The code comes under the category ‘R06 – Abnormalities of breathing.’ This code is used when a patient reports difficulty in breathing, although the cause has not yet been identified.
The ICD 10 code for SOB, R06.02, is commonly used in outpatient, emergency, and general medicine cases.
Is R06.02 ICD-10 billable?
The R06.02 ICD 10 code for shortness of breath is billable. This implies that it can be used for the purpose of insurance claims.

The coder must keep in mind that insurance claims often require definitive diagnoses rather than symptom-based coding. In cases where a diagnosis has been made, for instance, in cases of pneumonia, asthma, or heart failure, the code for shortness of breath should not be used.
Understanding the Dyspnea ICD-10 Code
The term “dyspnea” ICD-10 code has several coding options, depending on how it is documented. The most common is R06.02, but there are other coding options as follows:
R06.00 – Dyspnea, unspecified
R06.02 – Shortness of breath
R06.09 – Other forms of dyspnea
All these codes are included in the ICD 10 coding for respiratory symptoms. The right code should be used to avoid any denial of claims.
R06.02 vs R06.09—What's the Difference?
The main difference between R06.02 and R06.09 is often a point of confusion for coders. The difference is as follows:
R06.02 is often used when the provider has documented “shortness of breath.” The term is quite straightforward, and it is often used in general practice.
R06.09, on the other hand, is used when there is specific information about dyspnea, but it is of an unspecified type. If there is an instance where the provider has documented dyspnea on exertion, then R06.09 should be used instead of R06.02.
The difference is quite critical to understand to avoid any denial of claims.
