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.

How current is this data?

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

Key Findings

WAEL DAHHAN’s billing profile is consistent with a gastroenterology practice that performs endoscopic procedures and provides hospital-based evaluation and management: notable procedure codes include 45385 (40 claims, $193 avg paid/claim) and 45378 (15 claims, $147 avg paid/claim), while common E/M codes include 99222 (69 claims, $103 avg paid/claim) and 99232 (91 claims, $63 avg paid/claim). The presence of 43239 (35 claims, $84 avg paid/claim) further supports a mix of upper endoscopy biopsies and lower GI procedural work alongside inpatient consultations.

Revenue is tightly concentrated in a small set of Medicare codes: the precomputed top 3 Medicare codes by revenue account for 65.7% of this provider's total Medicare revenue, and the listed top three contributions are $7.7K (24.7%) from 45385, $7.1K (22.7%) from 99222, and $5.7K (18.3%) from 99232, out of total Medicare revenue of $31.3K. This concentration indicates that a few procedures and hospital E/M encounters drive most of the provider’s Medicare income.

Payer mix is effectively single-payer at this time: total Medicare revenue is $31.3K while the provider has no Medicaid billing on file. That absence of Medicaid activity means analyses and contracting considerations should treat the provider as Medicare-focused rather than mixed-payer.

Competitive standing by code is modest and largely “typical, unremarkable volume” relative to national peers: 45385 ranks #10000 of 16310 providers nationally (38th percentile; typical, unremarkable volume), indicating unremarkable colon polypectomy volume; by contrast 99222 ranks #19643 of 117621 (83th percentile; typical, unremarkable volume), showing relatively stronger placement for initial inpatient E/M. 99232 sits near the middle at #83884 of 177383 (52th percentile; typical, unremarkable volume), consistent with a modest national presence in subsequent inpatient visits.

Several commonly billed codes fall at low national percentiles despite being labeled typical, unremarkable volume: 43239 is at the 28th percentile, 45378 at the 25th percentile, 99223 at the 9th percentile, 99214 at the 4th percentile, and 45380 at the 2th percentile. These placements suggest lower-than-average Medicare volume for some biopsy, surveillance colonoscopy, high-level initial inpatient visits, and office E/M services relative to peers.

Provider tenure is established but not long-standing: the NPI was enumerated on 2016-05-28 (~10 years ago). Given roughly a decade of enrollment paired with $31.3K in Medicare revenue, the profile is consistent with a clinician who has a sustained but relatively small Medicare revenue footprint.

Average paid-per-claim patterns reflect a mix of procedure and E/M economics: 45385 averages $193 paid/claim, 99222 averages $103 paid/claim, and 99232 averages $63 paid/claim, indicating that higher-paid endoscopic procedures and lower-paid inpatient E/M visits both contribute materially to receipts. Operationally, this suggests the practice balances procedure revenue with hospital consultation time rather than relying solely on high-volume office visits.

From an operational and contracting perspective, the dominance of inpatient E/M codes (99222, 99232) together with key endoscopic procedures (45385, 43239) points to a practice oriented toward hospital-based care and procedural throughput; the lack of Medicaid billing further narrows the provider’s payer exposure. Analysts should therefore consider hospital privileging, on-call arrangements, and procedure capacity when benchmarking or engaging this provider.
