When people think about Star Ratings, they usually think about quality measures, member experience, and plan performance.
They do not usually think about one phone call.
But for Medicare Advantage and Part D plans, call center performance plays an important role in how CMS evaluates accessibility and service. And when a caller needs an interpreter, that interaction becomes even more important.
That is because CMS is looking at more than whether a call gets answered. It is also looking at whether members can get clear, timely help in the language or format they need.
For plans, that makes interpreter access more than a helpful service. It makes it part of a broader compliance and quality strategy.
Why This Matters
CMS continues to include Call Center Foreign Language Interpreter Availability in Star Ratings for both Part C and Part D. That means language access is not operating on the sidelines. It is part of how plan performance is measured. CMS’s 2026 Star Ratings materials confirm that this measure remains in place, using call center data from February 2025 through May 2025, and that Star Ratings continue to shape how plans are viewed by members and how Medicare Advantage quality bonus payments are determined.
In practical terms, that means a member’s experience trying to reach language support can contribute to a publicly reported quality outcome.
That is a big deal.
Star Ratings influence how confidently members choose a plan. They also affect financial performance. So when interpreter access breaks down, the impact can go beyond one frustrating call. It can affect member trust, operational performance, and how a plan is perceived in the market.
What CMS Is Really Looking For
At its core, CMS is asking a simple question: can members get the help they need quickly, clearly, and in a way they can understand?
That includes members who need support in a language other than English. CMS ties those expectations to customer call center requirements and uses call center monitoring to evaluate whether plans are meeting them in practice.
This is why strong performance does not come from scrambling during testing season. It comes from building language access into everyday operations so the experience feels natural, consistent, and reliable every time the phone rings.
What Strong Performance Looks Like
Plans that do well in this area usually have a few things in common.
They do not treat interpreter access as a special exception. They treat it as a standard part of member support.
They use clear, traceable workflows so interpretation requests move through controlled systems with the right documentation in place. They make thoughtful interpreter assignments based on language, modality, program requirements, and healthcare experience. And they make sure calls are handled consistently, whether the interaction is routine, high-stakes, or part of a CMS evaluation.
They also test before go live.
Pre-go-live test calls can help uncover risks early, whether the issue is interpreter routing, agent handoff, call flow confusion, documentation gaps, or inconsistent call handling. Finding those issues in advance gives plans the opportunity to correct them before they affect member experience or CMS performance.
In other words, strong plans are ready before the test call happens.
That readiness matters because CMS expectations are not just about policy. They are about proof. Plans need to be able to show that calls were answered in a timely way, that communication was accurate, and that members were supported appropriately.
How BIG Approaches CMS Readiness
At BIG, we believe CMS readiness should feel built in, not bolted on.
That is why we apply the same governance-first, audit-ready approach to CMS interpretation support that we use in regulated translation environments. The goal is simple: make every interaction consistent, traceable, and ready to stand up to review.
Our CMS interpretation compliance process includes:
- Structured, traceable call workflows
- Qualified interpreter assignment based on language, modality, and healthcare specialization
- Real-time monitoring and documentation
- Audit-ready records that support proof-based compliance
- Pre-go-live test calls to identify and resolve risk areas before launch
This means interpretation requests are routed through controlled systems that capture essential operational and quality indicators, such as ASA, AHT, interpreter assignment, call handling consistency, and other documentation needed to support compliance review. It also means CMS test calls are handled the same way as live member calls, so there is no artificial test-only behavior that can create gaps or inconsistencies.
That consistency is where confidence comes from.
Training Matters Just as Much as Process
Even the best workflow depends on people knowing exactly what good looks like.
BIG prepares interpreters and staff for CMS test calls through targeted, role-specific training that reflects regulatory expectations and real-world call center demands.
For interpreters, that includes:
- CMS program awareness
- Expectations for accuracy and completeness
- Appropriate tone and neutrality
- Handling member rights, notices, and sensitive healthcare content
- Approved medical terminology and member-friendly delivery
Interpreters are also coached to treat every call as audit-eligible. That mindset helps create consistent performance across both live and evaluated interactions.
For staff and QA teams, training focuses on:
- CMS test-call criteria and scoring
- Monitoring and documentation standards
- Escalation procedures
- Corrective-action protocols when risks are identified
- Operational performance measures such as ASA, AHT, and service consistency
When everyone understands the process and the standard, calls run more smoothly and plans are better positioned to perform well.
What Happens When Scores Fall Short
No system is perfect. What matters is how issues are identified and addressed.
BIG uses a continuous quality improvement model to help strengthen CMS readiness over time. When a call scores lower than expected, we do not stop at the result. We look at why it happened.
That includes post-call quality review, root-cause analysis, and targeted corrective action.
Depending on the findings, that might mean:
- Interpreter coaching or retraining
- Terminology reinforcement or glossary updates
- Workflow changes to improve response time or call handling
- Heightened QA monitoring until performance stabilizes
- Additional test calls to confirm improvements before full rollout
This kind of structured follow-through helps reduce recurrence and improves readiness across the board.
The Bigger Picture
CMS call center monitoring is really about member access.
Can someone get the information they need without long delays? Can they communicate in the language or format that works for them? Can they trust the answer they receive?
Those are simple questions, but they carry real weight.
When language access is built into daily operations, testing becomes less stressful and more predictable. Agents know what to do. Interpreters are prepared. Members get a better experience. And plans are in a stronger position to protect performance.
That is the real value of getting interpreter access right.
Why Plans Partner With BIG
BIG helps plans make CMS readiness part of a stronger, better member experience.
We support clients with:
- Fast access to qualified interpreters
- Coverage for commonly tested languages and dialects
- Training support for agents and operational teams
- Quality oversight focused on clarity, timing, and accuracy
- Audit-ready documentation and continuous improvement support
- Pre-go-live testing to surface and resolve issues early
With the right partner, CMS testing becomes less about reacting to pressure and more about showing what a well-run operation already does every day.
Turning Readiness Into Results
A single phone call may seem small.
But in the CMS environment, it can say a lot about a plan’s readiness, accessibility, and member experience.
That is why strong interpreter access matters. It helps plans deliver better service, strengthen compliance, and protect the performance measures that shape Star Ratings.
At BIG, we help make that happen in a way that feels practical, consistent, and ready for the real world.
