CMAT Advantage is HealthWright Technologies’ FDA-cleared comprehensive cardiovascular monitoring service built around the TM-Flow device. Unlike standard Ankle-Brachial Index (ABI) testing, which provides a single pressure ratio, CMAT Advantage performs a 7–10 minute, non-invasive workup that combines ABI, toe-brachial index (TBI), segmental blood pressure, volume plethysmography, heart rate variability (HRV), Ewing battery autonomic tests, sudomotor function, and galvanic skin response — producing a multi-system risk profile in one visit. For independent primary care, cardiology, and pain management practices, the difference affects diagnostic yield, reimbursement, and patient outcomes in peripheral arterial disease (PAD), diabetic autonomic neuropathy, and cardiovascular risk stratification.
What is the difference between CMAT Advantage and a standard ABI test?
A standard ABI test measures the ratio of systolic blood pressure at the ankle versus the arm and reports a single numeric value. CMAT Advantage includes ABI plus six additional measurements (TBI, segmental pressures, volume plethysmography, HRV, autonomic function, sudomotor screening) in the same 7–10 minute sitting. The result is a whole-vascular and autonomic snapshot rather than a single pressure ratio.
- Standard ABI: single pressure ratio, screens for PAD, limited in calcified vessels common in diabetes
- CMAT Advantage: ABI + TBI (reliable in calcified vessels) + autonomic + sudomotor + HRV
- Test time: ABI alone ~5 minutes; CMAT Advantage ~7–10 minutes
- Device: CMAT Advantage uses TM-Flow as the core device
Is CMAT Advantage reimbursed by Medicare?
Yes. The individual tests bundled within a CMAT Advantage exam are covered by Medicare and most commercial payers when performed for appropriate clinical indications. HealthWright Technologies reports an approximate total reimbursement of around $400 per complete CMAT Advantage exam, depending on the specific CPT codes billed and payer contracts. Physicians should verify current local coverage determinations with their Medicare Administrative Contractor and confirm medical necessity documentation before billing.
Which patients benefit most from CMAT Advantage testing?
CMAT Advantage is most clinically valuable for patients with risk factors for both macrovascular and microvascular disease, where a standard ABI alone would miss autonomic or small-vessel involvement.
- Patients with diabetes — often have calcified ankle arteries that falsely elevate ABI; TBI and sudomotor testing add accuracy
- Patients ≥65 with hypertension or dyslipidemia — cardiovascular risk stratification
- Patients reporting intermittent claudication or non-healing wounds — PAD workup
- Patients with unexplained syncope or orthostatic symptoms — autonomic assessment via HRV and Ewing tests
- Patients with suspected diabetic peripheral neuropathy — sudomotor and galvanic skin response screening
How does CMAT Advantage fit into an independent practice?
CMAT Advantage is delivered as a package: the TM-Flow device plus staff training, implementation support, billing guidance, and ongoing technical support. HealthWright Technologies has been serving independent physicians since 2000 and opened its own clinics in 2018 to test products in real practice. The service is designed so that a medical assistant can run the test in a dedicated exam room, with physician interpretation at the end of the visit. Practices typically use CMAT Advantage to add ancillary revenue while improving early detection of PAD and autonomic dysfunction.
What does a CMAT Advantage exam look like in practice?
A typical exam is 7–10 minutes of measurement time with the patient supine. Cuffs are placed on arms, thighs, calves, and ankles; sudomotor electrodes are attached to hands and feet; and the TM-Flow system automates the sequence. Results are uploaded to the CMAT Cloud Platform for review, long-term patient tracking, and integration with practice workflows. Reports are designed to be interpretable at the point of care, with flagged abnormal findings and reference ranges.
