About I72.2

I72.2 is the ICD-10-CM diagnosis code for aneurysm of renal artery. It belongs to category I72 (other aneurysm), block I70-I79 (diseases of arteries, arterioles and capillaries) and chapter 9 (diseases of the circulatory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within I72 (other aneurysm), I72.2 is specifically for aneurysm of renal artery. Related codes cover carotid artery (I72.0), artery of upper extremity (I72.1), iliac artery (I72.3), artery of lower extremity (I72.4), other precerebral arteries (I72.5), vertebral artery (I72.6), other specified arteries (I72.8) and unspecified site (I72.9).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 698 (Other Kidney and Urinary Tract Diagnoses with MCC, relative weight 1.6398), DRG 699 (Other Kidney and Urinary Tract Diagnoses with CC, relative weight 1.0003) and DRG 700 (Other Kidney and Urinary Tract Diagnoses without CC/MCC, relative weight 0.6741), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 442.1 (aneurysm of renal artery).
