California Cancer Reporting System Standards Volume I: Abstracting and Coding Procedures for Hospitals
Enter the patient's preexisting medical conditions, factors influencing health status, and/or complications during the patient's hospital stay for the treatment of the cancer. These factors may affect treatment decisions and influence outcomes.
Although data collection for these fields is required by the CCR if available, Comorbidity/Complications 1-10 will be collected from CoC facilities. Comorbidity/Complications fields 7-10 were added in 2006. Do not combine use of ICD-9-CM and ICD-10-CM codes in a single record. Refer to the FORDS Manual for 2013 for instructions.
If a comorbid condition is stated in the medical record but is not coded, do not attempt to code the condition in ICD-9-CM or ICD-10-CM.
EXAMPLE: If diabetes is mentioned in the medical record and it is not coded in the medical record do not attempt to code the condition in ICD-10-CM or fill in these fields.
ICD-9-CM or ICD-10-CM codes are valid for these data items. All are considered secondary diagnoses.

Note: For comorbid conditions (ICD-9-CM codes 00100-13980 and 24000-99990), there is an assumed decimal point between the third and fourth characters. For complications (ICD-9-CM codes E8700-E8799 and E9300-E9499), there is an assumed decimal point between the fourth and fifth characters. For conditions influencing health status and contact with health services (ICD-9-CM codes V0720-V0739, V1000-V1590, V2220- V2310, V2540, V4400-V4589, and V5041-V5049), there is an assumed decimal point between the third and fourth characters. For ICD-10-CM codes there is an assumed decimal between the third and fourth characters.
Some ICD-10-CM codes have more than five characters. Truncate the code by dropping the last digits on the right if this is encountered.
ONLY ICD-9-CM codes are allowed in this field. ICD-10-CM codes are to be coded in the data item Secondary Diagnosis; see section III.3.16.
