They iclude bathig or showerig, dressig, gettig i ad out of bed or a chair, usig the toilet, ad eatig. If a sample perso had ay difficulty performig a activity by himself/ herself ad without special equipmet, or did ot perform the activity at all because of health problems, the perso was deemed to have a limitatio i that activity. The limitatio may have bee temporary or chroic at the time of the survey. Sample persos who were admiistered a commuity iterview aswered health status ad fuctioig questios themselves, uless they were uable to do so. A proxy, such as a urse, always aswered questios about the sample perso s health status ad fuctioig for log-term care facility iterviews. Arthritis: The category arthritis icludes rheumatoid arthritis, osteoarthritis, ad other forms of arthritis. Aual rate of chage: The aual rates of chage i Tables 6.1 to 6.16 refer to average aual growth rates. The growth rate from oe year to the ext is the ratio of the figure for the secod year to the figure for the first year, mius 1. The growth rate over a 2-year period is the square root of the ratio of the figure for the third year to the figure for the first year, mius 1. The growth rate over a 3-year period is the cube root of the ratio of the figure for the fourth year to the figure for the first year, mius 1, ad so o. For example, the figure for aual rate of chage from 1992 to 1995 is calculated as follows: the figure for 1995 is divided by the figure for 1992, ad the the cube root of the result is calculated. This figure mius 1 is the average aual growth from 1992 to 1995: 3 1995 / 1992 1. Similarly, the formula used to calculate the average aual growth rate from 1992 to 2005 is: 13 2005 / 1992 1. The aual growth rate from 2004 to 2005 is calculated as follows: (2005 / 2004) 1. The result is the multiplied by 100 to give the percetage preseted i the table. It is ot possible to calculate stadard errors for the growth rates. Balace billig: I the Medicare program, the practice of billig a Medicare beeficiary i excess of Medicare s allowed charge is kow as balace billig. The balace billig amout is the differece betwee Medicare s allowed charge ad the provider s actual charge to the patiet.

Sample persos with limitatios i at least oe IADL, but o ADL, were icluded i the category IADL oly. Sample persos with ADL limitatios were categorized by the umber of limitatios (1 to 2, 3 to 5) regardless of the presece or umber of IADL limitatios. Sample persos who were admiistered a commuity iterview aswered questios about their fuctioal limitatios themselves, uless they were uable to do so. A proxy, such as a urse, always aswered questios about the sample perso s fuctioal limitatios for log-term care facility iterviews. Health maiteace orgaizatio (HMO): A HMO provides, or arrages for the provisio of, a comprehesive package of health care services to erolled persos for a fixed capitatio paymet (see cap itatio paymet).

HCPPs are paid by Medicare o a reasoable cost basis to provide Part B services to Medicare erollees. Health status: A sample perso was asked to rate his or her geeral health compared to other people of the same age. Sample persos who were admiistered a commuity iterview aswered health status questios themselves, uless they were uable to do so. A proxy, such as a urse, always aswered questios about the sample perso s health status for log-term care facility iterviews.

Sample persos who were admiistered a commuity iterview aswered health status ad fuctioig questios themselves, uless they were uable to do so. A proxy, such as a urse, always aswered questios about the sample perso s health status ad fuctioig for log-term care facility iterviews. Facility iterviewers did ot ask about the sample perso s ability to prepare meals or perform light or heavy housework, sice they are ot applicable to the sample perso s situatio; however, iterviewers did questio proxies about the sample perso s ability to maage moey, shop for groceries or persoal items, or use a telephoe. Isurace coverage: Isurace categories were derived from aual isurace coverage variables i the 2005 Cost ad Use files. The aual variables idicate whether a sample perso held that type of isurace at some poit durig 2005. Isurace categories i this sourcebook were costructed to be mutually exclusive by prioritizig isurace holdigs. Medicaid coverage had the highest priority; i.e., if a sample perso was eligible for Medicaid beefits at some poit durig 2005, the perso was icluded i the Medicaid category, regardless of other isurace holdigs durig the year. Erollmet i a Medicare HMO had the secod-highest priority, after Medicaid eligibility. Other public health isurace plas, icludig Veteras Admiistratio eligibility or a State-sposored drug pla, are distributed across the isurace categories accordig to the sample perso s highest-priority isurace coverage. For example, a perso eligible for Medicaid coverage who was also eligible for a State-sposored drug pla is categorized uder Medicaid. The categories defied below apply to commuity residets. Facility residets have oly four isurace categories: Medicare fee-for-serviceoly, Medicaid, private isurace, ad Medicare HMO.

