Pica in adults

This code signifies the persistent, compulsive consumption of non-nutritive, non-food substances (e.g., dirt, clay, ice, hair, paint chips) by an adult. This behavior is not culturally sanctioned and is severe enough to warrant clinical attention, often leading to medical complications.

Apply this code when an adult patient (typically over 18 years of age) presents with documented pica that is not attributable to a developmental stage or intellectual disability. Documentation should clearly indicate the ingestion of non-food items and the patient's age.

• Ensure the patient's age is clearly documented as adult to differentiate from pediatric pica.
• Code any associated medical complications (e.g., lead poisoning, intestinal obstruction, dental damage) separately.
• Do not use this code if the pica is due to a nutritional deficiency (e.g., iron deficiency anemia causing pagophagia), as the underlying deficiency would be the primary diagnosis.
