Outcomes of aortic aneurysm surgery in England: a nationwide cohort study using hospital admissions data from 2002 to 2015

Table 22 OPCS codes for procedures used in combination with open OPCS codes to identify EVAR cases not coded with Table 14 codes of Appendix 2.

OPCS Code	OPCS Description
Y022	Insertion of prosthesis into organ NOC
Y532/Y782	Arteriotomy approach to organ using image guidance with computed tomography
Y532/Y783	Arteriotomy approach to organ using image guidance with ultrasound
Z341	Ascending aorta
Z342	Aortic arch
Z343	Descending thoracic aorta
Z344	Thoracic aorta NEC
Z345	Suprarenal abdominal aorta
Z346	Infrarenal abdominal aorta
Z347	Abdominal aorta NEC

The use of ‘insertion of prosthesis into organ NOC’ code alongside open AA repair code increased between 2002/03 and 2008/09, however this trend reversed between 2008/09 and 2014/15. Comparing the in-hospital mortality between the AA cases using ‘insertion of prosthesis” along the AA repair codes with open AA cases with open AA repair codes only; there is a clear difference between the two groups. The in-hospital mortality and percentage of elective for OPEN cases with the Y022 code before 2008/09 look like cases with the new EVAR codes. This observation is not present in the years after 2008/09.Based on this observation, the consensus group decided to classify open AA cases with the ‘insertion of prosthesis’ code as EVAR for the years before 2008/09.
