To define the cost necessary to run an adult cochlear implant (CI) program, including assessment, subsequent implantation, and follow from the Canadian provincial government perspective. Time-driven activity based costing (TDABC) of a CI program. Adult provincial CI referral center. Clinical scenario pathways were developed and verified with stakeholders. TDABC was then applied to all steps involved in the pathway. Costing was based on all patients referred to the CI program in 2019. All costs were calculated in Canadian (and American) dollars as of 2023. This is the first TDABC model of a CI program to the authors knowledge. In 2019, 296 referrals were placed to our CI program and 154 were surgical candidates. The calculated total annual cost for patients referred in 2019 was $4.542 million ($3.365 million USD), or $29,511 ($21,865 USD) per patient implanted. The largest cost contributors to patient cycles were surgical day costs ($23,164 [$17,185 USD] for unilateral, $43,356 [$32,165 USD] for bilateral), switch-on day costs ($1068 [$791 USD] for unilateral, $1511 [$1120 USD] for bilateral), and audiological assessment costs ($692 [$512 USD]). The highest single cost on the pathway was due to the actual CI device when used. Across other patient steps, the highest costs were related to labor. This TDABC evaluation of a CI program found the annual cost required to meet all referrals was $4.542 million ($3.365 million USD), or $29,511 ($21,865 USD) per patient implanted. The highest single-cost was associated with the CI device itself.
