Patient presents with intermittent symptoms consistent with mild persistent asthma.  The patient reports episodic wheezing, shortness of breath (dyspnea), and chest tightness, particularly during exercise or exposure to allergens such as dust mites and pollen.  These asthma attacks are typically infrequent, occurring less than twice per week, and nighttime awakenings due to asthma symptoms are reported less than twice per month.  Lung function tests, including spirometry with FEV1 and FVC measurements, demonstrate mild airflow limitation with FEV1 greater than 80% predicted and a normal FEV1FVC ratio.  Symptoms are well-controlled with as-needed use of a short-acting beta-agonist (SABA) inhaler, such as albuterol.  Patient education regarding asthma management, including trigger avoidance, proper inhaler technique, and asthma action plan development, was provided.  Diagnosis of mild persistent asthma is confirmed based on symptom frequency, lung function, and response to therapy.  Patient advised to continue current treatment regimen and follow up for reassessment as needed.  ICD-10 code J45.21 (Mild intermittent asthma) is assigned for billing purposes.  Medical necessity for prescribed medications and patient education is documented.
