Celiac disease

This code represents celiac disease, an autoimmune disorder characterized by an adverse reaction to gluten, leading to damage in the small intestine. This damage impairs nutrient absorption and can result in a variety of gastrointestinal and systemic symptoms.

Use this code when documentation confirms a diagnosis of celiac disease, often supported by positive serological tests (e.g., anti-tissue transglutaminase antibodies) and/or small bowel biopsy showing villous atrophy. It is appropriate for both initial diagnoses and ongoing management of the condition.

• Differentiate from other malabsorption syndromes or food intolerances; celiac disease requires specific diagnostic criteria.
• Consider any associated nutritional deficiencies (e.g., iron deficiency anemia, osteoporosis) and code them separately as secondary diagnoses.
• Ensure documentation clearly states "celiac disease" rather than just "gluten intolerance" unless further diagnostic workup confirms celiac.
