Radiation/Chemotherapy: How do we code radiation and chemotherapy when the only statement we have is that the patient is "referred to either an oncologist or a radiation therapist"?
For cases diagnosed 1/1/2003 and after: A referral does not mean that the radiation therapy or chemotherapy was actually recommended. These cases need follow-back to see if treatment was recommended and/or administered. Some registries code these cases as 8 [Radiation recommended, unknown if administered] or 88 [Chemotherapy recommended, unknown if it was administered] and routinely review all cases with 8 or 88 codes. Upon review, the codes are updated depending on the information found. If there is no information available, the code 8 or 88 is changed to 0 or 00 [None].
First Course Treatment/Surgical Margins of the Primary Site--Melanoma: Is margin status positive or negative when the lesion “approximates” margins? This was noted in the pathology report comment on a malignant melanoma in-situ shave biopsy. Follow-up with physicians is not possible in this situation.
Assign margin status as “positive” when stated as approximates margins as recommended by our expert pathologists. Approximating means coming right up to inked margin without the margin transecting the tumor.
Solid Tumor Rules (2018)/Histology--Lung: If the pathology states non-small cell carcinoma of the lung (NSCLC), consistent with squamous cell carcinoma, is the code non-small cell carcinoma according to the Solid Tumor Rules? The Medical Oncologist states that the tumor is a squamous cell carcinoma. In these instances would you code the squamous cell carcinoma since you have a definite physician statement?
Code the histology to SCC 8070/3.
Based on registrar feedback on the NSCLC rule, we added a rule that specifically addresses when ambiguous terminology can be used to code histology other than NSCLC. The lung rules were update 10/12/2018 so please make sure you are using the currently posted rules. The new rule is: Rule H3-Code the specific histology when the diagnosis is non-small cell lung carcinoma (NSCLC) consistent with (or any other ambiguous term) a specific carcinoma (such as adenocarcinoma, squamous cell carcinoma, etc.) when:
* Clinically confirmed by a physician (attending, pathologist, oncologist, pulmonologist, etc.)
* Patient is treated for the histology described by an ambiguous term
* The case is accessioned (added to your database) based on ambiguous terminology and no other histology information is available/documented
Example 1: The pathology diagnosis is NSCLC consistent with adenocarcinoma. The oncology consult says the patient has adenocarcinoma of the right lung. This is clinical confirmation of the diagnosis, code adenocarcinoma.
Histology (Pre-2007)--Kidney: Is 8316/3 [Cyst associated renal cell carcinoma] the appropriate code for 1) Cystic renal cell carcinoma, 2) Renal cell carcinoma mass with cystic areas and 3) Cystic renal cell carcinoma, clear cell type?
For tumors diagnosed prior to 2007:
Yes, ICD-O-3 histology code 8316 is the correct code for the three examples above.
There are two categories of cyst-associated renal cell carcinomas: Renal cell carcinoma originating in a cyst, and Cystic renal cell 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.
Flag: For cases diagnosed prior to 2001, how is the ICD-O-3 Conversion Flag set if the ICD-O-2 and ICD-O-3 histology and behavior fields are both directly coded, as registrars in this region are instructed to do when submitting late cases, and as a result no conversion is necessary? Is it to 0 [Morphology (Morph--Type&Behav ICD-O-3 originally coded in ICD-O-3)] or Blank [Not converted]?
Assign code 3 [converted with review].
In your scenario above, ICD-O-2 and ICD-O-3 are being independently coded which should yield the same result as converting the case and then reviewing it.
Otherwise, if there is an ICD-O-3 code which differs from the ICD-O-3 code based on the conversion criteria, it will trigger an edit.
This is a reportable primary. Langerhans cell histiocytosis (LCH) [9751/3] is a reportable neoplasm.
The term "self-healing" means that the neoplasm regressed without treatment. This is a known phenomenon.

MP/H Rules/Histology--Prostate: What is the histology code for a prostate case whose histology reads “adenoca with mixed ductal and acinar variants?
Assign 8523/3.
The 2013 revision to ICD-O-3 has a new code for mixed acinar ductal carcinoma; however, this new code will not be implemented in the U.S. until 2018 or later. Page 7 of the Guidelines for ICD-O-3 Update Implementation document released by NAACCR 1/1/2014 instructs us to use 8523/3 in the meantime.
MP/H Rules/Histology--Thyroid: Regarding rule H15, is the mixed code 8340 [Papillary carcinoma, follicular variant] used when there are subtypes of these histologies described, such as a tumor diagnosed with follicular and papillary microcarcinoma or should 8341 [Papillary microcarcinoma] be used?
For cases diagnosed 2007 or later:
For coding purposes, this is a papillary and follicular combination that would be coded to the combination code 8340/3 [Papillary carcinoma, follicular variant].
For thyroid cancer only, the term micropapillary does not refer to a specific histologic type. It means that the papillary portion of the tumor is minimal or occult, usually less than 1 cm. in diameter.
Grade, Differentiation--All Sites: If the grade given for the primary site is from a provisional diagnosis and the grade given for a metastatic site is from a final diagnosis, should we follow the SEER rule that says to code the grade as stated in the final diagnosis (e.g., Provisional diagnosis: High grade papillary serous carcinoma of ovary. Final dx: poorly differentiated adenocarcinoma in a caval lymph node)?
Code the Grade, Differentiation field to 4 [High grade] from the examination of the ovary (primary site). Do not code grade from a metastatic site.
