.001number11This field, artificially created, provides easy direct access to the file. The first two digits are the ASCII value of the first character of the ICD-O code. The last three digits are the numeric portion of the ICD-O code, omitting the decimal point. Do not confuse this code with the 5-digit MORPHOLOGY code. One ICD-O TOPOGRAPHY code may have several corresponding MORPHOLOGY codes.
