Intestinal malabsorption, unspecified

This code signifies a general failure of the small intestine to adequately absorb nutrients from digested food. It encompasses a broad range of conditions where the body cannot properly take in fats, proteins, carbohydrates, vitamins, or minerals. The underlying cause of the malabsorption is not specified or known.

Use this code when documentation indicates intestinal malabsorption without further specificity regarding its etiology or type. This is appropriate when the provider has diagnosed malabsorption but has not identified the specific disease process (e.g., celiac disease, Crohn's disease, pancreatic insufficiency) causing it. Supporting documentation would include physician notes stating "intestinal malabsorption" without additional detail.

• Avoid using this code if a more specific diagnosis for malabsorption is documented (e.g., K90.0 for Celiac disease).
• Always query the provider for a more specific diagnosis if possible, as unspecified codes often impact reimbursement and data quality.
• Consider sequencing this code after any associated symptoms (e.g., diarrhea, weight loss) if the malabsorption is the definitive diagnosis.
