Surgical CPT Coding Discrepancies: Analysis of Surgeons and Employed Coders.

Surgeon providers and billing professionals use Current Procedural Terminology (CPT) codes to specify patient treatment and associated charges. In the present study, coding discrepancies between surgeons' first pass coding and employed coders' final codes were investigated. A total of 500 patients over 3 months were retrospectively analyzed for coding discrepancies. To quantify the impact of change, codes with the most accumulated discrepancies were studied and change to annual relative value unit (RVU) was determined. Final submission of codes to billing demonstrated a 161% increase in total codes by the professional coders, versus original surgeon-derived codes (1594 vs 987 CPT codes). The most common source of change between the surgeon and coder was the addition of distinct codes by the billing professional (270 patients, 54.51%). These results demonstrate the existence of coding discrepancies. Future investigation will evaluate the communication between surgeons and billing professionals.

Impact of Reduced Preincision Antibiotic Infusion Time on Surgical Site Infection Rates: A Retrospective Cohort Study.

OBJECTIVE: Our objective was to determine the impact of total preincision infusion time on surgical site infections (SSIs) and establish an optimal time threshold for subsequent prospective study. BACKGROUND: SSIs remain a major cause of morbidity. Although regulated, the total time of infusion of preincision antibiotics varies widely. Impact of infusion time on SSI risk is poorly understood. METHODS: All consecutive patients (n = 46,791) undergoing inpatient surgical intervention were retrospectively enrolled (2014-2015) and monitored for 1 year. Primary outcomes: the presence of SSI infection as predicted by reduced preoperative antibiotic infusion time. SECONDARY OUTCOMES: preintervention compliance, the impact of a quality improvement algorithm to optimize infusion time compliance. Multivariate logistic regression of the retrospective cohort demonstrated predictors of infection. Receiver-operating characteristic analysis demonstrated the timing threshold predictive of infection. Cost impact of avoidable infections was analyzed. RESULTS: Only 36.1% of patients received preincision infusion of vancomycin in compliance with national and institutional standards (60-120 min). Cephalosporin infusion times were 53 times more likely to be compliant [odds ratio (OR) 53.33, P < 0.001]. Vancomycin infusion times that were not compliant with national standards (less than standard 60-120 min) did not predict infection. However, significantly noncompliant, reduced preincision infusion time, significantly predicted SSI (<24.6 min infusion, AUC = 0.762). Vancomycin infusion, initiated too close to surgical incision, predicted increased SSI (OR = 4.281, P < 0.001). Implementation of an algorithm to improve infusion time, but not powered to demonstrate infection /reduction, improved vancomycin infusion start time (257% improvement, P < 0.001) and eliminated high-risk infusions (sub-24.6 min). CONCLUSIONS: Initially, vancomycin infusion rarely met national guidelines; however, minimal compliance breach was not associated with SSI implications. The retrospective data here suggest a critical infusion time for infection reduction (24.6 min before incision). Prospective implementation of an algorithm led to 100% compliance. These data suggest that vancomycin administration timing should be studied prospectively.
