Hello
Below are the codes and reference for the above scenario.
J44.0
J20.9
J45.901
The below is Reference from Handbook.
• Coding of Diseases of the Respiratory, Digestive, and Genitourinary Systems
• 19 Diseases of the Respiratory System
• CHRONIC OBSTRUCTIVE PULMONARY DISEASE
Category J44 is further subdivided to specify whether there is an acute lower respiratory infection (J44.0) and whether there is an exacerbation of the condition (J44.1). If applicable, a code from category J45 is assigned to specify the type of asthma. In the case of code J44.0, Chronic obstructive pulmonary disease with acute lower respiratory infection, an additional code should be reported to identify the infection. The codes in category J44 distinguish between uncomplicated cases (J44.9) and those in acute exacerbation (J44.1). An acute exacerbation is a worsening or a decompensation of a chronic condition. An acute exacerbation is not equivalent to an infection superimposed on a chronic condition, though an exacerbation may be triggered by an infection. For example, COPD with acute bronchitis should be coded to J44.0, rather than J44.1.
