[IV Sync, Humana] Incorrect Remaining Benefit Amounts for Members with Dual Plan Enrollment (Payer-Side Issue)
Subscribe
Identified - We've identified an issue affecting real-time (sync) eligibility responses from Humana for members who were enrolled in two different plans during the same plan year. In these cases, Humana is returning duplicate or inconsistent remaining benefit amounts under plan limitations.
This is a known accumulator logic issue on Humana's side, not an issue with Zuub's platform, and it is limited to IV Sync requests. IV Async is not affected. Humana has confirmed the issue and is working on a fix, but has not provided an ETA at this time.
For Humana members affected by this issue, we recommend confirming remaining benefit amounts directly with Humana until a resolution is in place.
We'll update this incident as we receive more information from Humana.
