Other specified noninfective gastroenteritis and colitis

This code represents inflammatory conditions of the stomach and intestines that are not caused by an infection and do not fit into more specific categories. It encompasses various non-infectious etiologies leading to gastrointestinal inflammation, such as allergic reactions, drug-induced enterocolitis, or other idiopathic forms of gastroenteritis or colitis.

Use this code when documentation clearly indicates a non-infectious cause for gastroenteritis or colitis that is not otherwise specified or classifiable to a more precise K52 subcategory. This includes conditions like eosinophilic gastroenteritis, microscopic colitis not specified as collagenous or lymphocytic, or drug-induced enterocolitis where the specific drug is not the primary diagnosis. Supporting documentation should detail the non-infectious nature and the specific type of gastroenteritis or colitis if known, or rule out infectious causes.

• Ensure infectious causes (e.g., bacterial, viral, parasitic) have been ruled out or are not the primary diagnosis.
• Avoid using this code if a more specific non-infectious gastroenteritis or colitis code (e.g., K52.2 for allergic and dietetic) is available and supported by documentation.
• Always review the medical record for any identified causative agents (e.g., drugs, food allergens) that might warrant an additional code to fully describe the patient's condition.