For beeficiaries who resided i a log-term care facility for part of the year ad i the commuity for part of the year, commuity isurace status is show. Both types of private isurace ecompasses sample persos eligible for Part A ad/or Part B Medicare beefits, ad who had both employer-sposored private isurace ad self-purchased private isurace, but who did ot have Medicaid or Medicare HMO coverage at ay poit durig 2005. Medicare fee-for-service-oly ecompasses sample persos eligible for Part A ad/or Part B Medicare beefits, ad who did ot have Medicaid coverage, private isurace, ad who were ot erolled i a private or Medicare HMO at ay time durig 2005. However, sample persos may have had other public isurace coverage, such as a State-sposored prescriptio drug pla, or may have bee eligible for Veteras Admiistratio health care beefits. Medicaid ecompasses sample persos eligible for Part A ad/or Part B Medicare beefits, ad who were eligible for State Medicaid beefits at some poit durig 2005, regardless of the perso s other isurace holdigs. Idividually-purchased private isurace ecompasses sample persos eligible for Part A ad/or Part B Medicare beefits, ad who had self-purchased private isurace plas ( Medigap isurace), but did ot have Medicaid, private or Medicare HMO, or employer-sposored private isurace coverage at ay poit durig 2005. Employer-sposored private isurace ecompasses sample persos eligible for Part A ad/or Part B Medicare beefits, ad who had employer-purchased private isurace plas, but did ot have Medicaid, Medicare HMO, or self-purchased private isurace coverage at ay poit durig 2005. Sample persos erolled i private HMOs, who did ot have Medicaid or Medicare HMO coverage at ay poit durig 2005, are also icluded i this category. Medicare HMO ecompasses sample persos erolled i ay type of Medicare HMO, who were ot eligible for Medicaid beefits at ay poit durig 2005. The category icludes beeficiaries erolled i Medicare risk HMOs, Medicare cost HMOs, ad health care prepaymet plas (see health maiteace orgaizatio). Livig arragemet: For commuity residets, sample persos were separated ito mutually exclusive categories: 1) beeficiary lives aloe, 2) beeficiary lives with a spouse oly, or lives with a spouse ad other relatives or orelatives, 3) beeficiary lives with his or her childre, or lives with his or her childre ad other relatives or orelatives, but does ot live with a spouse, or 4) beeficiary lives with other relatives or orelatives, but ot with his or her childre or a spouse.

Log-term care facility: The basic uit measurig use of facility services is a stay i a log-term care facility. Stays are measured i terms of days of residece i that facility. If the beeficiary was still i the facility at the ed of the year, the stay is ot complete, but all data for 2005 are preset. To qualify for the survey, a log-term care facility must have three or more log-term care beds, ad provide either persoal care services to residets, provide cotiuous supervisio of residets, or provide log-term care services throughout the facility or i a separately idetifiable uit.

