Question:

Histology (Pre-2007)/Diagnostic Confirmation: What code is used to represent the histology that initially presents on uterine curettage as a hydatidiform mole and after pulmonary metastases develop a month later, the clinical diagnosis is "metastatic gestational trophoblastic disease"?

Discussion:

Answer:

For tumors diagnosed prior to 2007:

Code the Histology field to 9100/3 [Choriocarcinoma]. Gestational trophoblastic neoplasia includes the diagnosis of choriocarcinoma.

Code the Diagnostic Confirmation field to 8 [Clinical diagnosis only] based on the information above. However, if imaging, direct visualization, or another method identified the pulmonary metastases, then code the Diagnostic Confirmation accordingly.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
