Aortic anatomy lesson helps keep your coding on the straight and narrow.
An important element of abdominal aortic aneurysm (AAA) coding is knowing whether the aneurysm has ruptured. Here’s a quick look at diagnosis coding for unruptured AAA, which is a ballooning of the portion of the aorta located in the abdomen.
ICD-9 coding rules: Code 441.4 is appropriate for an unruptured aneurysm of the abdominal aorta. ICD-9 provides separate codes for a ruptured aneurysm (441.3) and for aortic aneurysms in other locations (such as 441.2, Thoracic aneurysm without rupture).
ICD-10 changes: Your ICD-10 options are almost identical to your ICD-9 options. Code I71.4 is appropriate for an unruptured aneurysm of the abdominal aorta. ICD-10 also provides separate codes for a ruptured [...]
