About coding artery obliteration
The ICD-10-CM code for artery obliteration is I77.1 (Stricture of artery).
Within I77 (other disorders of arteries and arterioles), I77.1 is specifically for stricture of artery. Related codes cover arteriovenous fistula, acquired (I77.0), rupture of artery (I77.2), arterial fibromuscular dysplasia (I77.3), celiac artery compression syndrome (I77.4), necrosis of artery (I77.5), arteritis, unspecified (I77.6), other arterial dissection (I77.7), other specified disorders of arteries and arterioles (I77.8) and 1 more.
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 299 (Peripheral Vascular Disorders with MCC, relative weight 1.5842), DRG 300 (Peripheral Vascular Disorders with CC, relative weight 1.0464) and DRG 301 (Peripheral Vascular Disorders without CC/MCC, relative weight 0.7133), in MDC 05 (Diseases and Disorders of the Circulatory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
