Public Statement

a)    This policy will apply to all services performed on or after the above revision date which will become the new effective date.

b)    For all services referred to in this policy that were performed before the revision date, contact customer service for the rules that would apply.

1)    The Impella or Tandem Heart pump can temporarily improve blood output from the heart through an externally introduced catheter. This technology has limited use for patients with low heart output who are having high-risk heart procedures or with shock after a heart attack or heart surgery (that has not responded to the usual measures).  Any use beyond this is experimental. It is not intended for routine heart surgeries or for routine resuscitation.

2)    All claims involving the use of Impella or Tandem Heart pumps will be reviewed for appropriateness. These are disposable supplies and should not be coded as implants or DME. Any experimental use will not be covered.

3)    Any elective use of Impella that does not have a signed informed consent, documenting discussion of potential increased risk of complications (compared to intra-aortic balloon pump) will not be covered.

Medical Statement

QualChoice considers a FDA-approved percutaneous left ventricular assist device (pVAD) (e.g., the TandemHeart and the Impella) medically necessary for the following indications:

1)    As an adjunct to percutaneous coronary intervention (PCI) in the following high-risk patients:

a)    Persons undergoing unprotected left main or last-remaining-conduit PCI with ejection fraction less than 35 %; or

b)    Persons with three vessel disease end diastolic ejection fraction less than 30 %.

2)    Providing short-term circulatory support in cardiogenic shock refractory to vasopressor medications and intra-aortic balloon pump (IABP).

QualChoice considers pVADs experimental and investigational for all other indications because of insufficient evidence in the peer-reviewed literature. This includes the use of pVADs as an adjunct to augment or intensity ACLS or other resuscitation efforts in the face of cardiac arrest or the periarrest period.  There have been no controlled trials studying the early use of pVADs in pericardiac arrest patients or intra-arrest as a bridge to return of spontaneous circulation.

 

Review of the available research for use of the Impella 2.5 pVAD has resulted in a Hayes “C” rating.  “This rating reflects a low-quality body of evidence suggesting that the Impella 2.5 is at least as effective as an intra-aortic balloon pump in reducing major adverse events during high-risk PCI. This Rating also reflects considerable uncertainty regarding the comparative benefit of the Impella 2.5 versus high-risk PCI without ventricular assist devices (VADs) or with alternative VADs, long-term efficacy and safety, and optimal patient selection criteria.”

 

Hayes is recognized as a leader in evidence-based rating of medical technologies with the following ratings used to determine appropriate use of technology:

·         A: Established benefit

·         B: Some proven benefit

·         C: Potential but unproven benefit

·         D1: No proven benefit and/or not safe

·         D2: Insufficient evidence

FDA approval of a technology may or may not correlate with the evidence-based Hayes rating.

 

On 2/14/2018, the FDA expanded indications for Impella 2.5 to include high-risk PCI regardless of LV function.  Unfortunately, there is not universal agreement on what constitutes high-risk PCI (absent reduced LV function).  Therefore, given the lack of a consistent definition for high-risk PCI, the expanded FDA indications do not have clear support in the medical literature and are still considered experimental and investigational.
