Unspecified asthma
ICD-10 J45.90 is a used to indicate a diagnosis of unspecified asthma.
Unspecified asthma (ICD-10 code J45.90) refers to a condition characterized by chronic inflammation of the airways, leading to recurrent episodes of wheezing, breathlessness, chest tightness, and coughing. The respiratory system, particularly the bronchi and bronchioles, is primarily affected, resulting in airflow obstruction. Asthma can vary in severity and may be triggered by allergens, respiratory infections, exercise, or environmental factors. The disease progression can lead to increased airway hyperresponsiveness and chronic airway remodeling if not managed appropriately. Diagnostic considerations include a thorough patient history, physical examination, and pulmonary function tests, such as spirometry, to assess airflow limitation. J45.90 is used when the specific type of asthma is not documented, making it essential for healthcare providers to ensure accurate diagnosis and management to avoid complications and improve patient outcomes.

J45.90 covers unspecified asthma, which may include various asthma types not otherwise specified, such as allergic asthma, exercise-induced asthma, or occupational asthma when the specific type is not documented.
J45.90 should be used when the specific type of asthma is not clearly documented in the patient's medical record. If the provider specifies the type of asthma, a more specific code should be selected.
Documentation should include a detailed patient history, symptom descriptions, triggers, treatment plans, and any diagnostic tests performed, such as spirometry results, to support the use of J45.90.
