About ICD-9-CM 557.0

557.0 is an ICD-9-CM diagnosis code for acute vascular insufficiency of intestine. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.

The CMS General Equivalence Mappings translate it to 22 ICD-10-CM codes, such as K55.011 (Focal (segmental) acute (reversible) ischemia of small intestine), K55.012 (Diffuse acute (reversible) ischemia of small intestine) and K55.019 (Acute (reversible) ischemia of small intestine, extent unspecified). All of these are approximate matches, so review the record to pick the right one.
