A
ACA
GovernmentFederal law expanding health insurance and creating online marketplaces where individuals shop for coverage. Provides premium tax credits and cost-sharing reductions based on income, prohibits denial for pre-existing conditions.
Accident Insurance
InsuranceSupplemental insurance that pays benefits if the policyholder is injured in a covered accident. Pays a lump sum or scheduled benefits for accidents resulting in emergency room visits, hospitalization, fractures, or other specified injuries.
Activities of Daily Living
Long-Term CareBasic self-care tasks used to assess functional ability and determine need for assistance. Six standard ADLs: bathing, dressing, toileting, transferring, continence, feeding. Inability to perform ADLs independently triggers long-term care needs. Used for insurance eligibility, facility placement, care planning.
Actuarial Value
InsuranceThe percentage of total average costs for covered benefits that a health plan pays. Bronze plans have 60% actuarial value, Silver 70%, Gold 80%, and Platinum 90%. The remaining percentage is what consumers pay through deductibles, copayments, and coinsurance.
Addison's Disease
DiseasesRare disorder where adrenal glands do not produce enough cortisol and often aldosterone. Symptoms develop slowly: fatigue, muscle weakness, weight loss, low blood pressure, skin darkening. Life-threatening adrenal crisis can occur with stress. Requires lifelong hormone replacement therapy.

Three presentations: predominantly inattentive, predominantly hyperactive-impulsive, or combined. Affects children and adults, impacting academic, occupational, and social functioning.
Adult Day Care
Long-Term CareSupervised program providing social activities, meals, recreation, some health services during daytime hours. Allows caregivers to work or get respite while participants receive care and socialization. May be social model or medical model. Often private pay, sometimes Medicaid or Veterans benefits.

Affordability Test
InsuranceUnder the employer mandate, coverage is considered affordable if the employee s share of self-only premium for the lowest-cost plan does not exceed 9.12% (2023) of household income. If coverage is unaffordable, the employee may qualify for marketplace premium tax credits.
Age Rating
InsuranceThe practice of charging different premiums based on age. Under the ACA, insurers can charge older adults up to 3 times more than younger adults (3:1 ratio). Some states impose stricter limits on age rating.
Aggregate Deductible
InsuranceA family plan structure where the entire family deductible must be met before insurance begins cost-sharing for any family member. All family members' expenses count toward the single family deductible amount.
