K55.1 is a billable ICD code used to specify a diagnosis of chronic vascular disorders of intestine. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)

557.1
Chronic vascular insufficiency of intestine (exact match)

This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 557.1 was previously used, K55.1 is the appropriate modern ICD10 code.
