The following are terms likely to be useful as health care reform continues.

A B C D E F G H I J K L M N O P Q U-Z

Academic Medical Center: A group of related institutions including a teaching hospital or hospitals, a medical school and its affiliated faculty practice plan, and other health professional schools. (PPRC, 1997)
Access: The ability to obtain needed health care services. (PPRC, 1997)
Accountable Health Plan (AHP): A plan that would offer a nationally defined package of specified benefits and provide consumers with a report card on the quality and services offered by the plan.
Accountable Health Partnership: An organization of doctors and hospitals which provides care for people organized into large groups of purchasers.
Accounting Perspectives (Evaluation): Perspectives underlying decisions on which categories of goods and services to include as costs or benefits in an analysis. (Rossi and Freeman, 1993)
Activities of Daily Living (ADL): An index or scale that measures an individual's degree of independence in bathing, dressing, using the toilet, eating, and moving across a small room. (MedPAC, 1998)
Activity-based Costing (ABC): Activity-based costing defines costs in terms of an organization's processes or activities and determines costs associated with significant activities or events. ABC relies on the following three step process: Activity mapping, which involves mapping activities in an illustrated sequence; Activity analysis, which involves defining and assigning a time value to activities; and Bill of activities, which involves generating a cost for each main activity. (Canby, 1995)
Activity-based Management (ABM): Activity-based Management...supports operations by focusing on the causes of costs and how costs can be reduced. It assesses cost drivers that directly affect the cost of a product or service, and uses performance measures to evaluate the financial or nonfinancial benefit an activity provides. By identifying each cost driver and assessing the value the element adds to the healthcare enterprise, ABM provides a basis for selecting areas that can be changed to reduce costs. (Player, 1998)
Adjusted Admissions: A measure of all patient care activity undertaken in a hospital, both inpatient and outpatient. Adjusted admissions are equivalent to the sum of inpatient admissions and an estimate of the volume of outpatient services. This estimate is calculated by multiplying outpatient visits by the ratio of outpatient charges per visit to inpatient charges per admission. (AHA and ProPAC, 1996)
Adjusted Average Per Capita Cost (AAPCC): (1) Actuarial projections of per capita Medicare spending for enrollees in fee-for-service Medicare. Separate AAPCCs are calculated - usually at the county level - for Part A services and Part B services for the aged, disabled, and people with ESRD. Medicare pays risk plans by applying adjustment factors to 95 percent of the Part A and Part B AAPCCs. The adjustment factors reflect differences in Medicare per capita fee-for-service spending related to age, sex, institutional status, Medicaid status, and employment status. (ProPAC, 1996)
Adjusted Community Rate (ACR): Estimated payment rates that health plans with Medicare risk contracts would have received for their Medicare enrollees if paid their private market premiums, adjusted for differences in benefit packages and service use. Health plans estimate their ACRs annually and adjust subsequent year supplemental benefits or premiums to return any excess Medicare revenue above the ACR to enrollees. See Adjusted Average Per Capita Cost, Medicare Risk Contract. (PPRC, 1996)
Adjusted Community Rate (ACR) Proposal: A process by which a health plan contracting with Medicare estimates the cost of providing services to its Medicare enrolles based on costs and revenues from its commercial business. Health plans estimate their ACRs annually and adjust the subsequent year's supplemental benefits or premiums offered so that they do not receive a higher rate of return on Medicare enrollees than they do on their commercial business. (MedPAC, 1998)
Adjusted Payment Rate (APR): The Medicare capitated payment to risk-contract HMOs. For a given plan, the APR is determined by adjusting county-level AAPCCs to reflect the relative risks of the plan's enrollees. See Adjusted Average Per Capita Cost. (PPRC, 1996)
Adjusted Community Rate (ACR) Proposal: A process by which a health plan with a Medicare risk contract estimates the cost of providing services to its Medicare enrollees based on costs and revenues from its commercial business. Health plans estimate their ACRs annually and adjust the subse quent year's supplemental benefits or premiums offered so that they do not receive a higher rate of return on Medicare enrollees than they do on their commercial business. See Adjusted Average Per Capita Cost, Medicare Risk Contract. (PCRP, 1997)

Plans with a subpopulation with higher than average costs are adversely selected. Plans with a subpopulation with lower than average costs are favorably selected.(MedPAC, 1998)
Age-at-Issuance Rating: A method for establishing health insurance premiums whereby an insurer's premium is based on the age of individuals when they first purchased health insurance coverage. (PPRC, 1996)
Age-Attained Rating: A method for establishing health insurance premiums whereby an insurer's premium is based on the current age of the beneficiary. Age-attained-rated premiums increase as the purchaser grows older.(PPRC, 1996)
Aggregate Margin: A margin that compares revenues to expenses for a group of hospitals, rather than a single hospital. It is computed by subtracting the sum of expenses for all hospitals in the group from the sum of revenues and dividing by the sum of revenues. (See also PPS Inpatient Margin, PPS Operating, Margin, and Total Margin.) (MedPAC, 1998)
Aggregate PPS Operating Margin/Aggregate Total Margin: A PPS operating margin or total margin that compare revenue to expenses for a group of hospitals, rather than a single hospital. It is computed by subtracting the sum of expenses for all hospitals in the group from the sum of revenues and dividing by the sum of revenues. (See also PPS Operating Margin and Total Margin.) (ProPAC)
Aid to Families with Dependent Children (AFDC) program: A program established by the Social Security Act of 1935 and eliminated by welfare reform legislation in 1996. AFDC provided cash payments to needy children (and their caretakers) who lacked support because at least one parent was unavailable. Families had to meet income and resource criteria specified by the state to be eligible. AFDC has been replaced by a new block grant program, but AFDC standards are retained for use in Medicaid. See Temporary Assistance for Needy Families. (PPRC, 1997)

(HCFA)
Assessment: The regular collection, analysis and sharing of information about health conditions, risks, and resources in a community. The assessment function is needed to identify trends in illness, injury, and death, the factors which may cause these events, available health resources and their application, unmet needs, and community perceptions about health issues. (PHIP, 1996)
Assignment: A process under which Medicare pays its share of the allowed charge directly to the physician or supplier. Medicare will do this only if the physician accepts Medicare's allowed charge as payment in full (guarantees not to balance bill). Medicare provides other incentives to physicians who accept assignment for all patients under the Participating Physician and Supplier Program. See Balance Billing, Nonparticipating Physicians, Participating Physician, Participating Physician and Supplier Program. (MedPAC, 1998)

Basic DRG Payment Rate: The payment rate a hospital will receive for a Medicare patient in a particular diagnosis-related group.

(Inefficiencies in consumption can occur when health services are inappropriately utilized; inefficiencies in allocation exist when health services could be delivered in less costly settings without loss of quality; and, inefficiencies in production exist when the costs of producing health services could be reduced by using a different combination of resources.) (Source, 1994)

Such coverage generally leaves the beneficiary responsible for the employer's plan's cost sharing and deductibles. (PPRC,1996)
Exclusions: Populations or services can be ecxluded from a mainstream managed care plan, and reimbursed on a fee-for-service basis. An exclusion generally employed if mainstream plans are unwilling to enroll high cost individuals or if a system of care does not exist to serve this population, because either their disease is rare or their rural or remote location prohibits the formation of a managed care network. (State. 1997)
