Summary
Molina Healthcare of California and Central Health Medicare Plan updated their provider roster submission requirements, implementing a new policy where entire roster submissions will be rejected if any errors are found. The bulletin identifies common rejection reasons including missing physician service location county, primary specialty taxonomy, and supervising physician information for nurse practitioners.
Action Required
Immediately: Provider groups with delegated credentialing must review and update their roster preparation processes to ensure all required fields are complete before submission. Verify physician service location county is provided, primary specialty taxonomy is included, only one suite number per column, supervising physician information is complete for nurse practitioners (unless NP holds 103/104 license), 'List in Directory' indicator is present, and provider designation is valid. Contact assigned Provider Relations Representative if experiencing frequent rejections to schedule a review meeting.
