Primary site--Testis: In the absence of a specific statement that the patient's testicle(s) are descended, should the primary site for a testicular tumor be coded as C621 (Descended Testis) when the mass is palpable on physical exam or demonstrated on scrotal ultrasound? See discussion.
Surgery of Primary Site--Skin: Should this field be coded to 45 [wide excision or reexcision of lesion or minor (local) amputation with margins more than 1 cm, NOS], 46 [with margins between 1 and 2 cm], or 47 [with margins greater than 2 cm] for a skin primary diagnosed in 2003 when margins are stated exactly as 2 cm?
Surgery of Primary Site--Head & Neck: Is a composite resection performed for an oral cavity primary coded to 40 [Radical excision of tumor, NOS], 41 [Radical excision of tumor only], 42 [Combination of 41 with resection in continuity with mandibles (marginal, segmental, hemi-, or total resection], 43 [Combination of 41 with resection in continuity with maxilla (partial, subtotal, or total resection)]? See discussion.
Surgery of Primary Site--Corpus uteri: How are the surgery fields to be coded when patient undergoes hysterectomy and omentectomy for endometrial primary? See Discussion.
Histology/Polyp--Colon: Which histology code is used when a colon biopsy states adenocarcinoma arising in a polyp, but the resection path states only adenocarcinoma, and does not mention arising in a polyp. See Discussion.
First course treatment/Date therapy initiated--Breast: How is the Date of Initiation of Hormone Therapy field coded when a patient undergoes "Tamoxifen blunting" to achieve better MRI imaging after a biopsy but prior to definitive surgery which is followed by adjuvant Tamoxifen therapy? See Discussion.
MP/H Rules/Histology: The 2010 SEER Manual has omitted some useful information in the Histologic Type ICD-O-3 section, specifically the statement of "Do not revise or update the histology code based on subsequent recurrence(s)". Will this statement be added to the revisions of the MPH rules? See Discussion.
