Also use code 9 when it is not known whether the patient had any distant metastases.

1 = Yes
8 = Not applicable
9 = Unknown whether the brain is involved; Not documented in patient record
This item was first collected in 2010. Because of delays in some hospitals in implementing registry software updates, data may be incomplete for 2010 diagnoses.
