Question:
Date of Diagnosis/EOD-Extension--Placenta: How do you code these fields for a patient who presents with a vaginal metastatic lesion for a placenta primary? Should EOD-Extension be coded to 60 [Other genital structures NOS: vagina, ovary, broad ligament, fallopian tube] or 85 [metastasis other than lung]? See discussion.
Discussion:
Pt had D&C Feb 5 with features of complete mole. On March 7, pt seen for a mass just inferior to the urethral meatus. At path, vaginal introitus fragments were consistent with choriocarcinoma. At time of March 23 admit for chemo, history is given as large hydatidiform mole evacuated Feb 5. Her beta hCG titers initially fell but approximately one month later hCG titers rose. At that time, she had an obvious vaginal metastatic lesion.
Answer:
For cases diagnosed 1998 or after: Code the Date of Diagnosis field to March 7, which is the date that the choriocarcinoma was first diagnosed. There was no slide review or clinical statement that the first occurrence was obviously malignant. Therefore, the vaginal mets is not progression and is codeable as extension. Code the EOD-Extension field to 60 [other genital structures, NOS] according to the current EOD scheme for placenta. Even though the mass is discontinuous, it is still included in code 60 per the guidelines of the FIGO system on which the EOD is based.
History:
For cases diagnosed prior to 1998: In the SEER EOD 2nd Ed, use the scheme for Corpus and Placenta. Code EOD-Extension to 60.
