We would like to present this service evaluation of Taylor Spatial Frame use within a busy limb reconstruction unit. We present a cohort of 60 patients representing a year of work from January 2011 to January 2012 with a breakdown of coding data. Included are details of operative episodes, length of stay, outpatient follow up including software programming episodes, strut changes and general frame care from our specialist nurses. We have produced a comparison of cost to HRG coding tarifs with an audit of coding errors and cost implications of these corrections. Also included is a breakdown of comparison data from patients undergoing frame assisted deformity correction and internal fixation, Computer Hexapod Assisted Orthopaedic Surgery. Exact and careful coding of these procedures is required considering their relatively high cost.
