Mild persistent asthma with (acute) exacerbation
ICD-10 J45.31 is a billable code used to indicate a diagnosis of mild persistent asthma with (acute) exacerbation.
J45.31 refers to mild persistent asthma with (acute) exacerbation, a condition characterized by intermittent symptoms that occur more than twice a week but less than daily, and nighttime symptoms occurring more than twice a month. The respiratory system, particularly the bronchi and bronchioles, is primarily affected, leading to inflammation, bronchoconstriction, and increased mucus production. Patients may experience wheezing, shortness of breath, chest tightness, and coughing, particularly during physical activity or exposure to allergens. Disease progression can vary; while some patients may maintain control with minimal intervention, others may experience frequent exacerbations requiring more intensive management. Diagnostic considerations include a thorough patient history, physical examination, and spirometry to assess lung function. Peak flow monitoring may also be utilized to evaluate the severity of asthma and the effectiveness of treatment. It is crucial to differentiate mild persistent asthma from other asthma classifications and respiratory conditions to ensure appropriate management and coding.

J45.31 specifically covers mild persistent asthma that is experiencing an acute exacerbation. This includes patients who have frequent symptoms that require additional treatment or intervention, distinguishing it from mild intermittent asthma (J45.30) and moderate or severe asthma classifications.
J45.31 should be used when a patient with mild persistent asthma presents with an acute exacerbation, characterized by increased symptoms and the need for additional medication or intervention. It is important to differentiate this from stable asthma or other asthma severity codes.
Documentation for J45.31 should include a detailed history of asthma symptoms, frequency of exacerbations, results from spirometry or peak flow measurements, and treatment plans. Records of medication use, patient education, and follow-up visits are also essential to support the diagnosis.
