  • Biopsy+ endometrial adenocarcinoma

  • 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.

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