ICD-10 Code F50.83 – Pica in adults (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F50.83 – Pica in adults
What it is
Use this code for pica in adults, an eating disorder marked by persistent craving and consumption of nonfood, nonnutritive substances. The behavior must be inappropriate for the person’s developmental level and not culturally accepted.
Clinical signs
Typical findings include repeated ingestion of items such as dirt, paper, clay, hair, or ice. Clinical features vary; refer to documentation, and confirm that the behavior has persisted long enough to meet diagnostic criteria.
When to use this code
Assign F50.83 when the record clearly documents pica in an adult patient and the provider identifies it as the diagnosis. Use it when the chart describes ongoing ingestion of nonfood substances rather than a one-time accidental swallow. If the note does not specify pica, check documentation.
Do not use for
Do not use this code for childhood pica, which is coded separately, or for accidental ingestion without a diagnosed eating disorder. Do not use it when the substance use is intentional for another reason, such as substance abuse or cultural practice.
Coding tip
Verify the provider documents pica in an adult and distinguish it from accidental ingestion or other eating disorders before assigning F50.83.