If oted i foototes, log-term care facility use ad expeditures i this sourcebook iclude short-term facility stays (istitutioal evets), primarily i skilled ursig facilities, that were reported either durig a commuity iterview or created through Medicare claims data. Istitutioal evets are icluded i the 2005 cost ad use files if the discharge date for the stay was i 2005. Medicare home health services: Home health care services are arrowly defied i the MCBS public use files. Home health care is limited to skilled ursig services ad other therapeutic services provided by a Medicare participatig home health agecy. I the MCBS, home health use represets evets where medical care, as opposed to persoal care ad support, was furished to the sample perso. Medicare pays 100 percet of the approved cost of covered home health visits, ad 80 percet of the approved cost of durable medical equipmet. Medicare hospice services: Hospice services are arrowly defied i the MCBS public use files. Hospice care is limited to Medicarecovered services for termially ill idividuals who have elected to receive hospice care rather tha stadard Medicare beefits. Hospice services iclude medical, ursig, couselig, ad other supportive services redered to termially ill people ad their families. Hospice care is iteded to be palliative ad to improve quality of life rather tha to cure disease or exted life. Almost all services provided to the hospice beeficiary are fully covered by Medicare. Two exceptios are prescribed medicies ad ipatiet respite care. These two types of services require a small amout of copaymet. Metal illesses/disorders: The category metal illesses/disorders icludes metal retardatio, depressio, ad other metal disorders. This defiitio was expaded to iclude metal retardatio, schizophreia, ad maic depressio for facility residets i 1997; ad it was further expaded to iclude depressio for commuity residets i 2000. Missig values: Whe amouts (e.g., beeficiary couts or expeditures per beeficiary) are displayed i a table i this sourcebook, sample persos with missig resposes or who belog to a category of a variable ot show i the table (e.g., other for the variable race/ ethicity ) are excluded from idividual categories displayed, but are icluded i the total. Whe colum or row percetages are displayed i a table, sample persos with missig resposes are assumed to be distributed the same as reported data ad are icluded i the percetages. That is, colum or row percetages sum to 100 percet of the colum or row total. Mobility limitatio: If the sample perso had o difficulty at all walkig a quarter of a mile, the respose was coded as o. If the sample perso had a little, some, or a lot of difficulty, or could ot walk a quarter of a mile, the respose was coded as yes. The respose reflects whether the sample perso usually had trouble walkig, rather tha temporary difficulty, such as from a short-term ijury. Sample persos who were admiistered a commuity iterview aswered health status ad fuctioig questios themselves, uless they were uable to do so. A proxy, such as a urse, always aswered questios about the sample perso s health status ad fuctioig for log-term care facility iterviews. Appedix B Defiitios of Terms ad Variables B-6
Health & Health Care of the Medicare Populatio: 2005 Outpatiet hospital services: For a survey-reported evet, the basic uit measurig use of outpatiet services is a separate visit to ay part of a outpatiet departmet or outpatiet cliic at a hospital. For Medicare claim-oly evets, it may represet 1) a sigle visit; 2) multiple procedures or services withi oe visit; or 3) multiple visits billed together. Outpatiet hospital evets iclude emergecy room visits that did ot result i a ipatiet hospital admissio. Persoal health care expeditures: Persoal health care expeditures cosist of health care goods ad services purchased directly by idividuals. They exclude public program admiistratio costs, the et cost of private health isurace, research by oprofit groups ad govermet etities, ad the value of ew costructio put i place for hospitals ad ursig homes. Total persoal health care expeditures i this source-book equal the sum of expeditures by Medicare, Medicaid, private isurace, out-of-pocket, ad other sources, as defied below. Log-term care facility expeditures iclude expeditures for short-term facility stays (istitutioal evets), primarily i skilled ursig facilities, that were reported durig a commuity iterview or created through Medicare claims data as oted i foototes. Medicare expeditures equal Medicare program paymets for fee-for-service beeficiaries, aual capitatio paymets to Medicare HMOs o behalf of erollees, 1 ad pass-through expeses for ipatiet hospital services (see defiitio below). They exclude reported or imputed charges for idividual evets reported by Medicare HMO erollees. Capitatio paymets were allocated across medical service types i the same proportios as Medicare fee-for-service paymets for medical service types. Medicare expeditures for ipatiet hospital services iclude pass-through expeses. Medicare s Prospective Paymet System (PPS) for ipatiet hospital services pays a fixed, predetermied amout per case. However, this paymet excludes some hospital expeses, particularly for capital costs, that are reimbursed o a cost basis (i.e., capital costs are passed through for paymet). I order to calculate total Medicare program paymets (actual PPS case paymet plus the prorated share of pass-through costs), estimated pass-through costs were added to charges for ipatiet hospital evets. Medicare expeditures for log-term care services cosist of paymets made by Medicare to log-term care facilities for skilled ursig or skilled rehabilitatio services that are ot icluded i ay of the other evet records. Medicaid expeditures cosist of paymets for services made by State Medicaid programs.

For facility residets, private isurace expeditures cosist of paymets made by private health isurace plas, whose sources (i.e., idividual purchase or employersposored) are ukow. No distictio was made durig the collectio of the facility data as to the source of private health isurace plas. 1 I this sourcebook, the followig chages were made i calculatig total Medicare HMO expeditures: a) admiistrative cost (about 10 percet of the total aual Medicare HMO capitated paymets) was subtracted from the total aual Medicare HMO capitated paymets; ad b) aual Medicare HMO premiums were added to the total aual Medicare HMO capitated paymets.

Other source expeditures cosist of paymets made by other public health plas ad private liability isurace plas. For sample persos who resided i the commuity, examples of other public sources of paymet iclude State pharmaceutical assistace programs ad paymets for sample persos who received medical services from the Veteras Admiistratio. For sample persos who resided i a log-term care facility, examples of other public sources of paymet iclude paymets from State, couty, or commuity departmets of metal health, State supplemetal assistace ad welfare programs, ad Black Lug fuds.
