Chronic obstructive pulmonary disease (COPD) is one of the most common respiratory disorders. There are three types of COPD: chronic bronchitis, asthma, and emphysema. The symptoms of COPD include shortness of breath, wheezing, chest pain, fatigue, and others.
Obstructive chronic bronchitis is a type of COPD which is reported by code 491.2. Code 492 is used to indicate emphysema. The other type of COPD that is asthma is coded by code 493.
If a patient diagnosed with chronic obstructive asthma, then it is coded by code 493.2. When a patient is diagnosed with acute bronchitis, then the code will be 466. Obstructive chronic bronchitis with acute bronchitis is reported by code 491.22.
Code 491.21 is used in the case when a patient suffers from obstructive chronic bronchitis with (acute) exacerbation. When a patient is diagnosed with chronic tracheobronchitis with COPD, use code 491.8.
Obstructive chronic bronchitis is reported by code 491.2, emphysema by code 492, and asthma by code 493. In exceptional cases, such as when a patient has asthma with COPD then use code 493.2.
E codes are required to report some respiratory conditions. Chronic obstructive pulmonary disease, pulmonary embolism, pneumonia are some of the common types of respiratory disorder.
Respiratory conditions may use E codes to explain how, and sometimes where, an external condition was involved in causing a health problem. For example, respiratory diseases due to chemical fumes would need an E code to identify the chemical.
The external conditions decide which insurance carrier's policy pays the medical expenses. For example, ventilation pneumonitis would require an E code to report sick building syndrome for worker's compensation.
E codes are used to explain how, and sometimes where an external factor was involved in causing respiratory conditions.
Pneumonia is an infection that inflames the air sacs in the lungs. It is a type of respiratory disorder. The symptoms of pneumonia include chest pain during breathing, fatigue, fever, nausea, vomiting, shortness of breath and others.
When the underlying diseases cause pneumonia, the practitioners are required to code the underlying sequence first, pneumonia second.
Hence, the option (a) is not the correct answer.
If a patient suffers from pneumonia due to underlying diseases such as HIV or whooping cough then, both the pneumonia condition and the underlying diseases are required to be coded.
Hence, the option (b) is not the correct answer.
Pneumonia can be caused due to underlying diseases such as HIV or whooping cough. In, such conditions, both HIV disease and pneumonia are reported by code.
Hence, the option (c) is not the correct answer.
Pneumonia can be a manifestation of HIV infection or whooping cough. In such cases, the underlying diseases are required to be listed first,followed by appropriate pneumonia code.
When pneumonia is caused by an underlying disease such as HIV (human immunodeficiency virus) or whooping cough, code of underlying disease should be listed first and pneumonia second.
Hence, the correct answer is option (d).
