Definition | ICD-9 Dual Coding Expression Syntax", description: ICD-9 allows dual coding. Refer to Section ?? of the ICD-9 Instruction Manual (ref?). \nThis OID identifies the code system that describes how to encode Dual Coding in a CD compatible expression (for Datatypes R2 CD only). \nAn ICD-9 dual code expression SHALL consist of two ICD-9 codes separated by space. This code system SHALL NOT be used for single ICD-9 codes; the normal ICD-9 code system oid which is 2.16.840.1.113883.6.3 should be used in this case.
