Welcome to the AOPA Co-OP, a compendium of O&P!

An online reimbursement, coding, and policy resource, the Co-OP includes a collection of detailed information with links to supporting documentation for the topics most important to AOPA Members. A Wikipedia of all things O&P, it incorporates a crowdsourcing component, which is vetted by AOPA staff, to garner the vast knowledge and experience of our membership.

Each AOPA member company receives one license, but multiple people can use the same login at the same time. Please assign one contact for your company. To sign up, please email
