Vascular disorders of intestine
Medical necessity is established by the presence of signs, symptoms, and/or diagnostic findings that indicate a vascular disorder of the intestine. The documentation should clearly support the need for the diagnostic and therapeutic interventions performed.
Diagnosis and management of vascular disorders of the intestine typically falls under gastroenterologists, surgeons, and interventional radiologists, depending on the specific condition and treatment required.
In simple words: Problems with the blood vessels supplying the intestines.
Vascular disorders of intestine
Example 1: A patient presents with sudden onset of severe abdominal pain, bloody diarrhea, and a history of atrial fibrillation. Imaging reveals a blockage in the mesenteric artery, leading to a diagnosis of acute mesenteric ischemia (K55.0)., A patient with a history of peripheral artery disease experiences chronic abdominal pain after meals, weight loss, and fear of eating.Angiography shows narrowing of the mesenteric arteries, consistent with chronic mesenteric ischemia (K55.1)., A patient undergoes a colonoscopy which reveals areas of angiodysplasia (abnormal blood vessels) in the colon, causing intermittent bleeding. This can be classified under K55 (though more specific codes might exist depending on location and severity.)
Documentation should include details of the patient's symptoms (e.g., abdominal pain, diarrhea, bleeding), medical history (e.g., cardiovascular disease, prior surgeries), diagnostic tests (e.g., imaging studies, endoscopic findings), and treatment provided.
