(Code 460) **Q: What does the “Mediator Pool Full for Receiver” (Code 460) error mean?** This message indicates that the payer’s eligibility processing system was temporarily overloaded or unable to handle additional requests. **Q: Why does this happen?** It typically occurs when the payer’s system is experiencing high traffic or performance issues, preventing it from processing new eligibility inquiries. **Q: How should I resolve this error?** There’s nothing you need to change on your end. Wait and resubmit the eligibility inquiry later the same day or within 24 hours, once the payer’s system load has decreased. **Q: Does this error mean there’s a problem with Claim.MD?** No. The issue is on the payer’s end, not within the Claim.MD system. Once the payer’s system stabilizes, your eligibility requests should process normally.
