6.1 Social Determinants of Health (SDOH) & Community Resources
Key Takeaways
- Social Determinants of Health (SDOH) account for up to 80% of health outcomes, categorized under Healthy People 2030 into five core domains: Economic Stability, Education Access & Quality, Healthcare Access & Quality, Neighborhood & Built Environment, and Social & Community Context.
- Standardized screening tools like the PRAPARE instrument enable systematic collection of SDOH data, which should be documented using ICD-10 Z-codes (Z55–Z65) to capture risk factors, trigger community referrals, and justify risk-adjusted reimbursement.
- Primary SDOH barriers—including food insecurity, housing instability, and transportation deficits—require targeted case management interventions such as SNAP enrollment, medical respite care, and Medicaid Non-Emergency Medical Transportation (NEMT).
- Area Agencies on Aging (AAA), authorized under Title III of the Older Americans Act (OAA), provide vital community-based support services for adults aged 60 and older, including home-delivered meals, caregiver assistance, and legal aid.
- Certified Case Managers must facilitate 'warm handoffs' and utilize closed-loop referral systems (e.g., 211, Findhelp) to confirm that community resource referrals result in documented service delivery.
6.1 Social Determinants of Health (SDOH) & Community Resources
Understanding Social Determinants of Health (SDOH)
Social Determinants of Health (SDOH) are the non-medical conditions in which people are born, grow, live, work, and age. According to the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), SDOH account for 30% to 55% of health outcomes, with some estimates indicating that social, environmental, and behavioral drivers collectively dictate up to 80% of overall health outcomes. For the Certified Case Manager (CCM), recognizing and addressing these underlying factors is essential to achieving sustainable clinical goals, reducing avoidable hospital readmissions, and promoting health equity.
Historically, clinical care models focused almost exclusively on pathophysiological interventions and patient compliance. Modern case management frameworks recognize that clinical compliance is frequently impossible when basic human needs remain unmet. A client diagnosed with type 2 diabetes cannot adhere to insulin therapy if they lack housing stability, electricity for insulin refrigeration, or sufficient funds to purchase nutritious food. Case managers serve as the crucial link between clinical treatment plans and non-clinical community resources.
The Five Healthy People 2030 SDOH Domains
The U.S. Department of Health and Human Services (HHS) Healthy People 2030 initiative organizes social determinants into five distinct domains. The CCM exam frequently tests the classification of client risk factors into these specific domains:
| SDOH Domain | Core Focus Areas | Common Case Management Risk Factors |
|---|---|---|
| Economic Stability | Poverty, employment, food security, housing stability | Unemployment, underemployment, medical debt, inability to afford copayments or prescriptions, homelessness. |
| Education Access & Quality | High school graduation, literacy, early childhood education | Low health literacy, limited English proficiency, inability to read prescription labels or discharge instructions. |
| Healthcare Access & Quality | Health insurance coverage, access to care, health literacy | Uninsured/underinsured status, lack of primary care provider, geographic shortage of specialists, cultural barriers. |
| Neighborhood & Built Environment | Housing quality, crime, environmental hazards, transportation | Substandard housing (lead, mold), lack of air conditioning/heating, living in a food desert, lack of reliable transit. |
| Social & Community Context | Social cohesion, discrimination, civic participation, workplace conditions | Social isolation, living alone without a caregiver, exposure to domestic violence, systemic racism or discrimination. |
Clinical Deep Dive: Domain Interconnections
SDOH domains rarely exist in isolation. A client experiencing Economic Stability issues (e.g., job loss) frequently suffers secondary effects in Healthcare Access (loss of employer-sponsored health insurance) and Neighborhood & Built Environment (inability to afford rent leading to housing displacement). Case managers must evaluate clients holistically rather than addressing isolated symptoms.
Screening & Documenting SDOH: PRAPARE & Z-Codes
The PRAPARE Screening Tool
To systematically identify social risks, case managers utilize validated screening instruments. The most widely implemented tool in community health and care management is the Protocol for Responding to and Assessing Patients' Assets, Risks, and Experiences (PRAPARE).
Developed by the National Association of Community Health Centers (NACHC), PRAPARE is a standardized, risk-adjusted tool consisting of 21 core questions divided into four sections:
- Personal Characteristics: Race, ethnicity, migrant status, veteran status, language.
- Family & Home: Housing status, housing stability, safety in current residence, number of dependents.
- Money & Resources: Income level, employment status, insurance status, ability to meet material needs (food, clothing, utilities, phone, medicine).
- Social & Emotional Health: Frequency of social contact, stress levels, incarceration history.
Case managers use PRAPARE data to tier client risk, customize care plans, and advocate for community-level resource development.
ICD-10 Z-Codes (Z55–Z65)
Documentation of SDOH in medical records and case management software is standardized through ICD-10-CM Z-codes (specifically categories Z55 to Z65). Proper Z-code capture is essential for clinical documentation, risk-adjusted reimbursement models (such as Hierarchical Condition Categories / HCCs used in Medicare Advantage), and Accountable Care Organization (ACO) quality reporting.
Key Z-codes for the CCM exam include:
- Z59.0: Homelessness (includes unsheltered, sheltered, and temporary doubling up).
- Z59.41: Food insecurity (inability to acquire adequate food due to financial constraint).
- Z59.81: Transportation insecurity (lack of safe, reliable, affordable transportation to healthcare services).
- Z59.1: Inadequate housing (structural defects, lack of running water or heating).
- Z60.2: Problems related to living alone (social isolation risks).
- Z55.0: Illiteracy and low-level literacy.
Exam Tip: CMS guidelines allow Z-codes to be assigned based on documentation from any member of the healthcare team, including registered nurse case managers, social workers, and community health workers—not exclusively physicians. Furthermore, self-reported patient information during screening is fully valid for Z-code assignment.
