When an employer group shifts from one health plan to another, why not allow them to take their claims data to the next health plan? That way, the new plan would gain immediate knowledge of the specific disease burden faced by its new members and be able to act accordingly vis-à-vis care management programs and other interventions. As it stands now, the new plan would have to wait many months and even then would lack the history that the earlier plan no longer needs. And when the new plan “finds out" about a member's condition, it might be due to a claim for an event that could have been prevented had the carrier had access to the earlier data.
Here’s how the system would work. When a group signs up with a carrier, it could reserve the right to have its data transferred if it changes carriers. Obviously, it wouldn’t be able to “see” its own patient-identified data any more than it does now, but the data would accompany the change of carriers.
