Coverage Criteria for tafamidis (Vyndaqel / Vyndamax)
Initial and continuation therapy requirements
Covered when documentation supplied with the prior authorization request supports a diagnosis of transthyretin-mediated cardiomyopathy (ATTR-CM) and the clinical indication for tafamidis (new start or continuation) as described below.
Requests will be excluded or may be denied when documentation does not confirm a diagnosis of transthyretin-mediated cardiomyopathy. Acceptable diagnostic confirmation must include one of the following: genetic testing demonstrating a pathogenic or likely pathogenic TTR variant (or documentation of wild‑type ATTR) OR a Tc‑99m PYP imaging scan with Grade 2 or 3 myocardial uptake OR a cardiac tissue biopsy showing amyloid deposits. Requests that lack any of these confirmatory findings and that also fail to document clinical signs or symptoms of heart failure may be excluded from coverage.
For continued tafamidis therapy, the request must include documentation that the patient has experienced a clinically beneficial response while on treatment. The form explicitly asks whether there has been a documented beneficial clinical response and lists examples such as reduction in cardiovascular-related hospitalizations, improvement or stabilization in 6‑Minute Walk Test, improvement in symptom burden or frequency, and improvement in quality of life. Continued coverage may be denied if these response measures are not documented and supporting clinical records are not attached.
