After Applying for the CareASSIST Copay Program

Upon receiving the CareASSIST application, CareASSIST Patient Access Specialists will review it for copay program eligibility. If your eligibility is confirmed, you will receive a notification via US mail that contains your copay number. This information should be retained and included with any reimbursement claims that you submit.

Please note: CareASSIST will only review applications for copay program eligibility if the Copay Assistance box is checked.

You will be enrolled in the program for 12 months dating from the time of approval, and will be evaluated for continued eligibility on an annual basis. Enrollment will be renewed if eligibility is confirmed.

If you are ineligible for this program, now or after an annual review, CareASSIST will notify you by US mail.

How CareASSIST Handles Patient Reimbursement

In order to be reimbursed, you must submit the following paperwork to CareASSIST within 120 days of the date of treatment.

  • Your invoice for your ELITEK prescription
  • Your insurance company’s explanation of benefits
  • Payment receipts
  • Billing statements
  • A completed proof of expense form

You may seek reimbursement for treatments that you have received in the 120 days prior to the date of enrollment in the CareASSIST Copay Program.

Note that some healthcare providers may choose to submit all documentation necessary for reimbursement on your behalf. Discuss these details with your healthcare provider or their office staff.

After CareASSIST receives all required documentation, the copay billing specialist team will perform a review to determine your out-of-pocket costs. Once these materials are reviewed and approved, you will receive a reimbursement check from CareASSIST in approximately 7 to 14 business days.
