Question:
Seq no-central--Brain and CNS: How should subsequent tumors be sequenced when the patient has a history of a brain tumor, with no information on the behavior of the brain tumor? According to the sequencing rules, it appears some assumption must be made regarding the behavior of the brain tumor.
Discussion:
Answer:
Sequence the brain tumor in the 60-87 series when you do not know the behavior. If you have reason to believe the brain tumor was malignant, sequence it in the 00-59 series.
