A CBO in healthcare stands for community-based organization, a nonprofit group that operates locally to connect people with services that affect their health but fall outside the walls of a doctor’s office. Think food pantries, housing assistance programs, transportation services, and legal aid groups. These organizations address the non-medical factors that shape health outcomes, like whether someone can afford groceries, has a stable place to live, or can get a ride to their appointments.
What CBOs Actually Do
CBOs fill the gap between what happens in a clinic and what happens in someone’s daily life. A doctor can diagnose diabetes and prescribe insulin, but if the patient can’t afford healthy food or lives in a neighborhood without a grocery store, their blood sugar will stay dangerously high. CBOs step in to handle those real-world barriers.
The specific services vary widely depending on the organization and the community it serves. Some focus on a single issue like food insecurity, delivering meals to homebound seniors or running community fridges. Others offer a broader range of support: help applying for housing, assistance navigating benefits enrollment, substance use counseling, or childcare coordination. What they share in common is local knowledge. Because they’re rooted in the neighborhoods they serve, CBOs understand the cultural context, language needs, and specific challenges their communities face in ways that large health systems often don’t.
The U.S. Department of Health and Human Services describes CBOs as “cultural translators” that help ensure health interventions actually resonate with the people they’re meant to reach. That’s a practical advantage. A nutrition program designed by a hospital system might not account for the dietary traditions of a specific immigrant community, but a CBO embedded in that community will.
Why Health Systems Partner With CBOs
Hospitals and health systems are increasingly recognizing that clinical care alone doesn’t keep people healthy. Factors like housing stability, food access, and social isolation, often called health-related social needs, play an enormous role. This has pushed health systems to build formal relationships with CBOs rather than simply hoping patients find help on their own.
The data supporting these partnerships is compelling. A Chicago study of people experiencing homelessness with chronic illnesses found that those who received housing and case management through community organizations had 2.6 fewer days in the hospital, 1.2 fewer emergency department visits, and 3.8 more outpatient visits per year compared to those who received standard care. Separately, partnerships between hospitals and local aging services organizations were associated with a $136 reduction in average annual Medicare spending per patient between 2008 and 2013, along with fewer hospital readmissions within a year.
Research published in the Journal of General Internal Medicine found that 26 out of 29 health care organizations studied relied on CBOs to address their patients’ social needs. Hospitals that collaborated more deeply and consistently with CBOs performed better on measures like avoidable hospitalizations and readmission rates.
How These Partnerships Work in Practice
Not all CBO partnerships look the same. They generally fall into three tiers, depending on how deeply the health system wants to integrate social services into patient care.
The simplest model is a one-way referral. A clinic screens a patient for food insecurity or housing instability, then hands them a list of local CBOs that might help. This requires little formal relationship between the health system and the CBO. Staff might occasionally call to confirm a service is available, but there’s no structured follow-up.
A step up from that is a contracted partnership, where a health system pays a CBO to deliver a specific service for a defined group of patients. Examples include providing food boxes to seniors with heart disease, arranging medical-legal aid for patients facing eviction, or coordinating transportation to dialysis appointments. These partnerships need leadership involvement to set up but run day to day through staff-level coordination.
The most integrated model involves health systems partnering with multiple CBOs at the community level, sharing data back and forth through referral platforms, and jointly tracking whether patients’ social needs are being met. Many health system administrators say they pursue this level of partnership specifically to enable two-way data sharing, so they can see not just that a referral was made but whether it led to a result.
How CBOs Differ From Clinics and Health Centers
It’s easy to confuse CBOs with other community health resources, particularly Federally Qualified Health Centers (FQHCs). The key distinction is that CBOs generally do not provide clinical medical care. An FQHC is a federally funded clinic that offers primary care services to underserved populations. A CBO, by contrast, addresses the social and environmental conditions around a person’s health rather than delivering medical treatment directly.
Some CBOs do employ health workers like community health workers or peer navigators who help people manage chronic conditions, but their role is supportive rather than clinical. They might help someone understand discharge instructions, remind them about follow-up appointments, or connect them to prescription assistance programs. The medical decisions still happen at the clinic or hospital.
Data Sharing Remains a Major Hurdle
One of the biggest challenges in CBO partnerships is getting information to flow smoothly between organizations. A CMS evaluation of its Accountable Health Communities Model found persistent interoperability problems on both sides. Health systems often stored social needs data in inconsistent formats within the same electronic health record, making it hard to find and use. CBOs, meanwhile, were frequently asked to participate in multiple referral platforms that didn’t connect with their existing case management systems.
The closed-loop referral platforms that health systems adopt, designed to track whether a referral actually resulted in a service, often lack the invoicing, reporting, and care coordination tools CBOs need. Many CBOs don’t have the technological infrastructure to run these systems at all. Privacy concerns add another layer of complexity. While patients who sign consent forms should theoretically allow data to flow between providers and CBOs, in practice CBOs report they rarely receive patient-specific health outcome data back from health systems. That one-sided dynamic makes it difficult for CBOs to measure their own impact or justify continued participation.
The Growing Role of CBOs in Federal Policy
Federal and state agencies are increasingly building CBOs into the structure of healthcare delivery rather than treating them as optional add-ons. CMS’s AHEAD model, which announced new policy changes in September 2025 for implementation beginning in January 2026, emphasizes whole-person care and population health improvement, areas where CBOs play a central role. The model requires participating primary care practices to engage in state-led transformation efforts that align Medicare and Medicaid approaches to care.
CBOs are also organizing themselves differently to meet this demand. Many are forming networks that allow them to deliver a broader scope of services, cover larger geographic areas, build stronger administrative capacity, and offer health systems a single point of contracting. Instead of a hospital needing separate agreements with a food bank, a housing nonprofit, and a transportation service, a CBO network can bundle those services under one contract. This makes partnerships more scalable for both sides.
