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

Why is the Medicaid comparison limited to Michigan 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. Michigan (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.

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

Key Findings

Service-line profile: STEVEN KATZMAN’s Medicare billing is concentrated in chronic care management and psychiatric collaborative care management services, driven by large volumes of codes that target clinical staff time and CoCM activities (notably 99489, 99487, 99493, 99494 and related codes). The mix of high-volume care-management codes alongside inpatient E/M codes (99232, 99233, 99223) indicates an operational model that pairs longitudinal care coordination for complex chronic and behavioral health needs with episodic inpatient follow-up.

Revenue concentration: The top 3 Medicare codes (99489, 99487, 99493) together account for 62.5% of this provider’s total Medicare revenue, demonstrating a high revenue concentration in care-management and collaborative psychiatric services rather than a broad procedural mix. Within that group, 99489 is 25.4% of Medicare revenue, 99487 is 24.6%, and 99493 is 12.5%, making these the dominant revenue drivers.

Competitive standing for top codes: Katzman ranks as a national outlier on multiple care-management and CoCM codes — 99489 ranks #18 of 1836 (99th percentile, extreme outlier), 99487 ranks #8 of 2701 (100th percentile, extreme outlier), and 99493 ranks #4 of 329 (99th percentile, extreme outlier). These rankings indicate a nationally dominant position specifically in reporting intensive clinical staff–directed care and collaborative psychiatric care relative to peers.

Additional outlier signals within care-management: Beyond the top three, 99494 ranks #1 of 159 providers nationally (100th percentile; extreme outlier), reinforcing that Katzman’s practice reports unusually high utilization of extended psychiatric care-management add-on time compared with the national provider set. At the same time, several other CCM codes such as 99490 and 99439 are at high percentiles (99th and 97th respectively) but are described as typical in volume, suggesting breadth in care-management activity as well as exceptional intensity for certain CoCM services.

Payer mix and single‑payer exposure: Lifetime Medicare revenue is $1.5M while there is no Medicaid billing on file, so this provider’s documented payer exposure is effectively single-payer Medicare at the present-recorded scale. That concentration implies the business is heavily dependent on Medicare reimbursement patterns and any policy or coding changes affecting chronic care management or CoCM would have outsized impact on revenue.

Inpatient and office E/M activity: Katzman also bills inpatient/observation E/M services (99232, 99233, 99223) and office visits (99213, 99214), with 99232 and 99223 both described as notably above typical national volume and 99213 also notably above typical, suggesting regular hospital-based follow-up and some higher-acuity inpatient work alongside outpatient management. The presence of both inpatient and longitudinal management codes supports a care-delivery model that spans hospital and ambulatory settings for complex patients.

Ancillary services and diagnostics are modest: Imaging and procedure lines (93306 echocardiography, 93880 vascular duplex, 93970 venous duplex, 76700 abdominal ultrasound) and routine services (36415 blood draw, 90662 flu vaccine) contribute relatively small shares of Medicare revenue and generally rank in lower percentiles or are described as typical. This pattern indicates Katzman’s practice performs some on-site diagnostics but that diagnostic procedures are not primary revenue drivers compared with care-management and CoCM services.

Tenure and billing history: The provider’s NPI was enumerated on 2006-08-21 (~20 years ago), indicating a long-standing billing presence in Medicare data. That tenure, combined with concentrated high-volume billing in specialized care-management codes, suggests an established practice or sustained programmatic focus on chronic and behavioral health management over many years.
