title: Coronary angioplasty under the prospective payment system: the need for a severity-adjusted payment scheme.
abstract: To evaluate the adequacy of Diagnosis Related Group prospective payment for percutaneous transluminal coronary angioplasty, the clinical characteristics, length of stay and hospital charges of all patients undergoing this procedure at Boston's Beth Israel Hospital during a 100 day period were examined. Of 113 such patients, the 61 patients in whom nonelective dilation was performed for unstable or postinfarction angina had a significantly greater length of stay and total hospital charge (10 +/- 6 days and $14,700 +/- $7,400, respectively) than did the 52 patients in whom elective dilation was performed (6 +/- 5 days and $8,500 +/- $7,700, respectively, p less than 0.0001). Under the current prospective payment system, however, these two groups of patients would have been placed in the same Diagnosis Related Group, and would have thus commanded equal institutional reimbursement. One potential revision of the payment system is presented to help to deal with this disparity.
