2018 EOD Manual. CNS Other schema
Question:
EOD 2018/Summary Stage 2018--Brain and CNS: What are the Extent of Disease (EOD) Primary Tumor, EOD Reg Nodes, and Summary Stage 2018 codes for intradural schwannoma of the lumbar spine (L2-L4)? See Discussion.
Discussion:
Example: Patient diagnosed following a resection of a cystic mass at L2-4 that proved an intradural tumor excision with final diagnosis of schwannoma, WHO grade 1.
Per new Solid Tumor Rules, the primary site in this case should be coded C476 (peripheral nerves of trunk, NOS) and histology is 9560/0 (schwannoma, NOS). However, there are currently no coding options in the Soft Tissue of Trunk and Extremities EOD schema relating to a benign tumor. Likewise there are no coding options in the Soft Tissue and Sarcoma Summary Stage 2018 schema relating to a benign tumor.
How should EOD 2018 and Summary Stage 2018 be coded for reportable benign schwannomas of the spinal nerve roots?
Answer:
The instruction regarding C476 has been removed from the Solid Tumor rules. Benign and borderline neoplasms coded to C470-C479 are not reportable at this time.
Assign C720 for an intradural schwannoma at L2-4. That should allow you to use the correct EOD and Summary Stage 2018 schemas.
