J45909 - Asthma without complications or specific type identified

International Classification of Diseases

Last updated: 10/3/2025

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code indicates you have asthma, but the specific type hasn't been determined and you're not currently experiencing severe complications. Asthma is a chronic condition where your airways become inflamed and narrow, making it harder to breathe. 'Uncomplicated' means you don't have additional serious issues like respiratory failure or severe attacks requiring emergency care. This is often used when asthma is newly diagnosed or when the exact subtype (like allergic or non-allergic asthma) hasn't been specified yet.

Additional Information

This is a common diagnosis for initial asthma cases. Treatment typically involves bronchodilators (rescue inhalers) and may include controller medications. Most patients with uncomplicated asthma can manage their condition well with proper treatment and lifestyle modifications.
