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

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

How current is this data?

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

Key Findings

DAVID ZAENGER is a radiation oncology physician enumerated NPI on 2012-06-24 (~14 years ago) with $2.3M in reported lifetime Medicare revenue and no Medicaid billing on file; this profile indicates a Medicare-dominant practice footprint in Myrtle Beach, SC with effectively single-payer reimbursement exposure.

Revenue is highly concentrated: the precomputed top three Medicare codes (G6015, 77014, and 77301) together account for 74.4% of this provider's total Medicare revenue. Individually those codes are reported as G6015 $1.1M (46.7%), 77014 $373.5K (16.2%), and 77301 $266.2K (11.6%), showing most income derives from a small set of radiation-delivery and planning services.

The code mix and descriptions point to a practice focused on high-volume external beam and advanced conformal therapies: G6015 (intensity modulated treatment delivery), 77301 (IMRT planning), 77336 and 77338 (medical physics/MLC planning), and 77427 (radiation therapy delivery) together imply substantial investment in IMRT planning, physics support, and daily treatment delivery. Presence of stereotactic codes 77373 and 77435 further indicates capability to deliver SBRT courses in addition to conventionally fractionated IMRT.

Operational throughput is notable: claim counts are very large for session-level codes (G6015 4.2K claims and 77014 4.3K claims), which along with high paid-per-claim values for planning codes (77301 $1,318 avg paid/claim) suggests a workflow centered on many treatment fractions supported by high-complexity planning. These claim volumes are far above typical national volumes for those CPT/HCPCS codes.

This provider ranks as a national outlier on multiple high-revenue codes, signaling dominant volume in specific services: G6015 ranks #15 of 1429 (99th percentile; extreme outlier), 77014 ranks #13 of 4303 (100th percentile; extreme outlier), and 77301 ranks #23 of 3815 (99th percentile; extreme outlier). Collectively these rankings indicate the provider is an unusually large generator of revenue for IMRT and treatment-delivery services compared with national peers.

Clinical-facing E/M activity is present but limited relative to procedural revenue: 99205 and 99204 appear in the top codes (92 and 108 claims respectively) but together account for a small share of Medicare revenue. By contrast, technical and physics codes (77336, 77338, 77300) account for measurable revenue and suggest integrated treatment planning and medical physics functions are core to the business model.

Payer mix is effectively single-payer Medicare: there is no Medicaid billing on file. That concentration means reimbursement performance and any Medicare policy or pricing changes could materially affect overall revenue, since Medicaid does not appear to provide a diversification buffer.

Given the repeated "extreme outlier" and "notably above typical" labels across core radiation codes, this provider should be treated as an unusually high-volume IMRT/SBRT operator when performing benchmarking, network contracting, or utilization reviews; contract negotiations and utilization-management strategies should account for concentrated revenue from a handful of high-volume, high-complexity radiation codes.
