4.1 Social Determinants of Health

Why SDOH Belong in Screening and Assessment

Blueprint topic 1B5 expects the ACM candidate to assess financial, living situation, and support factors that shape a patient’s ability to follow the plan of care. Social determinants of health (SDOH)—also called social drivers of health—are the conditions in which people live, work, and age. In hospital case management, they are not “nice to know”; they are often the difference between a safe transition and a preventable return.

A patient may understand insulin teaching perfectly and still fail after discharge if there is no refrigerator, no money for supplies, or no ride to the clinic. Screening for clinical history without social context produces incomplete assessments and fragile discharge plans.

Core Domains for Hospital Case Management

Focus ACM screening on domains that most often block transitions:

Financial circumstances

Ask about income adequacy, ability to pay for medications and medical supplies, insurance gaps or high deductibles, and access to benefits (Medicaid, SNAP, SSI/SSDI, utility assistance). Financial strain predicts nonadherence, delayed follow-up, and early readmission. Document concrete barriers—for example, “cannot afford inhalers” or “uninsured for pharmacy”—not only a generic note that the patient is “low income.”

Living situation and housing

Assess where the patient will sleep after discharge, housing stability, crowding, utilities (heat, electricity, water), environmental hazards, and homelessness (sheltered or unsheltered). Living situation drives whether durable medical equipment can be used, whether wound care is feasible, and whether isolation precautions or infection control can be maintained at home.

Social support

Identify who helps with medications, transportation, meals, personal care, and decision-making. Note caregiver capacity, burnout, and availability after hours. Weak support elevates risk for patients with new mobility limits, cognitive impairment, or complex medication regimens—even when housing is adequate.

Related domains that frequently surface in the same conversation include food insecurity, transportation, employment disruption, education/literacy barriers, interpersonal safety, and legal circumstances (incarceration history, custody issues). Screen with trauma-informed language and privacy: social risk questions can feel stigmatizing if asked loudly at the bedside.

ICD-10-CM Z Codes (Z55–Z65) — Conceptual Use

ICD-10-CM categories Z55–Z65 cover “persons with potential health hazards related to socioeconomic and psychosocial circumstances.” Case managers do not need to memorize every subcode for the exam, but they must know the concept: these Z codes capture social risk so the organization can track needs, support risk adjustment and quality programs, and justify social interventions.

Common category map (conceptual):

• Z55 — Education and literacy problems
• Z56 — Employment and unemployment problems
• Z57 — Occupational exposure to risk factors
• Z58 — Problems related to the physical environment
• Z59 — Housing and economic circumstances (including homelessness, inadequate housing, food insecurity, extreme poverty, insufficient social insurance)
• Z60 — Problems related to social environment
• Z62 — Problems related to upbringing
• Z63 — Problems related to primary support group / family circumstances
• Z64 / Z65 — Other psychosocial circumstances (including certain legal issues and exposure to disaster/hostilities)

CMS guidance emphasizes that Z codes should be assigned when documentation specifies an associated problem or risk that influences health. Coding professionals may use documentation from social workers, community health workers, case managers, or nurses when the chart clearly describes the social factor. Screening alone is not enough—document the finding and its relevance to care.

On the ACM exam, expect items that distinguish Z codes (document social risk) from clinical diagnosis codes (document disease), and that recognize hospital CM’s role in capturing housing, food, money, and support problems that change the plan.

PRAPARE-Style Screening

PRAPARE (Protocol for Responding to and Assessing Patients’ Assets, Risks, and Experiences), developed through the National Association of Community Health Centers (NACHC) and partners, is a national standardized SDOH assessment. It is evidence-informed, available in many languages, and standardized to ICD-10, LOINC, and SNOMED so screening results can flow into the EHR and population analytics.

PRAPARE-style practice in hospitals typically includes:

1. Standard questions across housing, food, transportation, utilities, employment/income, education, safety, and social connection—so teams do not rely on ad hoc chat alone
2. Asset framing — identify strengths (supportive family, church, prior benefits) as well as risks
3. Response workflow — every positive screen needs a next step: resource list, referral, warm handoff, or documented patient decline
4. Timing — screen at admission/transition points when social barriers to discharge are still actionable; avoid waiting until the morning of discharge

Other validated tools (AHCM, Accountable Health Communities HRSN screening, Hunger Vital Sign, and health-system–specific EHR questionnaires) appear in practice. For ACM purposes, know that structured screening plus closed-loop referral beats informal “social history” alone.

How Hospital Case Managers Use SDOH Findings

Assessment without action fails patients and fails utilization goals. After a positive screen:

1. Prioritize barriers that block today’s discharge or next-day adherence — no home, no caregiver for IV antibiotics, empty pantry with a sodium-restricted diet, no ride to dialysis
2. Match interventions to the barrier — Continuum of Care / shelter resources and Housing First pathways for homelessness; pharmacy assistance and 340B/patient assistance programs for cost; medically tailored meals or pantry partners for food insecurity; non-emergency medical transportation or hospital ride programs for transport gaps
3. Coordinate across the IDT — nursing (teaching adjusted for literacy/housing), pharmacy (stable med forms that do not require refrigeration when possible), therapy (equipment feasible in the living environment), physicians (realistic disposition)
4. Document and code pathway — clear notes supporting Z-code capture; include who will follow the social need after discharge
5. Close the loop — confirm the community partner received the referral and the patient knows how to connect; “referred to food pantry” without a plan is incomplete CM work

Exam vignette pattern

A patient with heart failure is medically ready but has no electricity for a nebulizer and CPAP, cannot afford diuretics, and lives alone with no nearby family. The highest-yield CM move is to treat those SDOH findings as primary discharge barriers, not afterthoughts—secure a safe living arrangement or temporary placement, address medication access, and arrange support or home health before calling the patient “disposition complete.”

Key Distinctions for the ACM

• SDOH screening identifies risks; case management intervention remediates or mitigates them
• Z55–Z65 document social circumstances; they do not replace clinical diagnoses or justify inpatient status by themselves
• Financial, living, and support domains are the 1B5 core—other social risks matter, but exam items often hinge on money, housing, and who will help at home
• Structured tools such as PRAPARE improve reliability, coding linkage, and equity of screening across populations
