The carrier-locked HSA is one of the most quietly damaging artifacts of the legacy benefits stack. When a member changes jobs, their HSA either (a) gets converted to a fee-bearing retail account, (b) becomes nearly impossible to log into, or (c) gets forgotten entirely and slowly drained by maintenance fees.
Why it happens. Carrier-locked HSAs were built into a business model where the carrier — UnitedHealth, Anthem, Aetna — bundled the HSA with their medical plan. The lock-in was the point. When the member left the carrier, the account got demoted to a retail product.
What it costs members. Industry data suggests that 30–40% of HSA accounts at carrier-locked providers go dormant within 24 months of a member's job change. The fees on those accounts are a quiet leak of money members thought was theirs.
What carrier-agnostic infrastructure does differently. The account follows the member. The card works the same. The app shows the same balance. The investing portfolio stays in place. The member doesn't have to know — or do — anything.
For employers, this matters less in retention math and more in alumni-NPS. The members who leave well speak about your benefits package for years after they're gone.
