For referring physicians

Refer your patient to EECP, in under five minutes.

A covered, non-invasive next-line therapy for refractory angina, chronic stable heart failure, and patients who’ve exhausted, or declined, revascularization. We handle prior auth, scheduling, transport coordination, and the report you want back in your chart.

Why physicians refer to Flow Therapy

The patient stays your patient.

EECP is a defined 7-week course, not a transfer of care. Your patient comes back to you with measurable improvement, a clean progress note, and unchanged medications.

01

You stay informed

You receive a written progress note at session 1, session 10, session 25, and at course completion, including CCS / NYHA class change, 6-minute walk delta, and any medication-related observations.

02

No medication conflicts

EECP doesn’t require holding antiplatelets, anticoagulants, or beta-blockers. Patients continue your prescribed regimen unchanged for the entire course.

03

Covered, predictable billing

Medicare (NCD 20.20) and most commercial plans cover HCPCS G0166 for refractory angina. We handle prior authorization where required and bill the payor directly, your office is not involved.

04

Guideline-recommended

Guideline-recommended therapy supported by two RCTs (MUST-EECP, PEECH) and the IEPR registry (n=1,427). In registry data, roughly 75–80% of patients improve by at least one CCS angina class (IEPR registry; Soran 2006).

The evidence in brief

Backed by 500+ studies, trusted by experts.

A short overview of how counterpulsation works, what the randomized and registry data show, and where EECP fits alongside optimal medical therapy.

  • Which patients see the most durable benefit
Candidate criteria

Who's the right patient for EECP?

Refer if
  • Refractory angina. CCS Class III or IV symptoms despite optimal medical therapy.
  • Revascularization exhausted or declined. Prior CABG/PCI without symptom resolution, or patient ineligible (diffuse disease, microvascular angina, frailty).
  • Stable systolic heart failure. NYHA Class II–III, EF ≥ 25%, on guideline-directed medical therapy.
  • Recurrent ED visits or admissions. Two or more cardiac-related contacts in the prior 12 months.
  • Stable patient on optimized medications. No active titration; reasonable functional capacity for 1-hour sessions.
  • Quality-of-life decline. Patient reports they've stopped doing things they used to enjoy because of chest pain or shortness of breath.
Hold off if
  • Severe aortic regurgitation, counterpulsation worsens AI.
  • Severe peripheral arterial disease with critical limb ischemia or open ulcers in the leg cuff field.
  • Active DVT or PE, defer until anticoagulation is established and clot is stable.
  • Recent cardiac catheterization (within 2 weeks) or active major bleeding.
  • INR > 3.0 or platelets < 75K.
  • Uncontrolled HTN (sustained > 180/110), decompensated CHF, active arrhythmia interfering with ECG sync, or pregnancy.
Not sure?

Send the referral anyway. Our medical director reviews every chart within 24 hours and will call you directly if there's a contraindication or a question. No patient is enrolled without a clear go-ahead.

From referral to outcomes report

Four touchpoints with you, then a finished chart.

Your office sends a referral. Everything between that moment and a closed care episode is on us.

  1. 01
    Day 0

    You submit the referral

    Fax, online form, or EMR (Epic, Athena, eClinicalWorks). Include your H&P, recent cardiology note, ECG, and echo. If you've already documented refractory status, that's all we need for prior auth.

  2. 02
    Within 24 hours

    We call the patient

    Our intake nurse calls your patient, explains the therapy, books their consult, and arranges transportation if covered by their plan. We also call your office if anything in the chart raises a question.

  3. 03
    Week 1 – Week 7

    35 sessions, with progress notes back to you

    The patient is treated at our clinic 5 days a week. You receive a written progress note at session 1, 10, 25, and 35, with CCS class, NYHA class, 6-minute walk, PROM scores, and any clinical observations.

  4. 04
    Course completion

    Final outcomes report & handoff back

    One-page summary with pre/post measures, recommended follow-up cadence, and any flagged items for your visit. Patient is returned to your active panel with no transfer of care. We do not prescribe.

Physician FAQ

The questions referring physicians ask first.

Does my patient need prior authorization?

Medicare and Medicare Advantage: no, coverage is via NCD 20.20 for refractory angina, and your chart documentation is sufficient. Commercial plans: usually yes, and we handle it. We submit the prior auth, follow up with the payor, and only schedule the patient after approval is confirmed. Your office is not asked to chase auth.

How quickly can my patient start?

Most patients are scheduled for their first session within 5–10 business days of the referral arriving, assuming a clean prior auth. Complex commercial auth can push that to 2–3 weeks. We notify your office of the start date.

How are you going to communicate with me?

Four scheduled progress notes (session 1, 10, 25, 35) plus a final outcomes summary, delivered via fax, secure email, or direct EMR integration depending on your preference. Plus an ad-hoc call from our medical director for any clinical event during treatment (BP changes, new symptom, missed sessions, etc.).

Will EECP interfere with my patient's medications?

No. Patients continue all your prescribed cardiac medications during the course, antiplatelets, anticoagulants, beta-blockers, nitrates, statins, diuretics. We don't titrate, hold, or substitute anything without explicit instruction from your office.

My patient has a pacemaker / ICD. Still eligible?

Yes, pacemakers and ICDs are not a contraindication. We synchronize counterpulsation to the paced rhythm. The only related caution is sustained ventricular arrhythmia that prevents reliable ECG gating; in that case we'd defer until rhythm is stable.

What's the out-of-pocket cost to the patient?

Medicare: standard 20% coinsurance per session, fully covered if patient has a supplement. Commercial: varies by plan, most patients pay their normal specialty-visit co-pay (typ. $25–$50) per session. We verify benefits upfront and tell the patient their estimated cost before they commit.

What if my patient doesn't respond?

Roughly 1 in 5 patients may not achieve a one-class CCS improvement (IEPR registry; Soran 2006). We flag non-response by session 25 and discuss with you whether to continue, modify, or stop. Either way, you receive a full outcomes report and the patient returns to your panel for next-line management.

Where are your clinics located?

11 centers across 3 states, see the locations page for the full list. We route every referral to the closest clinic by patient zip and offer covered transportation in regions where the plan benefits include it.

Share with your patient

The answer to "but what is it, exactly?"

Most patients have never heard of EECP, and a therapy they cannot picture is an easy one to decline. This short film explains the treatment in plain language and shows what a session actually looks like, so your patient arrives at their consult already comfortable with the idea.
