Patient presents with a history of asthma, characterized by recurrent episodes of wheezing, shortness of breath, chest tightness, and cough.  Onset of symptoms initially occurred during childhood.  Patient reports intermittent exacerbations triggered by various factors including allergens such as dust mites, pet dander, and pollen, as well as environmental irritants like smoke and strong odors.  Viral respiratory infections also frequently precipitate asthma attacks.  Patient denies any current symptoms.  Pulmonary function testing performed previously demonstrated reversible airway obstruction, confirming the diagnosis of asthma.  Current medications include an albuterol inhaler as needed for acute symptoms.  The patient understands the importance of asthma management, including trigger avoidance and proper inhaler technique.  Assessment includes chronic asthma, well-controlled.  Plan includes continuing current medication regimen, patient education regarding asthma triggers and management, and follow-up for reassessment of asthma control and medication efficacy.  Differential diagnoses considered included bronchitis, allergic rhinitis, and chronic obstructive pulmonary disease.  ICD-10 code J45.90, Unspecified asthma, is assigned.
