  <description
               value="ICD-10 allows dual coding. Refer to Section 3.1.3 of the ICD-10 Instruction Manual (2nd Edition, http://www.who.int/entity/classifications/icd/ICD-10\_2nd\_ed\_volume2.pdf).

This OID identifies the code system that describes how to encode Dual Coding in a CD compatible expression (for Datatypes R2 CD only).

An ICD-10 dual code expression SHALL consist of two ICD-10 codes separated by space. This code system SHALL NOT be used for single ICD-10 codes; the normal ICD-10 code system oid which is 2.16.840.1.113883.6.3 should be used in this case.

Dual code expressions SHALL only be used per the rules described in the ICD-10 instruction manual.

**An example CD:**&lt;br&gt;&lt;/br&gt; &lt;example code=&quot;J21.8 B95.6&quot; codeSystem=&quot;2.16.840.1.113883.6.260&quot;&gt;&lt;br&gt;&lt;/br&gt; &lt;originalText value=&quot;Staph aureus bronchiolitis&quot;/&gt;&lt;br&gt;&lt;/br&gt; &lt;/example&gt;&lt;br&gt;&lt;/br&gt;&lt;br&gt;&lt;/br&gt; Where:&lt;br&gt;&lt;/br&gt; J21.8 is: Acute bronchiolitis due to other specified organisms&lt;br&gt;&lt;/br&gt; B95.6 is: Staphylococcus aureus as the cause of diseases classified to other chapters"/>
