Coverage criteria policies

Advanced drug therapy for pulmonary hypertension: epoprostenol (generic, Flolan® and Veletri®), treprostinil (Remodulin® & Tyvaso®), iloprost (Ventavis®) and sildenafil injection (Revatio®)

These services may or may not be covered by your HealthPartners plan. Please see your plan documents for your specific coverage information. If there is a difference between this general information and your plan documents, your plan will be used to determine your coverage.

Administrative Process

Advanced drug therapies for pulmonary hypertension require prior authorization from HealthPartners Pharmacy Administration.


Advanced drug therapy is generally covered for patients when the following criteria are met:

Prescribed by a pulmonologist or cardiologist, and

  1. A diagnosis of either vasoreactive pulmonary arterial hypertension after trial and failure of calcium channel blocker therapy or in non-vasoreactive pulmonary arterial hypertension, and
  2. A diagnosis of PAH defined as WHO group 1 class of pulmonary hypertension as confirmed by right heart catherization with all of the following pretreatment results:
    1. mPAP ≥ 25 mmHg
    2. PCWP ≤ 15 mmHg
    3. PVR > 3 Wood units

Utilization for all other indications will be reviewed for medical necessity.

Sequential combination use requires documentation of medical necessity (including response to single-drug therapy, and rationale for adding a medication).

Use of sildenafil injection requires verification of medical necessity for the parenteral formulation.


Pulmonary hypertension (PH) is characterized by elevated pulmonary arterial pressure and subsequent right ventricular failure. It is diagnosed by right heart catheterization measurements and defined by a mean pulmonary artery pressure of ≥25mmHg at rest.

Epoprostenol (Flolan, Veletri and generic) is indicated to improve exercise capacity in the treatment of pulmonary arterial hypertension (PAH) (WHO Group 1) and pulmonary hypertension associated with the scleroderma spectrum of disease in NYHA Class III and Class IV patients who do not respond adequately to conventional therapy.

Treprostinil (Remodulin) is FDA-approved for

  1. Pulmonary Arterial Hypertension in Patients with NYHA Class II-IV Symptoms, to diminish symptoms associated with exercise. It may be administered as a continuous subcutaneous infusion or continuous intravenous infusion; however, because of the risks associated with chronic indwelling central venous catheters, including serious blood stream infections, continuous intravenous infusion should be reserved for patients who are intolerant of the subcutaneous route, or in whom these risks are considered warranted.
  2. Pulmonary Arterial Hypertension in Patients Requiring Transition from Flolan, to diminish the rate of clinical deterioration. The risks and benefits of each drug should be carefully considered prior to transition.

Treprostinil inhaled (Tyvaso) is FDA-approved to improve exercise ability in patients with WHO Group I pulmonary arterial hypertension and NYHA Class III symptoms. The effects diminish over the minimum recommended dosing interval of 4 hours; treatment timing can be adjusted for planned activities. While there are long-term data on use of treprostinil by other routes of administration, nearly all controlled clinical experience with inhaled treprostinil has been on a background of bosentan or sildenafil. The controlled clinical experience was limited to 12 weeks in duration.

Iloprost inhaled (Ventavis) is FDA-approved for the treatment of pulmonary arterial hypertension (WHO Group I) in patients with NYHA Class III or IV symptoms. In controlled trials, it improved a composite endpoint consisting of exercise tolerance, symptoms (NYHA Class), and lack of deterioration.

Sildenafil injection (Revatio) is a phosphodiesterase 5 (PDE5) inhibitor FDA-approved for the treatment of pulmonary arterial hypertension (WHO Group I) in adults to improve exercise ability and delay clinical worsening. Studies establishing effectiveness included predominately patients with NYHA Functional Class II-III symptoms and etiologies of primary pulmonary hypertension or pulmonary hypertension associated with connective tissue disease. Limitation of Use: Adding sildenafil to bosentan therapy does not result in any beneficial effect on exercise capacity.
