    Key Findings

    Provider profile and tenure: JAN KRAEMER is a Pain Medicine (Anesthesiology) Physician enumerated on 2006-06-18 (~20 years ago), indicating long-standing Medicare enrollment and likely sustained clinical activity in interventional pain management over an extended period. The specialty and tenure support an expectation of procedural practice rather than a recent entrant or short-term billing pattern.

    Payer mix and scale: Lifetime Medicare revenue is $108.1K while Medicaid revenue is none (no Medicaid billing on file), making this effectively a Medicare-only billing profile for state/federal public programs. For analysts, this means competitive and utilization comparisons should focus on Medicare performance and national benchmarking rather than state Medicaid patterns.

    Revenue concentration: The top three Medicare codes — 64483, 64484, and 64635 — account for 69.5% of this provider's total Medicare revenue, signaling heavy concentration in a small set of interventional spine procedures. Specifically, 64483 returned $36.4K (33.6%), 64484 returned $19.5K (18.0%), and 64635 returned $19.3K (17.9%), which together drive the majority of billed Medicare dollars.

    Service-line implications: The code mix is centered on spine-focused interventional procedures (transforaminal epidural injections and facet joint neurolysis), showing a procedural, intervention-heavy practice rather than an office-based E/M model. Office E/M appears subordinate to procedures — e.g., 99203 produced $2.8K (2.6% of Medicare revenue) across 42 claims — consistent with a practice focused on image-guided injections and neurolytic treatments.

    Competitive standing by code: 64484 is a standout, ranking #125 of 4245 providers nationally and labeled "notably above typical national volume," indicating this provider’s unusually high use of the additional-level transforaminal injection relative to peers. By contrast, 64483 (rank #956 of 8202; 88th percentile) and 64635 (rank #1167 of 5957; 80th percentile) are described as "typical, unremarkable volume," so the overall national footprint is mixed — one notably above-typical code amid otherwise modest-to-typical participation.

    Claim-level mix and reimbursement snapshot: The provider reports 219 claims each for 64483 and 64484 with avg paid/claim of $166 and $89 respectively, and 77 claims for 64635 with avg paid/claim of $251, reflecting a blend of higher-volume, lower-paid add-on injection work and lower-volume, higher-paid neurolytic procedures. This combination suggests operational focus on repeatable injection visits supplemented by more resource-intensive neurolysis sessions, which together shape revenue and capacity planning.

    Analytic priorities and monitoring: Given the high revenue concentration in three interventional codes (69.5% of Medicare revenue) and absence of Medicaid billing, analysts should prioritize longitudinal monitoring of volumes for 64484 in particular (the notably above-typical code) and watch for shifts in the mix between transforaminal injections and neurolytic procedures. Comparative work should emphasize national-code-level percentiles and per-claim payments to detect changes in practice intensity, referral patterns, or shifts into other payers; absence of Medicaid activity also suggests limited exposure to state-managed care networks.
