Using blinded techniques with reliability checks, medical-record specialists reabstracted International...

Hospital reimbursement by Medicare's prospective payment system depends on accurate identification and coding of inpatients' diagnoses procedures using the International Classification Diseases, Ninth Revision, Clinical Modification (ICD-9-CM).

This DRG "creep" improperly increased net 1.9%, +308 million...
