Subacute cough

This code signifies a cough that has persisted for a duration longer than an acute cough but has not yet reached the chronicity of a chronic cough. It typically describes a cough lasting between three and eight weeks, often following an upper respiratory infection.

Apply this code when documentation specifies a cough lasting for several weeks, generally between 3 and 8 weeks, without an identified underlying chronic condition. This is commonly seen in post-infectious coughs or those resolving from an acute illness.

• Differentiate from acute cough (less than 3 weeks) and chronic cough (greater than 8 weeks).
• Avoid using this code if a more specific diagnosis for the cough's etiology is documented (e.g., bronchitis, asthma).
• Ensure the duration of the cough is clearly documented to support the "subacute" classification.
