In brief
Multicenter study of 99 NEC patients reveals 59% of exploratory abdominal operations were coded inaccurately, with CPT codes failing to capture critical details like mucous fistula creation, ostomy type, or bowel length resected. These coding inadequacies significantly limit the reliability of database research in pediatric surgery.
Written by the GCMD Library team from the article.
Introduction
The ability to use detailed, accurate current procedural terminology (CPT) codes is a key component of effective research. We examined the effectiveness of CPT codes to accurately reflect care in patients undergoing surgery for necrotizing enterocolitis (NEC).
Methods
A multicenter retrospective analysis of operations on patients with NEC was conducted across 4 institutions between 2011 and 2016. Correlation between operative dictation and CPT coding was analyzed.
Results
A total of 124 patients with NEC diagnosis undergoing exploratory abdominal operations were identified. NEC was improperly diagnosed in 25 patients, who were excluded from further analysis. Of the 99 patients reviewed, the initial exploratory abdominal operation was coded inaccurately in 58 cases (59%). Within these, 15 (26%) had multiple coding errors such that the nature of the original operation was not discernable from the applied codes. Inaccurate codes often did not describe the presence of a mucous fistula (n=27, 44%), ostomy (n=24, 39%), or extra segments of bowel resected (n=9, 16%). The length of bowel resected is not currently described by any CPT codes.
Conclusion
CPT coding for abdominal operations does not sufficiently reflect complexity of pediatric surgeries. This study highlights the significance of this inadequacy and its implications in future database studies in the era of electronic medical records.
