Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Breast: How are the number of primaries, histologies and CS extension fields coded for breast tissue that contains separate areas of invasive ductal carcinoma, intraductal carcinoma and Paget disease? See Discussion.
Excisional biopsy of a breast mass: 1.0 cm tumor that was infiltrating ductal carcinoma, high grade, with an associated intraductal component with comedonecrosis.
Pathology report for the mastectomy three weeks later: no residual tumor was found near the original biopsy site. In another portion of the same breast was found high-grade intraductal carcinoma involving the nipple ducts, with Paget Disease of the nipple. (No size was given for this.)
For tumors diagnosed prior to 2007:
This is a single primary. According to Exception 3 of Multiple Primary Rule 6 for multiple tumors, combinations of Paget disease and ductal carcinoma are a single primary. The histology code for this case is 8541 [Paget disease and infiltrating duct carcinoma]. Assign CS extension code 10 [confined to breast tissue] based on the information above.
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 Site Specific Factor 3--Prostate: When a prostatectomy specimen shows tumor focally penetrating through the capsule into periprostatic striated muscle tissue, is the involvement coded to 041 [periprostatic tissue] or 052 [skeletal muscle, NOS]?
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.
Assign code 052 [Levator muscle, Skeletal muscle, NOS, Ureter]. The description for this case states periprostatic "striated" muscle tissue. According to our pathologist consultant, "striated muscle in this context is skeletal muscle and the term is being used to differentiate the muscle from smooth (non-striated) muscle." Smooth muscle involvement would be most likely be coded 050 [Extension to bladder neck...] because smooth muscle in a prostatectomy or TURP specimen is usually from the urinary bladder neck.
Histology (Pre-2007): What is the difference between code 8244/3 composite carcinoid (combined carcinoid and adenocarcinoma) and 8245/3 adenocarcinoid tumor?
For tumors diagnosed prior to 2007:
Assign code 8244/3 [composite carcinoid] when there is a combination of adenocarcinoma and carcinoid tumor.
Assign code 8245/3 [adenocarcinoid] when the diagnosis is exactly "adenocarcinoid."
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.
Histology (Pre-2007)--Breast: Is a "noninvasive papillary carcinoma, solid type, of the breast" coded to 8503/2 [noninfiltrating intraductal papillary carcinoma] or 8230/2 [Intraductal carcinoma, solid type]?
For tumors diagnosed prior to 2007:
Code histology to 8503/2 [Noninfiltrating intraductal papillary adenocarcinoma]. "Solid" is one of four subtypes of intraductal papillary carcinoma. The other subtypes are cribriform, micropapillary and spindle cell. ICD-O-3 does not provide codes for each intraductal papillary subtype, so code to intraductal papillary carcinoma.
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.
Other Therapy: Can herbal therapy be coded when used as a single therapy or when used in combination with conventional therapy as a complimentary treatment? See Discussion.
Page 201 of the SPCM 2004, item #5, states "Assign code 6 for unconventional methods whether they are single therapy or given in combination with conventional therapy." This statement itself is ok but there is no guideline on the use of complementary therapy when it is given as the only treatment. The SPCM, 3rd editon, page 140 states: "Use code '6' for alternative and complementary therapies ONLY IF the patient receives no other type of treatment." There is no such statement in the SPCM 2004.
Assign code 6 for unconventional methods whether they are single therapy (alternative medicine is the only treatment) or given in combination with conventional therapy (complementary medicine plus conventional).
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.
Reportability/In Situ--Prostate: Was there a time period when PIN III was reportable to SEER?
Per the 2004 SEER Manual, page 2, Reportable Diagnoses, Exceptions, 1.b.iii "Prostatic intraepithelial neoplasia (PIN III) of the prostate (C619). (Collection stopped effective with cases diagnosed 1/1/2001 and later.)"
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.
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.
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.
