Two clinics can give their behavioral health care managers the same caseload number on paper and end up with completely different outcomes. One team feels like they have room to breathe, patients improve, and PCPs are enthusiastic. The other feels constantly behind, worried about the patients they have not called yet, and unsure whether they can accept more referrals. The difference usually is not the headline “80 patients per care manager.” It is how those panels are built, how the work is structured, and what support sits around the care manager.
This post looks at caseloads from three angles: why identical numbers behave so differently, what care managers themselves describe as their real pressure points, and practical ways leadership teams can rightsize caseloads so they protect both access and quality.
On a dashboard, caseloads are simple. A care manager has 70, 90, or 100 enrolled patients. In real life, “90 patients” can mean very different things depending on who those patients are and how the clinic runs CoCM.
One of the biggest hidden factors is acuity and stage of care. A panel that is mostly people in their first few months of CoCM, still in crisis or with severe symptoms, feels very different from a panel where a good proportion of patients are in a maintenance phase. Early in treatment, calls tend to be longer and more frequent. Patients may be adjusting to medication changes, dealing with unstable housing or relationships, or testing whether they can trust this new support. Later on, contact often shifts into shorter checkins that confirm progress and catch early signs of relapse. On paper, both groups are “enrolled.” For the care manager, the workload is not the same.
The AIMS Center at the University of Washington, which developed the Collaborative Care model, notes that caseload size is a function of program scope, complexity, and the socioeconomic characteristics of the population served. Their guidance suggests that a full-time care manager in a moderate to high complexity setting, such as a federally qualified health center serving Medicaid or uninsured adults, should typically aim for around 80 patients. However, this assumes that 75 percent of their time goes to direct patient care, not administrative tasks.
Contact patterns matter as well. Some clinics set the expectation that new or higherrisk patients will have weekly or bi-weekly contact, at least for the first 8 to 12 weeks. Others lean on monthly checkins, with more intensive outreach only when scores worsen. A caseload made up of patients who are due for weekly calls occupies a very different amount of time than the same number of patients due for monthly calls. If leaders only look at the raw panel size, they can miss the fact that the clinic has shifted toward more “heavy” patients without adjusting the caseload target.
The third factor is how much nonclinical work sits on the care manager’s shoulders. Documentation, registry updates, scheduling, chasing down information in the EHR, and coordinating with outside services can quietly absorb hours. If a care manager is spending a large part of the day managing systems rather than talking with patients, their effective clinical capacity shrinks. Two programs can claim the same caseload benchmark, but in one, care managers are supported by simple tools and clear workflows, while in the other they are fighting the system every day. The caseload number looks identical; the experience is not.
When you ask behavioral health care managers about caseloads, they rarely start by quoting a specific number. Instead, they talk about what their day feels like.
One theme that comes up often is the emotional load of high risk and complex cases. Supporting people who are suicidal, trapped in unsafe relationships, or dealing with years of trauma is demanding work. When a panel has many of these patients at once, care managers can finish the day emotionally drained, even if the caseload looks "reasonable" on a spreadsheet. They worry about whether they missed something important because they had to move quickly to the next call. They think about patients in the evening. The strain is not because they are not capable; it is because the mix of cases and the time available do not match.
Another pressure point is constant context switching. Many care managers describe their day as jumping between very different situations with little time to reset. One appointment might be a structured followup with a patient who is doing well at work. The next is an unscheduled crisis call. In between, there are registry alerts to review, messages from PCPs, and documentation to complete. The brain work of switching between these modes all day is a real bottleneck, even when each individual interaction seems short.
There is also the feeling of being the “catchall” for gaps elsewhere in the system. In some clinics, care managers find themselves hunting for community resources, tracking down lab results, or filling in for social work or case management roles that are stretched thin. They do this because they care about their patients and because they can often get things done. Over time, though, the list of responsibilities grows while the caseload number stays the same. It is easy for leaders to conclude that “we are still within our target range” while staff experience a very different reality.
None of this reflects badly on care managers. If anything, it highlights how committed they are. It also shows why caseloads need to be treated as a design question for the organisation, not a test of individual resilience.
Most primary care leaders feel a genuine tension. On one hand, there is a long list of patients who would benefit from Collaborative Care Management. On the other, there is a responsibility to make sure the patients already in the program are getting enough contact and that staff can sustain the work.
