This month, we are focusing on aortic aneurysms.
Patients diagnosed with an aneurysm may not need surgical intervention right away but could be defined clinically as “under surveillance” for an active aneurysm. The diagnosis code should reflect the active condition code from series I71.1–I71.9.
Types of aortic aneurysms specified in ICD-10-CM include:
- Thoracic aortic aneurysm
- Abdominal aortic aneurysm
- Thoracoabdominal aneurysm
Below is the listing of ICD-10 codes for reporting aortic aneurysms (notice location and rupture vs. without rupture are defined by the code):
|I71.1||Thoracic aortic aneurysm, ruptured|
|I71.2||Thoracic aortic aneurysm, without rupture|
|I71.3||Abdominal aortic aneurysm, ruptured|
|I71.4||Abdominal aortic aneurysm, without rupture|
|I71.5||Thoracoabdominal aortic aneurysm, ruptured|
|I71.6||Thoracoabdominal aortic aneurysm, without rupture|
|I71.8||Aortic aneurysm of unspecified site, ruptured|
|I71.9||Aortic aneurysm of unspecified site, without rupture|
ICD-10 code Z86.79: Report personal history of other diseases of the circulatory system if an aneurysm has been surgically repaired.
