A Spanish-speaking Medicare beneficiary gets a renewal notice in English, calls in confused about a plan change she doesn’t fully understand, and works through the conversation with an agent who can only get her halfway there. None of that shows up as a single failure. It shows up as a longer call, a follow-up call, and sometimes a lapse in coverage nobody intended.

Bilingual open enrollment support isn’t one capability a healthcare line either has or doesn’t, it fails or holds at four distinct points in the enrollment funnel, and most staffing plans only account for one of them. Fixing the call without fixing the other three just moves the failure point somewhere less visible.

Why bilingual capacity gets treated as a nice-to-have, not a capacity plan

The scale here is larger than most staffing plans assume. About 26 million people in the United States have limited English proficiency, roughly 8% of the population age five and older, and most of them speak Spanish, according to KFF’s 2023 survey on language barriers in health care, and about a third of that population reported that a language barrier made it hard to get the care or coverage information they needed in the past three years.

This isn’t the same problem as the general staffing lead-time math this article isn’t making, how many trained agents, ready how far in advance, which open enrollment already creates on its own. Bilingual capacity is a different, narrower constraint layered on top of it: even a fully staffed line can be short on the specific combination of trained, bilingual agents at the specific hours when Spanish-speaking callers actually call, which a headcount plan alone doesn’t fix.

A roster that looks fully staffed on paper can still leave a Spanish-speaking caller waiting longer than an English-speaking one calling at the same moment, and that gap rarely shows up until someone goes looking for it specifically.

The four points where language capacity actually fails

Language capacity doesn’t fail evenly across an enrollment funnel. It fails at four specific points, and each one has a different fix:

• Awareness and outreach. Plan comparison materials and reminder mailers that go out in English only miss a share of the audience before the funnel even starts, regardless of how well-staffed the phone line is later.
• The plan comparison call itself. The eligibility and benefits questions an insurance line fields on the same calendar as healthcare enrollment require a bilingual agent available at the specific hours when Spanish-speaking callers actually call, not just somewhere on the roster that day, coverage timed to when the calls actually arrive rather than to a generic shift pattern is what closes that specific gap.
• Completing the enrollment or renewal form. This is where the data is most stark: 99% of respondents who don’t read English well, in one federal study, said their renewal notice arrived in English anyway, 85% said they needed help reading it, and 94% needed help completing the form, meaning the paperwork itself is often the biggest single barrier, not the phone call.
• Post-enrollment confirmation. A confirmation that goes out in English, to someone who enrolled in Spanish, creates a second round of “did this actually work” calls that a well-designed handoff would have prevented in the first place.

The same bilingual gap Redial’s healthcare admin research has already documented shows up in a narrower workflow inside insurance verification too, that process has its own version of the awareness, conversation, paperwork and confirmation sequence, and it fails at the same kinds of seams when bilingual capacity isn’t built into all four rather than just the call.

What closing the gap actually requires

Closing this gap starts earlier than the phone call. The intake step where a lot of this volume actually starts is where a language preference gets recorded, or doesn’t — and that single data point determines whether every downstream touch, from the plan comparison call to the renewal notice, happens in the right language automatically or has to be re-discovered every time.

The team actually answering the plan questions, coverage confirmations and enrollment support work that make up a healthcare line’s daily volume needs bilingual coverage built into the staffing plan at each of the four points, not concentrated only at the call center, because the call is often the point where an earlier, unaddressed gap finally surfaces as a longer, harder conversation than it needed to be.

The takeaway

The eight weeks of open enrollment don’t create the bilingual capacity gap. They expose it, all at once, to a population large enough that a gap at any one of the four points shows up as a real number of missed or delayed enrollments, not a rounding error in next year’s numbers. A plan that checks all four points before the season starts is the only version of this that actually closes the gap rather than just moving where it becomes visible.
