Patient presents with symptoms suggestive of mold exposure, including allergic rhinitis, cough, wheezing, dyspnea, headache, fatigue, sinusitis, and eye irritation.  Onset of symptoms correlated with reported exposure to visible mold growth or damp, musty environments at home or work.  Differential diagnosis includes other respiratory illnesses such as viral upper respiratory infection, asthma exacerbation, and bacterial pneumonia.  Physical examination reveals watery eyes, nasal congestion, and possible auscultatory findings such as wheezing or rales.  No fever noted.  Patient denies smoking history.  Assessment includes consideration of environmental risk factors for mold exposure, such as water damage, poor ventilation, and high humidity.  Diagnosis of mold exposure is based on symptom presentation, reported exposure history, and clinical findings.  Laboratory testing, such as IgE antibody testing or environmental mold sampling, may be considered for confirmation or to identify specific mold species.  Treatment plan includes avoidance of mold exposure, symptomatic management with antihistamines, decongestants, and bronchodilators as needed, and potential referral to an allergist or immunologist for further evaluation and management of mold allergy. Patient education provided regarding mold remediation strategies and prevention of future exposure.  Follow-up recommended to assess symptom resolution and adjust treatment plan as necessary.  ICD-10 code T78.4 (Other specified adverse effects not elsewhere classified) and related codes for specific symptoms, such as J30.1 (Allergic rhinitis due to pollen) or J45.991 (Unspecified asthma, uncomplicated), may be applicable.  CPT codes for evaluation and management services, allergy testing, and pulmonary function tests may also be considered based on the provided services.
