About coding Leriche's syndrome
The ICD-10-CM code for Leriche's syndrome is I74.09 (Other arterial embolism and thrombosis of abdominal aorta).
Within I74.0, choose I74.09 (Other arterial embolism and thrombosis of abdominal aorta) only when documentation doesn't support a more specific option: saddle embolus of abdominal aorta (I74.01).
Code first: embolism and thrombosis complicating abortion or ectopic or molar pregnancy (O00-O07, O08.2) and embolism and thrombosis complicating pregnancy, childbirth and the puerperium (O88.-).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
