961 (99th percentile; extreme outlier). These rankings position the provider as an outlier well above typical national volume for ESRD monthly management.

    Non-ESRD office visit codes are minimal both in revenue and rank, underscoring the ESRD focus: 99213 accounts for $7.5K (0.8% of Medicare revenue) with 136 claims and ranks #144846 of 457151 providers nationally (68th percentile), a typical volume for general office visits. Other E/M codes such as 99214 and 99204 contribute only small fractions of revenue, signaling limited general outpatient clinic throughput.

    Service-mix implications for business operations are clear: the predominance of 90960 and 90961 suggests staffing, scheduling, and capacity are likely optimized for recurring, high-frequency ESRD encounters rather than episodic nephrology consults or broad multispecialty care. Billing mix and operational metrics (claims counts and average paid per claim for 90960 and 90961) support an ongoing, procedure-centric practice model.

    Tenure and geographic context: the provider’s NPI was enumerated on 2007-05-08 (~19 years ago) and is located in WAKE ISLAND, HI, indicating long-standing enrollment in Medicare which may reflect sustained ESRD service delivery over time. Longevity combined with the extreme outlier status on ESRD codes suggests an established local or niche operational footprint.

    From a risk and contracting perspective, the lack of Medicaid activity (none below — no Medicaid billing on file) combined with heavy Medicare concentration increases revenue vulnerability to Medicare policy or reimbursement changes specific to ESRD monthly management codes. Payers and network planners should treat this provider as a Medicare-driven ESRD specialist rather than a mixed-payer general nephrology provider.
