1. Verify patient benefits

Gateway to NUCALA can help you understand the insurance process for covering NUCALA. You may also contact the specialty pharmacy, or patient’s payer directly.




Initiate a benefits investigation

Verify benefits by working with Gateway to NUCALA or contacting the payer directly. Benefits investigations do not guarantee coverage. If your patient is not enrolled in Gateway to NUCALA, please complete the enrollment form above.

If the patient will receive treatment at an alternative site of care (ASOC):


Consult the patient’s insurance or contact Gateway to NUCALA to identify an appropriate ASOC. Work with the ASOC to determine responsibility for benefits investigation and prior authorization.


Prior authorization (PA)

  • Obtain needed forms from the patient’s plan
  • Follow up with the patient’s plan to determine PA submission status if requested
