Surgery of Primary Site: What is the most extensive, invasive or definitive surgical procedure when the second surgical procedure performed has a lower surgery code? See discussion.
5/xx/14 Segmental Mastectomy(24): Ductal carcinoma with <1mm marg 6/xx/14 Breast Re-excision (23): Residual ductal carcinoma 1.5mm, marg neg
The code in Surgical Procedure of Primary Site should correspond to the most invasive, extensive, or definitive surgery when the patient has multiple surgical procedures of the primary site even if there is no residual tumor found in the pathologic specimen from the more extensive surgery. The timing of the procedures does not affect the code choice.
Assign code 27 for the first example. Assign code 24 for the second example.
Primary Site--Sarcoma: What is the best primary site code for an undifferentiated sarcoma of the pulmonary artery? See discussion.
Consolidation of the case: The operating hospital stated: SOFT TISSUE: Resection: Procedure: Radical resection Other: Pneumonectomy Tumor Site: Right pulmonary artery - They used code C383 (mediastinum NOS). The consulting hospital stated: Lung, right, pneumonectomy: High grade sarcoma consistent with intimal sarcoma; tumor involves pulmonary artery. They used code C449 (other soft tissue NOS). Would C493 (soft tissue thorax) be correct?
Code the primary site to pulmonary artery, C493. According to the WHO classification of tumors, intimal sarcomas are malignant mesenchymal tumors arising in large blood vessels. They show mostly intraluminal growth with obstruction of the vessel. They may occur in the pulmonary vessels or, less often, in the aorta.
MP/H/Histology--Breast: What MP/H Rule, histology, and behavior code for a breast primary apply to the following?
2 foci DCIS, solid, high grade (Grade 3) w/microca++
Apply the Multiple Primaries/Histology, Breast Rule H3: DCIS and a more specific in situ are coded to the more specific histology term which in this case is solid. Code the histology to ductal carcinoma in situ, solid type (8230/2). Based on the information provided, there is no invasive component. The term "microca ++" means micro-calcifications are present, not micro carcinoma.
Primary Site--Stomach: How do I code the primary site when the operative report and pathology report state that the tumor site is incisura of the stomach?
Assign C163. Incisura, incisura angularis, gastric angular notch, angular incisure of stomach all refer to the sharp angular depression in the lesser curvature of the stomach at the junction of the body with the pyloric canal. See Gastric angular notch in #12 on page 76 in the SEER manual, http://seer.cancer.gov/manuals/2015/SPCSM_2015_maindoc.pdf. See also the SEER training website, #12 on the illustration corresponds to the angular notch, http://training.seer.cancer.gov/ugi/anatomy/stomach.html. We will correct the key for this illustration.
Reportability/Histology--Head and Neck: Is mammary analogue secretory carcinoma (MASC) of the left submandibular gland reportable and how is it coded? See Discussion.
The physician is calling it an indolent tumor, pT3/NX/M0 stage 3 with positive margins. Is the correct code C509, 8502/3?
Mammary analogue secretory carcinoma (MASC) is reportable. MASC is a recently described tumor that predominantly arises in the parotid gland. In this case, if the primary site is submandibular gland, assign C080. We contacted our expert pathologist and he stated that the best code to use for MASC is 8502/3. Override any edits triggered by the combination of C080 and 8502/3.
Grade/Sarcoma--Breast: Is the correct grade for high grade angiosarcoma of the breast a code 3 or 4? The breast usually uses a three grade system but sarcoma is not a typical histologic type of the breast.
Assign grade code 4 using the sarcoma table. Nottingham or Bloom-Richardson (BR) Score/Grade does not apply to angiosarcomas. This is a good question and points out needed clarification of the grade rules.
SEER Summary Stage 2000--Melanoma: Can Clark's level classification still used to Summary Stage melanoma? It was previously used by AJCC TNM, but was not included in the 7th edition. I see it is still listed in the CAP protocols for melanoma.
Clark's level can be used to assign in situ, localized or regional summary stage.
If there is a discrepancy between the Clark’s level and the pathologic description of extent, use the higher Summary Stage code.
MP/H Rules/Histology--Testis: How should histology be coded for a testicular primary with a combination of teratoma, yolk sac tumor and embryonal carcinoma? See discussion.
Patient had a radical orchiectomy with the final diagnosis of "Mixed germ cell tumor with the following features -- histologic type: Mixed germ cell tumor (teratoma 50%, yolk sac tumor 25%, and embryonal 25%)."
Assign 9085/3. Code this combination of teratoma, yolk sac tumor, and embryonal tumor in the testis to mixed germ cell tumor (9085/3) based on the WHO Classification of Tumors of the Male Genital Organs.
MP/H Rules/Histology--Breast: How should histology be coded for a breast primary with resection final diagnosis of "Ductal carcinoma with neuroendocrine features?" See Discussion.
Should the histology for "Ductal carcinoma with neuroendocrine features" be coded to 8500 (Ductal carcinoma, NOS) or 8574 (Adenocarcinoma with neuroendocrine differentiation)?
Code the histology to 8574/3 for Ductal carcinoma with neuroendocrine features.
Ductal carcinoma is also called "invasive breast carcinoma of no special type." WHO classifies Invasive breast carcinoma with neuroendocrine differentiation as 8574/3.
Radiation Therapy--Breast: Are iodine 125 (I-125) seed implants for breast cancer coded as brachytherapy or as a localization technique similar to wire localization? See Discussion.
We are seeing many I-125 seed implants for breast cancer. Many of my associates are coding them as brachytherapy. I think they are the newest of the localization technique like wire localization but with greater accuracy. Most are done the same day as the surgery so brachytherapy does not make sense. Which is correct?
I-125 seeds could be used for brachytherapy for breast cancer or as a localization technique for nonpalpable breast tumors. If the seeds were in place a short time and removed as part of a breast surgical procedure, they were likely used for tumor localization. Radioactive seed localization (RSL) is thought to be more precise than the wire implantation technique for localizing lesions.
