About coding artery erosion
The ICD-10-CM code for artery erosion is I77.2 (Rupture of artery). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on I77.2.
Within I77 (other disorders of arteries and arterioles), I77.2 is specifically for rupture of artery. Related codes cover arteriovenous fistula, acquired (I77.0), stricture of artery (I77.1), 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.
Don't report I77.2 together with the conditions in its Excludes1 note: traumatic rupture of artery - see injury of blood vessel by body region.
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.