A useful starting point is to define what good CoCM looks like in your setting before you fix a caseload target. For example, you might decide that new patients should receive an outreach attempt within a set number of days, followed by weekly or bi-weekly touches for the next couple of months. You might agree that higher risk patients should have more frequent contact, plus clear escalation routes and consultation support. For patients who are doing well, you might aim for regular maintenance checkins with easy access if scores rise again. Once you have this picture, you can work backwards to estimate how many patients in each stage a single care manager can realistically support.
From there, many organizations find it more honest to think in tiers than in a single number. A highacuity patient simply represents more work than someone in a stable maintenance phase. You do not have to build a complicated scoring system to acknowledge this. Even a simple approach that treats “new or highrisk” patients as a larger share of the panel than “stable” patients can help leaders see when caseloads have become too heavy, even if the headline number has not changed. The goal is not to make the registry more complex; it is to make the invisible pressures visible.
The tools you use for registry and measurement can make a real difference. When they make it easy to see the mix of patient acuity, who is overdue for contact, and how often patients are being reached, care managers can adjust referral volume or redistribute panels before staff hit burnout. When tools are clunky or purely retrospective, care managers are left holding responsibility without the information they need.
According to the AIMS Center, effective Collaborative Care depends on regular caseload review, where the care manager and psychiatric consultant meet weekly to discuss patients who are new to the program or not improving as expected. This practice helps spot when caseloads are becoming unmanageable and when treatment adjustments are needed.
Rightsizing caseloads does not always mean hiring large numbers of new staff. Often it is about how you structure the work around the people you already have. Simply adding staff without adjusting workflows can put both program efficiency and financial stability at risk.
One simple but powerful step is to protect some focus time for clinical work. In many clinics, care managers find that meetings, adhoc requests, and admin tasks fragment their day into five or ten minute pieces. Setting aside a few regular blocks each week where they can focus on higher acuity calls, new intakes, or patients whose scores have worsened can improve both quality and staff experience. It is not about shielding them from the rest of the team; it is about giving them enough uninterrupted time to do the parts of the role that only they can do.
It also helps to be explicit about what “enough contact” looks like. When expectations are vague, care managers carry the mental load of deciding, for each patient, whether they are doing enough. When the team agrees that, for example, new or worsening cases should be contacted at least weekly and stable patients every few weeks, everyone can see more clearly when caseloads make those standards impossible to meet. That clarity supports honest conversations about capacity rather than relying on personal sacrifice.
Finally, it is worth reviewing the non-clinical tasks that have accumulated in the role. Some activities, such as safety planning or clinical coordination, rightly belong with care managers. Others, such as routine reminder calls or certain scheduling tasks, may be better handled by other team members or by simple automations. The goal is not to strip the role down to “just calls,” but to ensure that the time and skill of care managers are used where they have the most impact.
The AIMS Center recommends hiring behavioral health care managers as full-time or nearly full-time staff whenever feasible, noting that care managers who are assigned numerous other duties in a fast-paced clinic setting "often fall behind on effectively managing their CoCM caseload." This recognition that role clarity and protected time matter is backed by decades of implementation experience.
None of these adjustments removes the underlying demand for behavioral health support in primary care. What they do is align that demand more closely with the way your CoCM team works, so that access does not come at the cost of quality or staff wellbeing.
Caseloads in Collaborative Care are easy to talk about as a number. They are harder, and more important, to treat as a set of levers that leaders can design and adjust over time. Acuity mix, contact expectations, workflow design, and role boundaries all shape how that number feels for the care managers doing the work and for the patients they support.
When organizations treat caseloads as a leadership responsibility rather than a test of individual stamina, a few things tend to happen. Patients experience more consistent contact and clearer expectations. PCPs see that their referrals land in a program that can keep up. Care managers feel trusted and supported rather than stretched thin. And the program itself becomes more sustainable.
For a turnkey CoCM partner like April Health, a lot of this design work happens behind the scenes: building registries that support decisions, structuring panels thoughtfully, and giving care managers the right mix of support and supervision. But the core principles are the same whether you are building CoCM internally or working with a partner.
Caseloads are not just a metric to report, they are one of the most powerful levers you have to protect outcomes, experience, and the people delivering care.