Addressing Primary Social Vulnerabilities
1. Food Insecurity
Food insecurity is defined as the disruption of food intake or eating patterns because of a lack of money and other resources. Chronic food insecurity is directly linked to poorly controlled diabetes, hypertension, and congestive heart failure.
Key community interventions coordinated by case managers:
- SNAP (Supplemental Nutrition Assistance Program): Federal assistance providing monthly funds via Electronic Benefit Transfer (EBT) cards for low-income individuals.
- WIC (Special Supplemental Nutrition Program for Women, Infants, and Children): Target assistance for pregnant, postpartum, and breastfeeding women, infants, and children up to age 5.
- Meals on Wheels: Home-delivered nutritious meals for homebound older adults (typically age 60+) who cannot prepare their own food.
- Medically Tailored Meals (MTM): Specialized home-delivered meal plans customized by registered dietitians for clients with complex chronic conditions (e.g., renal disease, heart failure).
- Emergency Food Pantries & Senior Farmers' Market Nutrition Programs (SFMNP).
2. Housing Instability & Homelessness
Housing is healthcare. Unhoused individuals experience higher rates of emergency department (ED) utilization, extended hospital stays, and early mortality.
Case management strategies for housing deficits:
- Supportive Housing / Housing First Models: Providing immediate, permanent housing without requiring clients to achieve sobriety or psychiatric stability prior to entry.
- HUD Section 8 Housing Choice Vouchers: Federal rental assistance programs for low-income families, elderly, and disabled individuals.
- Medical Respite Care (Recuperative Care): Acute and post-acute care for unhoused individuals who are too sick to stay on the street or in a traditional shelter but do not require inpatient hospitalization. Medical respite offers safe recuperation, wound care, medication administration, and case management linkage to permanent housing.
3. Transportation Barriers
Transportation insecurity causes missed medical appointments, delayed prescription pickups, and fragmented chronic disease management.
Case management solutions:
- Medicaid Non-Emergency Medical Transportation (NEMT): Mandatory benefit under federal Medicaid law requiring state Medicaid programs to provide transportation to covered medical appointments for eligible beneficiaries who lack their own transit.
- ADA Paratransit Services: Public transit services required by the Americans with Disabilities Act for individuals whose disability prevents them from using fixed-route bus or rail systems.
- Community Voucher Programs: Providing rideshare (e.g., Uber Health, Lyft Pass), taxi vouchers, or public transit passes funded through grant programs or hospital charity care.
Community Resource Coordination & Area Agencies on Aging (AAA)
Area Agencies on Aging (AAA)
Established under Title III of the Older Americans Act (OAA) of 1965, Area Agencies on Aging (AAAs) are public or private non-profit agencies designated by states to address the needs and foster the independence of older adults (aged 60 and older).
AAAs coordinate a comprehensive network of local services, including:
- Information and Assistance (I&A) / Information and Referral (I&R).
- Nutrition Services: Congregate meal sites and Meals on Wheels.
- Family Caregiver Support Programs (Title III-E): Respite care, caregiver training, and counseling.
- In-Home Personal Care & Homemaker Services.
- Health Promotion & Disease Prevention: Evidence-based fall prevention and chronic disease self-management classes.
- Long-Term Care Ombudsman Program: Investigating complaints and advocating for residents in nursing homes and assisted living facilities.
- Legal Assistance: Support for elder rights, guardianship defense, advance directives, and public benefit appeals.
211 Systems & Closed-Loop Referral Platforms
Effective resource coordination requires moving beyond passive referrals (giving a client a phone number) to active, closed-loop referrals.
- 2-1-1 Referral Network: Free, confidential national telephone and web service connecting individuals to local health and human service resources.
- Closed-Loop Technology Platforms (e.g., Findhelp/Aunt Bertha, Unite Us): Software integrated with electronic health records (EHRs) that allows case managers to send electronic referrals directly to community-based organizations (CBOs) and track whether the service was received.

Clinical Scenario & Exam Traps
Clinical Scenario
A 68-year-old male with severe heart failure and type 2 diabetes is readmitted to the acute care hospital for the third time in 60 days with acute fluid overload and severe hyperglycemia. During the initial case management interview, the client admits that he ran out of money for food two weeks ago and has been eating low-cost canned soups (high sodium) provided by a neighbor. Additionally, he lost his electricity last week due to unpaid utility bills, causing his stored insulin to spoil.
- Assessment: The client's readmission is driven primarily by Economic Stability and Neighborhood/Built Environment SDOH factors (food insecurity Z59.41, utility insecurity Z59.8), not lack of clinical knowledge.
- Case Management Plan:
- Arrange immediate utility restoration assistance through the Low-Income Home Energy Assistance Program (LIHEAP).
- Secure replacement insulin through pharmaceutical manufacturer assistance programs or emergency hospital foundation funds.
- Coordinate daily medically tailored, low-sodium meals through the local Area Agency on Aging (AAA).
- Submit an EBT application for SNAP benefits.
- Document ICD-10 Z-codes in the discharge summary to reflect social complexity.
Exam Traps to Avoid
- The "Educational Reflex" Trap: Selecting a case management action that re-educates the client on diet or medication compliance when the root cause is financial or environmental impossibility. Always address the underlying SDOH barrier first.
- The "Passive Referral" Trap: Assuming that providing a pamphlet or telephone number completes the case manager's duty. The exam favors options reflecting active coordination, warm handoffs, and follow-up confirmation.
- Age Requirements for AAA: Believing AAA services require Medicaid eligibility or age 65+. OAA Title III services are open to all individuals aged 60 and older, regardless of income (though services prioritize low-income and minority elders).
A case manager completes a PRAPARE screening for a newly discharged patient with hypertension.
