Summary
Oregon Health Plan (OHP) now covers all medically appropriate treatments for post-COVID/long COVID conditions, including previously excluded services, effective October 22, 2021. When billing for post-COVID treatments, providers must use ICD-10 code U09.9 as a secondary diagnosis and follow specific procedures for covered vs. non-covered services.
Action Required
Immediately: Billing team must use ICD-10 code U09.9 (Post COVID-19 condition, unspecified) as a secondary diagnosis when billing for any treatment of conditions arising from earlier COVID-19 infection. For services not normally covered by OHP, contact the CCO for authorization details (CCO members) or provide treatment but do not bill until OHA updates MMIS system (non-CCO members). Update billing software and train staff on post-COVID billing requirements.
