Redesigning the Member Experience to Improve CAHPS and HOS
Every year, Medicare Advantage plans pour resources into CAHPS preparation. They analyze prior year scores, identify at-risk populations, stand up targeted campaigns, and coach call center teams. And every year, many of these same plans are surprised when results don’t reflect the effort.
By the time a survey lands in a member’s mailbox, the experience it measures is already over. Last-minute outreach doesn’t reverse perceptions built across a year of touchpoints. The verdict has already been rendered.
What CAHPS Is Actually Measuring
To understand why most CAHPS interventions fall short, it helps to look at what the survey is actually measuring beneath the surface of each question.
Care Coordination asks whether a member’s doctor had their medical records, whether medications were reviewed, and whether the primary care provider was informed about specialist visits. These aren’t soft perception questions about communication quality; they’re questions about whether an annual wellness visit happened and whether the care team functioned as a coordinated unit when it did. Plans that increase annual wellness visit completion rates almost invariably see Care Coordination scores follow. The survey question is a proxy for the clinical event.
Getting Care Quickly asks whether members received care when they needed it. When a member defaults to the emergency room for a non-emergency, they wait hours, feel frustrated, and report a negative experience. When directed to urgent care, they’re often seen within the hour. The care is the same. The experience, and the CAHPS response, is very different. What looks like a satisfaction problem is actually a care navigation problem.
Getting Needed Care assumes that members are actively engaged with a primary care provider. A member with no established PCP cannot report positive experiences about referrals, specialist access, or care continuity because they aren’t seeking care in the first place. Their absence from the care system reads as dissatisfaction on the survey.
To improve CAHPS, you have to change the actual sequence of clinical events, care decisions, and plan touchpoints that a member experiences across a full year.
The Hidden Culprit: Friction
Member experience research consistently points to a concept that health plans underweigh: reducing the effort required to resolve a problem or complete a task is a more powerful driver of satisfaction than any single positive experience.
Member friction accumulates across dozens of annual touchpoints like the welcome call that never comes, the annual benefit notification that’s too overwhelming to understand, the care gap reminder that misses the actual reason the member has the gap. Each friction point is a small withdrawal from the trust account that CAHPS ultimately measures.
Reducing that friction requires identifying where it occurs, understanding why it occurs for each individual member, and intervening before it calcifies into a negative perception.
Five Things Plans Can Do Right Now
1. Make Wellness a Priority The annual wellness visit is the single clinical event that drives performance across care coordination, medication reviews, specialist referrals, and preventive screenings simultaneously. Plans have seen AWV completion drive measurable lifts across three or more CAHPS and HOS domains at once.
2. Stop Running Parallel Campaigns When Stars, quality, and care delivery teams each run their own outreach with their own data, members receive uncoordinated touchpoints from a plan that appears not to know their situation. That perception becomes a CAHPS response. Coordinating outreach logic across functions by ensuring the right department leads at the right moment is foundational.
3. Redirect Emergency Room Utilization Target members with patterns of avoidable ER use and educate them on appropriate care settings before the next urgent need arises. One regional PPO plan moved 1,900 members to more appropriate care settings, generating an estimated $1.25 million in cost savings while improving the member experience.
4. Treat Benefit Confusion as a Care Gap When proactive call center outreach was deployed to members most likely to complain about their experience, one finding stood out: 50% of those members didn’t fully understand their own benefit design. Individualized benefit education delivered through email, bi-directional texting, and responsive call-backs addresses a friction point that no care gap reminder would ever reach.
5. Address Mental Health Barriers Studies show that 20–30% of Medicare Advantage members experience depression or anxiety, with half remaining undiagnosed or untreated. A six-month pilot covering 340,000 members demonstrated that proactively removing barriers to mental health conversations produced a 27.6% new depression diagnosis rate among at-risk members, a 5% increase in AWVs, a 5% increase in cancer screenings, and a 3% increase in diabetic eye exams. None of those were the direct target of the program. They were the natural outcome of a member who felt supported.
The Signal Framework That Makes It Possible
The plans building durable CAHPS performance have moved from campaign-based engagement to a continuous, signal-driven model that operates in three layers.
Clinical signals identify what has or hasn’t happened: a missed wellness visit, a specialist referral that didn’t result in a completed appointment, a prescription that wasn’t filled.
Situational signals reveal why: is a mobility limitation making transportation the real barrier? Is a recent diagnosis creating emotional overwhelm that’s preventing action on a care recommendation?
Behavioral signals determine how to intervene: what tone, what channel, what message framing will meet this member where they are rather than where a persona model assumes them to be.
When a national health plan deployed this approach across a 150,000-member HMO pilot focused on CAHPS recovery, digital-first outreach combined with proactive call center engagement uncovered that half of likely complainers didn’t understand their own benefit design, while the other half faced scheduling, transportation, and access barriers. Separate root causes requiring entirely different interventions. The outcome: a 5% improvement in mock survey rates, a 15% reduction in overall complaints, a two-star improvement per measure, and an overall four-star rating by the end of MY2023. A rating the plan had not expected to achieve.
The Stakes Are Rising
As CMS moves toward a fully-digital Stars ecosystem and NCQA sunsets hybrid reporting, the gray areas that allowed retrospective management of experience measures are disappearing. Rising cut points mean that the difference between a three-star and four-star rating, and the revenue that separates them. is increasingly decided by experience measures that cannot be addressed in the final weeks of a measurement year.
The plans best positioned for this environment are those that have redesigned the member journey itself: reducing friction at the touchpoints that matter, coordinating care delivery across departments, and building a signal infrastructure that understands each member as their needs evolve.
When the journey is designed well, the survey takes care of itself.
