Background: Payment by Results is the means by which patient care is remunerated within the National Health Service. This relies on accurate clinical coding to allow appropriate billing and remuneration. We performed an audit of our coding accuracy and completed several audit loops to assess the associated long-term effect of changes that were implemented.
Methods: Case note review over four separate time periods between 2009 and 2014 at Nottingham University Hospitals NHS Trust.
Results: Coding accuracy improved from 67.7% to 86.7% across the four cycles. Loss of income was used as an outcome measure; this reduced from £339.61 per episode to £1.56 per episode over the four cycles.
Conclusions: We have shown a large and significant reduction in potential loss of income by implementing simple improvements to facilitate accurate coding.
