Collagenous colitis
ICD-10 K52.831 is a billable code used to indicate a diagnosis of collagenous colitis.
Collagenous colitis is a type of microscopic colitis characterized by chronic, non-bacterial diarrhea and inflammation of the colon. It primarily affects the mucosal layer of the colon, where collagen deposition occurs, leading to symptoms such as watery diarrhea, abdominal pain, and weight loss. The exact etiology remains unclear, but it is believed to involve immune-mediated mechanisms, dietary factors, and possibly genetic predispositions. The disease progression can vary; some patients may experience intermittent symptoms, while others may have persistent diarrhea. Diagnosis typically involves a colonoscopy with biopsy to confirm the presence of collagenous deposits in the colonic mucosa. Patients may also undergo stool tests to rule out infections or other gastrointestinal disorders. Treatment often includes dietary modifications, anti-diarrheal medications, and in some cases, corticosteroids to reduce inflammation. Regular follow-up is essential to monitor symptoms and adjust treatment as necessary.

K52.831 specifically covers collagenous colitis, which is characterized by chronic diarrhea and histological findings of collagen deposition in the colon. It is distinct from other forms of colitis, such as lymphocytic colitis or ulcerative colitis.
K52.831 should be used when a patient presents with symptoms consistent with collagenous colitis, confirmed by biopsy showing collagenous deposits. It should not be used for other types of colitis without specific histological findings.
Documentation for K52.831 should include a detailed clinical history, symptom description, results of colonoscopy and biopsy, and any treatments attempted. Clear evidence of collagen deposition in the colonic mucosa is essential for accurate coding.
