D8940 - A condition where certain immune cells (mast cells) become overactive and release chemicals that cause allergic-like symptoms
International Classification of Diseases
What is a ICD-10 Code?
ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.
Detailed Description
Mast cell activation syndrome is a condition where mast cells, which are immune system cells that normally help protect your body, become overactive and release too many chemicals like histamine. This can cause symptoms similar to allergic reactions, such as flushing, itching, hives, digestive problems, fatigue, and sometimes more serious reactions. The 'unspecified' designation means the exact type or cause of the mast cell activation hasn't been determined yet. This diagnosis often requires specialized testing and may need management by specialists who understand this complex condition.
Additional Information
This is a complex condition that often requires ongoing management and may take time to diagnose properly. Symptoms can vary widely between patients and may be triggered by various factors including stress, certain foods, medications, or environmental factors.
