In support of this mandate, HCFA has been collecting inpatient encounter data from health plans since 1997. These data include diagnoses and other information that can be used to identify chronic medical problems that contribute to higher costs, so that health plans can be paid more when they care for sicker patients. In this article, the authors describe the risk-adjustment model HCFA is implementing in the year 2000, known as the Principal Inpatient Diagnostic Cost Group (PIPDCG) model.en-USAdolescentAdultAgedCapitation FeeCenters for Medicare and Medicaid Services (U.S.)ChildChild, PreschoolDemographyDiagnosis-Related GroupsFemaleHumansInfantInfant, NewbornMaleMedicaidMedicare Part CMiddle Aged*Models, EconometricRisk AdjustmentUnited StatesBiostatisticsEpidemiologyHealth Services ResearchPrincipal inpatient diagnostic cost group model for Medicare risk adjustmentJournal Articlehttps://escholarship.umassmed.edu/cgi/viewcontent.cgi?article=1696&context=qhs_pp&unstamped=1https://escholarship.umassmed.edu/qhs_pp/6961378842qhs_pp/696
