Note 1 This SSDI is effective for diagnosis years 2021+
- For cases diagnosed 2018-2020, leave this SSDI blank
Note 2 Physician statement of EGFR can be used to code this data item when no other information is available.
Note 3 EGFR may be recorded for all histologies and stages; however, it is primarily performed for advanced non-small cell carcinomas. If information is not available, code 9.
Note 4 The most common EGFR mutations are
- Exon 18 Gly719
- Exon 19 deletion
- Exon 20 insertion
- Exon 20 Thr790Met
- Exon 21 Leu858Arg
Note 5 If EGFR is positive and there is no mention of the mutated codon, or the mutated codon is not specified, code 4.
Note 6 If neoadjuvant therapy is given, record the assay from tumor specimens prior to neoadjuvant therapy.
- If neoadjuvant therapy is given and there are no EGFR results from pre-treatment specimens, report the findings from post-treatment specimens
Note 7 Code 9 when
- Insufficient amount of tissue available to perform test
- No microscopic confirmation of tumor
- EGFR not ordered or not done, or unknown if ordered or done
