F45.9 is a billable ICD code used to specify a diagnosis of somatoform disorder, unspecified. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code F45 is used to code Multiple chemical sensitivity

Multiple chemical sensitivity (MCS) or idiopathic environmental intolerances (IEI) is a chronic medical condition and syndrome characterized by symptoms that the affected person attributes to low-level chemical exposures to commonly used chemicals. Commonly attributed substances include scented products, pesticides, plastics, synthetic fabrics, smoke, petroleum products, and paint fumes. Symptoms are subjective and vague. Symptoms are also non-specific, meaning that they are common symptoms, such as fatigue or headaches, that are present in hundreds of other illnesses. Commonly reported symptoms also include nausea, dizziness, and inflammation of skin, joints, gastrointestinal tract and airways.
