About coding renal artery aneurysm
The ICD-10-CM code for renal artery aneurysm is I72.2 (Aneurysm of renal artery).
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.
