In simple words: This code describes inflammation in the left side of the large intestine that's causing a blockage.The blockage prevents normal bowel movements and needs medical attention.

This code signifies left-sided colitis (inflammation of the left colon) with the added complication of intestinal obstruction.The obstruction refers to a blockage in the bowel preventing the normal passage of stool. This condition requires careful clinical management due to the potential for serious consequences such as perforation and peritonitis.

Example 1: A 60-year-old female patient presents with severe abdominal pain, distension, vomiting, and constipation for 2 days.Physical examination reveals tenderness in the left lower quadrant.Imaging studies (CT scan) confirm left-sided colitis with significant colonic distension and evidence of a complete obstruction.The patient undergoes surgical intervention to relieve the obstruction and address the colitis., A 45-year-old male patient with a known history of ulcerative colitis experiences a sudden onset of severe abdominal pain and constipation.His previous treatment was well-managed, but this time, he is unable to pass gas or stool.Sigmoidoscopy reveals severe left-sided inflammation and luminal narrowing, causing an obstruction.He is treated medically with bowel rest, nasogastric tube decompression, and intravenous fluids, with close monitoring for surgical intervention if the obstruction doesn't resolve., A 72-year-old patient with a longstanding history of ulcerative colitis develops a gradual worsening of symptoms.He experiences intermittent abdominal cramping and reduced bowel movements over several weeks.Colon examination shows significant inflammation and stricture formation in the left colon, leading to partial obstruction. The patient is initially managed medically with anti-inflammatory medications and dietary modifications but eventually requires surgical intervention due to persisting symptoms and worsening obstruction.

Comprehensive documentation should include a detailed history of present illness, past medical history (especially focusing on inflammatory bowel disease), physical examination findings, relevant imaging studies (such as abdominal X-ray, CT scan, or MRI), endoscopy reports (colonoscopy, sigmoidoscopy), and laboratory results (complete blood count, electrolytes, inflammatory markers).The documentation must clearly establish the presence of both left-sided colitis and intestinal obstruction, specifying the nature and severity of each.

** Accurate coding requires comprehensive clinical documentation that clearly defines the presence of both left-sided colitis and intestinal obstruction, and specifies their severity.Consider additional codes to capture comorbidities and other relevant clinical findings.
