K55 Vascular disorders of intestine
ICD-10-CM category K55 sits in Chapter 11 (Diseases of the digestive system, K00-K95). It contains 27 billable codes for FY2027, effective October 1, 2026 to September 30, 2027. Always code to the most specific code available: a code with more characters that describes the diagnosis more precisely takes priority over a shorter one.
