The Business Case for Physicians: Adding TM-Flow Testing to Independent Clinics

For independent physicians, adding TM-Flow testing turns a single 7 to 10 minute, non-invasive visit into three billable diagnostic assessments—ankle-brachial index with pulse-volume recording (ABI + PVR), autonomic nervous-system analysis, and sudomotor testing. Distributed by HealthWright Technologies, the system is built on FDA-cleared component devices, pairs with a structured partnership and training program, and helps practices evaluate peripheral arterial disease (PAD) and autonomic dysfunction earlier while supporting documented, reimbursable in-office diagnostics. The sections below break down the clinical case, the reimbursement math, and how the workflow fits a busy independent practice.

Want the code-level detail? Our breakdown of how a single TM-Flow visit supports three stacked CPT codes shows exactly how PAD and autonomic testing combine into one efficient, reimbursable workflow.

1 | Why Expand Beyond Traditional PAD Testing?

• Missed Disease – Manual Doppler ABI alone can under-detect PAD in diabetics and patients with calcified vessels.
  
• Value-Based Care Pressures – Payers expect objective documentation and measurable outcomes, yet reimburse for validated non-invasive tests.
  
• Diagnostic Services Gap – Independent clinics often miss opportunities to characterize conditions objectively through in-office diagnostic testing.
  

TM-Flow, distributed by HealthWright Technologies Inc, addresses all three by delivering three diagnostic assessments—ABI + PVR, autonomic nervous-system (ANS) analysis, and sudomotor testing—in a single 7 to 10 minute session.

2 | What Are the Clinical and Operational Advantages of the TM-Flow System?

3 | How Much Revenue Can a Practice Generate at 10 Tests per Week?

A code is billable only when the matching test was medically necessary for a symptomatic or at-risk patient and that necessity is documented; whether a plan pays, and how much, varies.

4 | How Does TM-Flow Testing Fit Into the Clinic Workflow?

1. Identify Candidates – EHR flags high-risk patients (DM, smokers, age > 65).
2. Prep & Attach – MA places simultaneous arm/ankle cuffs and two skin pads.
3. Auto-Run Test – Device captures ABI, PVR, HRV, and sudomotor data in one pass.
4. Instant Report – Color-coded PDF saved to the patient’s chart; physician reviews in-visit.
5. Bill & Document – Pre-filled superbill with three CPTs; attach report as backup.
6. Recall & Follow-Up – Automated reminders support ongoing monitoring of patients whose findings warrant follow-up.
   

Average added chair-time: ≈ 3 minutes beyond routine vitals.

Frequently Asked Questions

Is the TM-Flow System FDA-approved or FDA-cleared?

The TM-Flow System is FDA-cleared through the 510(k) pathway, not FDA-approved. FDA clearance applies to Class II devices that demonstrate substantial equivalence to a legally marketed predicate device; FDA approval (PMA) is a separate, higher-bar pathway for Class III devices. Using “FDA-cleared” is the accurate term for this device in all clinical and marketing materials.

Which CPT codes does TM-Flow testing support?

A complete TM-Flow session can support up to three CPT codes when medically indicated and documented: 93923 (ABI / pulse-volume recording), 95921 (autonomic nervous-system function testing), and 95923 (sudomotor / autonomic testing). Coverage and reimbursement vary by payer and region—always verify coverage and documentation requirements with each plan. See our guide to the ankle-brachial index CPT codes for detail.

How long does the test take and who can perform it?

A full assessment runs about 7 to 10 minutes and adds roughly three minutes of chair-time beyond routine vitals once staff are trained. A medical assistant can perform the test after a short e-learning certification—an RN or dedicated vascular technician is not required. Learn more about autonomic nervous-system testing methods.

Does HealthWright Technologies treat patients directly?

No. HealthWright Technologies is a medical-device company that sells diagnostic and therapeutic technology —along with training, implementation, and ongoing support—to independent physicians and their practices. The clinical use of TM-Flow, and all patient care, remains with the purchasing practice and its providers.

How is TM-Flow testing reimbursed?

Each code may be billable when the corresponding test is medically necessary and documented for a symptomatic or at-risk patient; coverage and amounts vary by payer.
