Asthma diagnosis

Asthma diagnosis

This area has become more of a focus since COVID where usual spirometry activities have been paused.  In this article we summarise what you need to code following a diagnosis of asthma to achieve AST006 - Asthma with objective tests recorded.

Once a patient has been diagnosed with asthma, they need a code from Column "Code 1/SNOMED Code1" and a code from "Code 2/SNOMED Code 2" as well.  This will ensure they are coded correctly to achieve AST006
