2025 ICD-10-CM code K55.1
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Diseases of the digestive system - Other diseases of intestines Diseases of the digestive system Feed
Chronic vascular disorders of the intestine, encompassing conditions like chronic ischemic colitis, enteritis, enterocolitis, ischemic stricture, mesenteric atherosclerosis, and mesenteric vascular insufficiency.
ICD-10 codes do not utilize modifiers. Modifiers are used with CPT and HCPCS codes.
Medical necessity for treatment of K55.1 will vary depending on the severity of symptoms and presence of complications.Procedures should be supported by appropriate clinical findings and documented according to payer guidelines.Severe symptoms (e.g., bowel obstruction, perforation, bleeding) necessitate urgent intervention.
The clinical responsibility for patients with K55.1 will depend on the specific presentation and associated complications.Typically, gastroenterologists, vascular surgeons, or internists manage these patients.Diagnosis and management will often involve imaging studies, such as CT angiography, and potentially surgical intervention.
In simple words: This code describes long-term problems with blood flow to the intestines.It covers conditions where the arteries supplying the intestines are narrowed or hardened, leading to inflammation or narrowing of the intestines.
K55.1, Chronic vascular disorders of intestine, in the ICD-10-CM classification, groups several chronic conditions affecting the intestinal vasculature.These include chronic ischemic colitis (inflammation of the colon due to reduced blood flow), chronic ischemic enteritis (inflammation of the small intestine due to reduced blood flow), chronic ischemic enterocolitis (affecting both small and large intestines), ischemic stricture of the intestine (narrowing due to ischemia), mesenteric atherosclerosis (hardening of arteries supplying the intestines), and mesenteric vascular insufficiency (inadequate blood supply to the mesentery). The code excludes conditions such as necrotizing enterocolitis of the newborn (P77.-).
Example 1: A 72-year-old male patient presents with abdominal pain, weight loss, and bloody stools. Colonoscopy reveals evidence of chronic ischemic colitis. The diagnosis is coded as K55.1., A 65-year-old female patient with a history of atherosclerosis experiences recurrent bouts of abdominal cramping and diarrhea.Angiography demonstrates significant narrowing of the mesenteric arteries.K55.1 is coded., A 80-year-old patient undergoes surgery for intestinal obstruction secondary to chronic mesenteric ischemia.Post-operative diagnosis is K55.1, with additional codes reflecting the surgical procedure and any postoperative complications.
Complete medical history including risk factors for vascular disease (e.g., diabetes, hypertension, smoking);Physical examination findings; Imaging studies (e.g., CT angiography, Doppler ultrasound, mesenteric angiography);Endoscopy reports if performed;Pathology results if a biopsy was performed;Treatment notes;Hospital discharge summaries.
** The severity of chronic vascular disorders of the intestine can vary greatly.Always consider the patient's clinical presentation when selecting the appropriate ICD-10 code and other supporting codes. Accurate documentation is crucial for appropriate reimbursement.
- Revenue Code: Revenue codes will vary depending on the specific services provided and the payer. Consult your payer's guidelines for appropriate revenue code selection.
