CHOWDHURY AHSAN is a cardiovascular disease physician with an NPI enumerated on 2006-10-16, indicating roughly 20 years of Medicare/Medicaid billing tenure; this long enumeration supports experience delivering advanced cardiac imaging and monitoring services rather than a recent entrant model of care. The provider’s code mix is heavily weighted toward advanced cardiac imaging and stress testing services (PET myocardial perfusion codes 78492 and 78431, radiopharmaceutical codes A9555 and A9526, and stress testing codes 93015/93018).
Medicare revenue is the dominant payer for this profile: total Medicare revenue is $1.8M versus total Medicaid revenue of $64K, indicating the practice’s operations are overwhelmingly Medicare-driven and effectively single-payer in scale. This disparity suggests the provider’s case mix and reimbursement footprint are concentrated in an older population consistent with cardiovascular imaging and device monitoring.
Revenue concentration on Medicare is substantial: the precomputed top 3 Medicare codes by revenue account for 53.7% of Medicare revenue, signaling that a small set of advanced cardiac imaging services (notably PET perfusion and tracer dosing) drive over half of Medicare income. On the Medicaid side, the top 3 Medicaid codes account for 93.6% of Medicaid revenue, indicating Medicaid receipts are highly concentrated in a few routine diagnostic services (primarily 93010 and 93306).
The provider shows a national competitive footprint for several Medicare codes. For PET myocardial perfusion 78492 the provider ranks #42 of 926 (96th percentile) and for 78431 ranks #129 of 1377 (91st percentile), which together with high-volume radiopharmaceutical use (A9555 rank #59 of 1266, 95th percentile) indicates an above-typical national volume in PET cardiac imaging. Additionally, A9526 ranks #5 of 28 nationally (85th percentile) — a relatively high rank within a small peer set — reinforcing specialization in PET tracers. These ranks support characterization as a high-volume cardiac imaging center within national peer comparisons.
Several codes are statistical outliers or notably above typical national volume, reflecting operational emphasis. J2785 (regadenoson) ranks in the 99th percentile (#47 of 6388) and 93015 (exercise/medication stress test interpretation) is in the 99th percentile (#86 of 7716), both described as far above typical national volume. Routine ECG interpretation 93010 is an extreme outlier on Medicare (100th percentile, #153 of 50616) and also represents the largest share of Medicaid revenue (46.1% of Medicaid revenue, rank #22 of 209 in-state, 90th percentile), suggesting the provider performs very high volumes of ECG interpretation across payers.
Service-line implications: the mix of high-volume PET myocardial perfusion codes (78492, 78431), radiopharmaceutical dosing (A9555, A9526), stress imaging/supervision (93015) and ambulatory ECG monitoring/interpretation (93229, 93228, 93010) indicates the practice operates as an advanced cardiac imaging and diagnostic monitoring center, likely combining PET perfusion imaging, tracer administration, and rhythm monitoring as core offerings. The presence of both professional imaging codes and related device/monitoring codes (99490/99439/99457/) points to bundled longitudinal care and remote monitoring capabilities in addition to imaging.
Medicaid footprint is modest and concentrated in routine diagnostics: total Medicaid revenue is $64K with the top two Medicaid codes, 93010 and 93306, composing the bulk of that revenue (46.1% and 40.2% respectively). In-state ranks for these codes (93010 rank #22 of 209, 90th percentile; 93306 rank #55 of 174, 68th percentile) show the provider is a solid but not dominant state-level participant in ECG interpretation and transthoracic echocardiography for Medicaid patients. This suggests limited Medicaid volume relative to Medicare and a focus on basic diagnostic services for that payer.
Operational risk and capacity signals: the high concentration of Medicare revenue in a few imaging/tracer codes (top 3 = 53.7%) combined with extreme or notable percentile placements for several codes implies the provider depends on steady throughput of PET studies and associated tracers (A9555/A9526) and stress agents (J2785). Any changes in PET referral patterns, tracer access, or payer coverage for these services could materially affect revenue. Conversely, the broad use of remote monitoring and chronic care management codes (99490/99439/99457/99454) indicates diversification into longitudinal management that may partly mitigate imaging demand fluctuations.
