CoverOne provides co-pay assistance for privately-insured BAVENCIO® (avelumab) patients with co-pay/co-insurance responsibilities who meet the program eligibility criteria. Limits, terms and conditions apply, see below

  • HCPs may submit an application for co-pay assistance for their privately-insured patients by submitting an enrollment form through the CoverOne Enrollment Portal or by faxing a completed Enrollment Form to 1-800-214-7295.
  • We are not permitted to offer CoverOne Co-pay Assistance to any claims covered, paid or reimbursed, in whole or in part, by Medicaid, Medicare, or other federal or state healthcare programs.
  • Enrollment in the co–pay assistance program does not guarantee assistance. Whether an expense is eligible for the CoverOne Co-Pay Assistance benefit will be determined at the time the benefit is paid. Eligible co-pay expenses must be in connection with a separately paid claim for BAVENCIO® administered in outpatient setting, which is otherwise covered by a private/commercial insurance plan.
  • Enrolled patients may be eligible to pay as little as a $0 co-pay for each treatment for Bavencio, up to a maximum of $30,000 per year.
  • Once the annual co-pay assistance limit is reached, enrolled patients are responsible for paying all co-pays and any balance not covered by CoverOne.




The patient co-pay assistance program is not contingent on any past or commercial sale of BAVENCIO. The co-pay program does not assist with inpatient hospital claims, or in any bundled payment arrangement where there is no separate patient co-pay for BAVENCIO, and does not assist with healthcare premiums or drug administration services.
