Angiodysplasia of colon with hemorrhage
ICD-10 K55.21 is a billable code used to indicate a diagnosis of angiodysplasia of colon with hemorrhage.
Angiodysplasia of the colon with hemorrhage is a vascular malformation characterized by abnormal blood vessels in the colon that can lead to gastrointestinal bleeding. Clinically, patients may present with symptoms such as hematochezia (bright red blood in stool), melena (dark, tarry stools), or anemia due to chronic blood loss. The condition primarily affects the right colon and is often associated with aging, although it can occur in younger individuals as well. The anatomy involved includes the colonic mucosa and submucosa where these vascular lesions are located. Disease progression can vary; some patients may experience intermittent bleeding, while others may have significant hemorrhage requiring medical intervention. Diagnostic considerations include colonoscopy, which allows for direct visualization of the lesions, and may also involve imaging studies such as CT angiography to assess the extent of vascular involvement. Biopsy is typically avoided due to the risk of bleeding. Management may include endoscopic interventions, such as cauterization or band ligation, and in severe cases, surgical resection may be necessary.

K55.21 specifically covers angiodysplasia of the colon that is associated with hemorrhage. This includes cases where patients present with gastrointestinal bleeding attributed to vascular malformations in the colonic mucosa.
K55.21 should be used when there is clear documentation of angiodysplasia with active or recent hemorrhage. If there is no bleeding or if the bleeding is due to another cause, other codes such as K55.20 should be considered.
Documentation should include clinical notes detailing the patient's symptoms, results of diagnostic imaging and endoscopy, treatment interventions, and any follow-up care related to the management of the hemorrhage.
