Abstract
Purpose: To review the existing practice of coding in spinal surgery and ascertain its accuracy for surgical procedures, co-morbidities and complications.
Methods: A retrospective review of 70 cervical and 100 lumbar consecutive spinal surgeries performed since April 2006 was conducted. The clinical coding data and hospital notes were reviewed.
Results: Coding data of 5 cervical spine surgeries were not available. Of the 165 cases, the accuracy of primary procedural codes was 93.9% (90.8% cervical & 96% lumbar). This reduced to 77.6% (75.4% cervical & 79% lumbar) when the accuracy for entire description of performed surgery was considered. Medical co-morbidities were coded appropriately in 64.2% of the patients (55% cervical & 70% lumbar). The procedural codes did not specifically reflect the surgery performed and lacked reproducibility. Surgical levels were coded incorrectly in 9% of the cases. Cervical surgeries were coded as lumbar in 4 and posterior surgery as anterior in 3 cases respectively. The commonly missed co-morbidities were drug allergies, hypercholesterolemia, smoking and alcoholism. Post-op adverse events were coded in 75% of the cases (16/20 cervical & 5/8 lumbar). The accuracy was better for lumbar as compared to cervical spinal surgeries.
Conclusion: Coding is a universal language of communication and its accuracy is important not just for PbR, but for data quality, audit and research purposes too. The financial implications regarding PbR governed by HRG codes (dictated by OPCS 4.4 & ICD–10 codes) are discussed. Following this study, a clinical coding facilitation form has been introduced to improve data quality.
