Outreach budgets get cut first because they are hard to defend with numbers. The fix is a transparent return-on-investment model that any chief financial officer can challenge line by line. Below is a structure that holds up to scrutiny because it separates what outreach can plausibly influence from what it cannot.
The five inputs that matter
First, the at-risk population: the members facing a renewal or a work-requirement verification in a given window. Second, the procedural-loss rate: the share of that population historically lost for paperwork reasons rather than true ineligibility. Third, the recoverable fraction: how many of those procedural losses are realistically preventable through timely, understandable, multilingual contact. Fourth, the PMPM value of a retained member and the expected retention duration. Fifth, the fully-loaded cost of the outreach program itself.
The arithmetic is straightforward. Recoverable members equal at-risk population times procedural-loss rate times recoverable fraction. Revenue protected equals recoverable members times PMPM times months retained. ROI equals revenue protected minus program cost, divided by program cost. The discipline is in resisting inflated assumptions at every step.
A worked example
Take a plan with 100,000 members facing renewal over the notice window that runs roughly June 30 to August 31, 2026. Assume a 15 percent procedural-loss rate without intervention, which is conservative against the Arkansas precedent where about one in four affected enrollees lost coverage. That is 15,000 members at risk of avoidable loss. Assume outreach can recover 30 percent of them, or 4,500 members. At a $450 PMPM retained for an average of eight additional months, that is about $16.2 million in protected revenue.
If the outreach program costs $2 million fully loaded, the ROI is roughly seven to one. Even if every assumption is halved, recovering only 15 percent at a higher cost, the program still clears its own expense. That asymmetry, large upside and a floor that rarely goes negative, is why retention outreach is one of the safer bets in plan operations.
Two cautions keep the model honest. Do not count members who would have renewed anyway; the recoverable fraction must reflect incremental retention, not total retention. And do not assume a single mailed notice equals contact. Real recovery depends on reaching members in their language, on the channel they actually use, before the deadline rather than after it. The model is only as credible as the contact strategy underneath it.
