ICD Code J45.20

ICD code J45.20 is a classification used to identify mild intermittent asthma without any complications. This code is part of the International Classification of Diseases (ICD) system, which is used by healthcare providers to document and categorize medical diagnoses. Mild intermittent asthma refers to a form of asthma where symptoms occur infrequently, typically less than twice a week, and do not interfere significantly with daily activities. The "uncomplicated" designation indicates that there are no additional complications or conditions associated with the asthma diagnosis.

1. Presence of Asthma Symptoms: The patient exhibits symptoms consistent with asthma, such as wheezing, shortness of breath, chest tightness, or coughing, particularly at night or early in the morning.

2. Intermittent Occurrence: Symptoms occur less than twice a week, and nighttime awakenings due to asthma symptoms occur less than twice a month.

3. Normal Lung Function: Between episodes, the patient's lung function tests, such as spirometry, show normal results, indicating no persistent airway obstruction.

4. No Impact on Daily Activities: The asthma symptoms do not interfere with the patient's normal daily activities or exercise.

5. No Exacerbations Requiring Systemic Corticosteroids: The patient has not experienced any exacerbations that necessitate the use of systemic corticosteroids in the past year.

6. Absence of Complications: There are no complications or additional conditions that exacerbate or complicate the asthma, such as respiratory infections or other chronic respiratory diseases.

7. Positive Response to Treatment: The patient responds well to short-acting beta-agonists (SABAs) or other quick-relief medications, with symptoms resolving quickly after use.

8. No Requirement for Long-term Control Medication: The patient does not require daily long-term control medication to manage symptoms effectively.
