Scenario:  2023 Diagnosis of Endometrial Cancer

  • Biopsy+ endometrial adenocarcinoma

Question: How would you code histology? [multiple choice below, choose one answer]

  • 8140 Adenocarcinoma
  • 8380 Endometrioid Adenocarcinoma, NOS

Answer: 8380 Endometrioid Adenocarcinoma

Rationale: Noticed that the term 8140 Adenocarcinoma is not in Table 16: Uterine Corpus Histologies, so submitted the question to AskSEERCTR.  They responded back. 

From: AskSEERCTR <askseerctr@imsweb.com> 

Yes, endometrial and endometrioid are synonyms. Endometrial adenocarcinoma is not recommended or preferred terminology. Endometrioid and endometrial adenocarcinoma are coded 8380/3.
