In 1950 the US Public Health Service and the Veterans Administration began independent tests of ICD-6 for hospital indexing purposes. In 1951 the Presbyterian Hospital in New York City adopted the ICD-6th Revision with some modifications for use in its record department (HCFA,1980) 8 Copyright © 2010 Raymond R.

6 ICD History The Ninth revision in 1975 in Geneva included procedures in medicine and of impairments, and handicaps. ICD-9-CM became effective in January 1979 and is currently up to its latest revision to keep up with new technologies, procedures, and diseases. Over the past century, ICD was under the control of WHO, The Commission on Professional Hospital Activity and currently the Health Care Financing Administration (HCFA), and Centers for Medicare and Medicaid (CMS) ICD-10-CM was released in 1999 and will be required for physician and hospital use in 2013 and currently is optional as of December 2009 9 Definitions A classification of disease may be defined as a system of categories to which morbid entities are assigned according to established criteria. A Statistical classification of diseases must encompass the entire range of morbid conditions within a manageable number of categories (ICD-10, WHO,1992) 10 Copyright © 2010 Raymond R.

Lecture 10
19 Introduction Medicare and Medicaid were adopted in 1965. Since their adoption and for the past 45 years the expenses for these federal funded programs have been uncontrollable. Many methods were attempted to reduce their annual growth. The most radical occurred in 1980 with the passage of public law PL-98-21 known as the Prospective Payment System (PPS). It mandated that hospitals rates were to be announces the prior year before they went into effect and rather than pay by a patients length of stay, payment would be by the diagnoses treated. 35 What Presidential Administration? DRG Design A system developed at Yale known as the diagnosis-related grouping system (DRG) was used as it currently is today, 29 years later. The patient variables to be used in the construction of the Diagnosis-related grouping system would consist of the information routinely collected by hospital in its current data collection and abstraction systems. These included diagnosis and procedure codes, death, age, and the existence of complications and comorbidities (CC). The system had as its goal the creation of a manageable number of DRGs to which payments would be assigned. Using the ICD-9- CM coding system was ruled out due to it having thousands of diagnoses and procedures. 36 Copyright © 2010 Raymond R. Arons, Teaneck, NJ, USA
20.
Lecture 10
20 DRG History 1978 - HCFA funded an experiment with eighteen New Jersey hospitals having 383 DRGs as a prospective payment system. The ICD-8 coding system was used to construct the DRGs. 1979 - The ICD-9-CM based DRGs were funded for development at Yale School of Organization and Management. 1980 - Publication of the methodology used to construct the DRGs at Yale: Fetter R, Shin Y, Freeman RF, Averill R, Thomson JD.(1980) Case mix definitions by diagnosis-related groupings Medical Care, 18 (2, Supplement pp1-53). 37 continued... DRG History 1982 - All New Jersey hospitals used the DRGs for all discharges including Medicare, Medicaid and all private payors using a DRG system with 430 categories. 1983 – In 1980 public law PL-98-21 was passed known as the Prospective Payment System (PPS). 2010 – The DRGs are into their 28th version and are used for all Medicare discharges and applied as a classification system for all discharge abstracts.. 38 continued...

Lecture 10
21 DRG History DRGs have been exported to France and a number of the European 8 nations. The DRG system is designed by a division of 3M which has been involved in its design since its inception. New York State uses a Non-Medicare Grouper for its younger patients. It has more categories such as: – The DRG 500 Series (Major Complications) – The DRG 600 Series (Neonates) – The DRG 700 Series (HIV) – The DRG 800 Series (TB) 39 Grouping Systems A grouper is a statistical program that takes the billing claims submitted to Medicare and places them into similar clinical and resource intense groupings. Each group is assigned a relative weight based on the mean charges submitted yearly. The results are reweighing the diagnosis-related groupings (DRGs) and the basis for rates of reimbursement for following year. In addition new DRGs are created based upon the use of new technologies that are considered standards of practice. . 40 continued... Copyright © 2010 Raymond R. Arons, Teaneck, NJ, USA

Lecture 10
22 Grouping Systems Therefore in September of each year CMS will produce a list of new adopted Medicare DRGs with estimated payments for the upcoming fiscal year The DRGs are divided into surgical or medical treatments The principal diagnosis is “the condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital for care.” The principal procedure “performed for definitive treatment rather than diagnostic or exploratory purposes, or that was necessary to treat a complication. The principal procedure is usually related to the principal diagnosis.” 41 continued... Grouping Systems Complication or comorbidity (CC) are defined as: – A complication is a condition that arises during the hospital stay that prolongs the length of stay one- day in approximately 75 percent of the cases. – A comorbidity is a pre-existing conditions that because of its presence with a specific diagnosis causes an increase length of stay by at least one- day in approximately 42 Copyright © 2010 Raymond R.

23 Definitions Medicare DRGs Non-Medicare DRGs 43 Major Diagnostic Categories (MDC) Diagnosis-related groupings have also been divided into categories that follow the body systems and function as a means to group DRGs. They are as follows: MDC 1 Diseases and Disorders of the Nervous System MDC 2 Diseases and Disorders of the Eye MDC 3 Diseases and Disorders of the Ear, Nose &Throat MDC 4 Diseases and Disorders of the Respiratory System MDC 5 Diseases and Disorders of the Circulatory System MDC 6 Diseases and Disorders of the Digestive System 44 continued...
