National Association of Accountable Care Organizations

What National Association of Accountable Care Organizations does

The National Association of Accountable Care Organizations (NAACOS) is a 501(c)(3) member-led nonprofit association founded in October 2012 to serve as the collective national voice for Accountable Care Organizations (ACOs). Headquartered at 2001 L Street NW, Suite 500, Washington DC, NAACOS represents more than 400 ACOs operating in Medicare, Medicaid, and commercial insurance programs, covering an estimated 8–23 million beneficiary lives depending on counting methodology (the organization's own website states 8M+; a secondary source cites ~half of 700 ACOs serving 23M Americans). Members include major health systems (Trinity Health, Mount Sinai, Northwestern Medicine, UNC Health Alliance, Bon Secours Mercy Health, Baylor Scott & White Quality Alliance), physician-led ACOs (Coastal Carolina Health Care, Physicians of Southwest Washington), and ACO enablers such as Aledade.

NAACOS does not develop proprietary technology products. Its core offering is a membership-based service portfolio consisting of four membership tiers (Single, Multi, Value-Based Care Provider Group, Associate), two annual conferences plus boot camps and webinars, federal and state advocacy representation with CMS, CMMI, Congress and the White House, a Learning/Resources library including toolkits (e.g., Specialty Engagement Toolkit, April 2026), ACO comparison charts, data briefs, and ListServs for peer exchange. Distribution is direct: enrollment via naacos.com, conference registration, and the Partners Marketplace that connects 150+ business partners (Epic, Oracle, athenahealth, Arcadia, Innovaccer, Lightbeam, Health Catalyst, AstraZeneca, Eli Lilly, Sanofi, Quest Diagnostics, Labcorp, etc.) with alliance relationships to NCQA, AMA, ACP, Primary Care Collaborative, West Health Institute, and the Alzheimer's Association.

Revenue is generated through recurring 12-month membership dues (with 60-day pre-expiration renewal invoicing), conference and webinar registration fees, and a significant sponsorship/exhibitor stream under which business and alliance partners pay for recognition, exhibit space, and engagement with ACO buyers. The organization operates with a small professional staff (fewer than 20) and is governed by a Board of Directors composed of executives from member ACOs. In 2017 NAACOS seeded a separately incorporated affiliate, the Institute for Accountable Care, a 501(c)(3) research nonprofit. Leadership transitioned in 2025 from founding-era CEO Clif Gaus to Emily Brower (formerly SVP at Trinity Health and VP at Atrius Health).

Expansion highlights6 records

Direct peers

• AMGA (American Medical Group Association): Membership association for multispecialty medical groups and integrated delivery systems. Closely comparable to NAACOS as a healthcare trade association that advocates for value-based care, runs annual conferences, and offers peer learning, but its members are medical groups broadly rather than ACOs specifically.
• MGMA (Medical Group Management Association): Membership association serving medical practice leaders with education, data, and advocacy. Comparable as a healthcare membership organization using a similar dues-plus-conference revenue model and serving ACO-adjacent physician practices, though broader than ACOs.
• HFMA (Healthcare Financial Management Association): Membership association for healthcare finance professionals with education, certification, and advocacy. Comparable member-driven healthcare association with conferences, certifications, and policy work that overlaps with ACO financial leadership audiences served by NAACOS.
• CHIME (College of Healthcare Information Management Executives): Membership association for healthcare IT and informatics leaders. Comparable as a healthcare membership organization offering peer learning, events, and advocacy, serving CIOs who often lead ACO technology strategy within NAACOS member organizations.
• National Association of Community Health Centers (NACHC): Membership association for federally qualified health centers with policy advocacy and education. Comparable healthcare membership association model serving provider organizations participating in value-based-care programs that overlap with the ACO population NAACOS represents.

Broad incumbents

• AHA (American Hospital Association): Large national hospital and health system membership association with policy advocacy in Washington. Comparable as a healthcare advocacy organization representing many of the same institutional members as NAACOS, but operates across all hospital issues rather than ACO-specific value-based care.
• Premier Inc. Healthcare improvement alliance serving hospitals and health systems with group purchasing, analytics, and policy advocacy. Comparable as a value-based-care-focused enterprise serving overlapping ACO member organizations, but operates as a commercial company with deeper technology offerings.
• HIMSS (Healthcare Information and Management Systems Society): Large global healthcare technology membership association with annual conference and policy advocacy. Comparable member-driven model serving overlapping stakeholders with NAACOS partners (Epic, athenahealth, Oracle), but broader scope than ACO-specific value-based care.
• American Academy of Family Physicians (AAFP): Large physician membership association with advocacy and education. Comparable healthcare membership model serving primary care physicians who form the backbone of many NAACOS ACO members, but focused on a specialty rather than ACO delivery model.

Emerging players

• Aledade: ACO enablement company that operates a national network of physician-led ACOs and is a NAACOS member. Comparable as an active ACO ecosystem participant whose commercial interests intersect with NAACOS's advocacy agenda, but operates as a technology-enabled services company rather than a membership association.
