If you obtain your Korsuva through NiceRx, you will only pay $49 a month regardless of the retail price of your medication.

Am I eligible for the Korsuva patient assistance program?

You could receive your Korsuva without paying the full retail price if you meet the eligibility criteria for assistance. The eligibility requirements are set by the pharmaceutical companies that are providing assistance programs. At NiceRx, we review each application individually, although the main factors considered by most programs are:

  • I am a permanent, legal resident of the United States or Puerto Rico
  • I am uninsured or my insurance doesn’t cover my medication

We do everything that we can to take the hassle and stress out of applying for patient assistance programs. Simply start by filling in our enrollment application. We will ask for details about your healthcare provider, your insurance, and your household income. This information is required by the pharmaceutical companies you are applying to for assistance. We may also be able to help you access patient assistance for other medications that you have been prescribed, so be sure to tell us about any medications you are taking as well as Korsuva.

NiceRx will review the information you have provided, and if we determine that you may be eligible for assistance, we will seek to enroll you in the Korsuva patient assistance program. We will handle the enrollment process for you by working with your healthcare provider and preparing all the required paperwork for your doctor to sign. We will also request your Korsuva medication refills on your behalf for up to 1 year once you are enrolled in the program.

We may be able to help you if you have insurance, including if your insurance company will not pay for your Korsuva medication, or if you have a high copay or coinsurance responsibility. We may even be able to assist if you do not have insurance. Please fill in our enrollment application to find out more.
