Code Description

ICD-10 F55.0 is a billable code used to indicate a diagnosis of abuse of antacids.

Key Diagnostic Point:

Abuse of antacids refers to the excessive and inappropriate use of over-the-counter antacid medications, which are typically used to relieve symptoms of heartburn, indigestion, and gastroesophageal reflux disease (GERD). This condition can arise from underlying psychological issues, including anxiety or eating disorders, where individuals may misuse antacids to manage symptoms of discomfort associated with food intake or to control weight. The chronic use of antacids can lead to metabolic imbalances, such as electrolyte disturbances, and may mask serious gastrointestinal conditions. Patients may present with symptoms such as abdominal pain, diarrhea, or constipation, which can complicate the clinical picture. The misuse of antacids can also be linked to behavioral syndromes, where the individual may develop a compulsive need to consume these medications, leading to further health complications. Proper diagnosis requires a thorough assessment of the patient's history, including dietary habits, psychological state, and any co-occurring disorders such as eating disorders or anxiety, which may contribute to the antacid abuse.
