AbstractDiagnosis-related group (DRG) codes for burn injuries are defined by thresholds of the percentage of total body surface area and depth of burns, and by whether surgery, debridement, or grafting or both occurred. This prospective study was designed to determine whether periodic revisions of the burn diagram resulted in more accurate assignment of the International Classification of Diseases and DRG codes. The admission burn diagrams were revised after admission and after each surgical procedure. All areas grafted (deep second-and third-degree burns) were diagrammed as "third-degree," after the current convention that both are biologically the same and require grafting. The multiple diagrams from 82 charts were analyzed to determine the disparities in the percentage of total body surface area burn and the percentage of body surface area third-degree burn. The revised diagrams differed from the admission diagrams in 96.5% of the cases. In 77% of the cases, the revised diagram correctly depicted the percentage of body surface area third-degree burn as confirmed intraoperatively. In 7.3% of the cases, diagram revision changed the DRG code. Documenting wound evolution in this manner allows more accurate assignment of the International Classification of Diseases and DRG codes, assuring optimal reimbursement under the prospective payment system.
