(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Noninfective enteritis and colitis - Left sided colitis with complications Diseases of the digestive system (K00-K95) Feed
Left-sided colitis with fistula.
Modifiers may be applicable depending on the circumstances of the procedure or service, such as location or type of service.
Medical necessity is established by the presence of symptoms consistent with colitis (abdominal pain, diarrhea, weight loss, bleeding) and confirmation via colonoscopy or other imaging.The presence of a fistula indicates a more complex condition requiring intervention to prevent further complications.
Diagnosis and management of left-sided colitis and any associated fistula. This may involve clinical examination, imaging studies (colonoscopy, CT scan), and treatment depending on the severity and symptoms.
In simple words: This code describes inflammation in the left side of the large intestine (colon) that has resulted in an abnormal connection or passageway to another organ or the body's surface.
This ICD-10-CM code signifies left-sided colitis complicated by the presence of a fistula.A fistula is an abnormal connection between two organs or between an organ and the body surface. In this context, it indicates an abnormal connection associated with the inflammation of the left side of the colon.
Example 1: A 60-year-old female presents with chronic abdominal pain, bloody diarrhea, and weight loss. Colonoscopy reveals left-sided colitis with a fistula connecting the colon to the bladder., A 45-year-old male with a history of ulcerative colitis experiences worsening symptoms, including fever and localized abdominal tenderness.Imaging confirms a left-sided colitis with a perianal fistula., A 72-year-old patient undergoes a colonoscopy to investigate chronic diarrhea. The procedure reveals left-sided colitis and a fistula between the colon and a nearby structure requiring surgical intervention.
Complete history and physical examination focusing on gastrointestinal symptoms.Detailed documentation of colonoscopy findings including location, extent, and characteristics of colitis.Radiological imaging (e.g., CT scan, MRI) to visualize the fistula and assess its extent.Laboratory results, such as complete blood count (CBC), stool studies, and inflammatory markers.
** This code is typically used in conjunction with other codes to fully capture the patient's condition and treatment.It's crucial to differentiate this code from other colitis codes based on location and the presence of complications like fistulas, abscesses, or intestinal obstruction.
