Inquiry Details
References:
2010 SEER Manual. Appendix C
Question:
Surgery of Primary Site--Brain and CNS: How should this field be coded when the procedure is stated to be a "stereotactic CORE biopsy" of a brain tumor? See Discussion.
Discussion:
The most recent version of the Brain Site Specific Surgery schema has a note that states "Assign code 20 [Local excision of tumor, lesion, or mass, excisional biopsy] for stereotactic biopsy of brain tumor." Does this also apply to a stereotactic CORE biopsy?
SINQ 20081118 also states that a stereotactic biopsy should be coded as Surgery of Primary Site code 20.
Answer:
Assign code 20 [Local excision of tumor, lesion, or mass, excisional biopsy] for a stereotactic core biopsy of brain tumor.
