ICD 10 coding tips for Unspecified Bacterial diseases

Other specified and Unspecified are the ICD 10 codes should be always used carefully. When the specific ICD 10 code is available, we are not supposed to report any other specified or unspecified ICD 10 code. Coding for NEC (Not Elsewhere Classified) and NOS (Not otherwise Specified) have specific guidelines in diagnosis coding. Today, we will learn about the unspecified bacterial disease ICD 10 codes which have to be reported for few specific diseases. So, let us checkout the list of these ICD 10 codes.
