CS Lymph Nodes/Scope of Regional Lymph Node Surgery--Prostate: When prostate cancer is an incidental finding at cystoprostatectomy for bladder cancer, is the pelvic lymph node dissection coded for the prostate as well as the bladder?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Yes, the pelvic lymph node dissection is coded as regional lymph node surgery for both primaries and the nodes are counted in collaborative staging for both primaries. The examination of the pelvic lymph nodes is relevant to both the bladder and the prostatic primaries.
CS Tumor Size--Breast: Is the largest focus or the total area coded for tumor size in a patient presenting with "scattered foci of DCIS, largest focus measuring 0.6cm. DCIS spans a total area of 2.1cm."
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Code the size of the largest focus in CS tumor size. Code the tumor size for this case as 006 (6mm or 0.6cm).
First Course Treatment/Surgery of Primary Site--Lung: How is radiofrequency ablation for lung primaries coded?
Assign code 15 [Local tumor destruction, NOS] in the Surgery of Primary Site field. RFA is a technique where a probe placed in or near a tumor sends radio waves into the tumor, causing it to heat up and kill the cancer cells. RFA doesn't fit neatly into code 12 or 13, so we are left with the NOS code.
Surgery of Primary Site--Melanoma: If the surgical margins are greater than 1 cm for length and width but less than 1 cm for depth, do we code surgery in the 30-33 range?
Yes, assign a surgery code from the 30-33 range when any margin is less than 1 cm. Since tumor thickness is an important prognostic factor for cutaneous melanoma, the deep margin is of particular importance.
Grade, Differentiation/Priorities: Which has priority, the differentiation or the nuclear grade for a liver biopsy histology described as "well differentiated hepatocellular carcinoma, nuclear grade 3/4"?
For most sites, differentiation has priority over the nuclear grade when both are specified (excluding breast and kidney). Assign grade code 1 [well differentiated] to the example above.
Primary Site/CS Extension/CS Lymph Nodes--Lung: How are these fields coded for untreated lung primaries when only limited information is available from scans, bronchoscopies and biopsies? See Discussion.
3/13/04 CT scan Chest: extensive mediastinal, subcarinal, rt hilar lymphadenopathy; separate tumor mass in medial rt lung
3/16/04 Bronchoscopy: RLL/RML completely obstructed with extrinsic compression. Impression: CA of lung with hilar adenopathy.
Bronchial wash: PD non small cell CA
Bx RLL: up to 0.2 cm PD Adenocarcinoma c/w primary lung CA.
Treatment not recommended.
Expired 5/03/04.

The primary is in the right lung according to the available information.
Assign CS extension code 10 [Tumor confined to one lung]. The only information on extension is that there is a tumor in one lung.
Assign CS Lymph Nodes code 20 [Mediastinal and subcarinal lymph node involvement]. The CT scan confirms mediastinal and subcarinal lymphadenopathy.
Code tumor Size as 999 [Unknown]. "Completely obstructed" is not a size. Do not code the size of the biopsy specimen.
Multiple Primaries--Lymphoma: How many primaries should be reported when there is a marginal zone B-Cell lymphoma [9699/3] diagnosed in 2000, and the clinician states that the diffuse large B-Cell type lymphoma [9680/3] diagnosed in 2004 was a transformation of the prior primary? See Discussion.
The Single Versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table indicates they are most likely "D" different disease processes. As any low grade lymphoma can transform, we suspect this represents a transformation (the clinician is regarding this as transformed).
How many primary/ies should be coded?
And, how?
For cases diagnosed prior to 1/1/2010:
Report this case as one primary according to the physician's opinion. Code the histology as 9699/3 [marginal zone B-Cell lymphoma, NOS] and code the date of diagnosis as 2000.
Code the physicians opinion regardless of whether or not it agrees with the Single Versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table. Use the table when the physician does not state whether or not there is a new primary.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
Histology (Pre-2007)/Diagnostic Confirmation: Which histology code is preferred if the CBD brushing is positive for malignant cells, cytologically most consistent with ductal adenocarcinoma [8500/3], and the common hepatic artery lymph node biopsy has metastatic adenocarcinoma, consistent with cholangiocarcinoma [8160/3]?
For tumors diagnosed prior to 2007:
Assign histology code 8160 [Cholangiocarcinoma]. Code from the pathology specimen when available. In this case, the only pathology is from the lymph node specimen.
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.
CS Extension--Cervix: How are "positive pelvic washings" coded for a cervical primary?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
According to the CS Steering Committee, positive pelvic washings for primary cervical cancer are not part of the staging criteria in the collaborative staging system (nor in TNM and FIGO). Document positive pelvic washings in a text field. The CS steering committee will add a statement to CS extension to clarify this for cervix uteri.
