Race--How and when is Appendix D, Race and Nationality Descriptions from the 2000 Census and Bureau of Vital Statistics, to be used? See Discussion.

For example, if race is recorded as unknown on the facesheet of a hardcopy medical record or in the race field of an electronic medical record, how should race be coded for the following descriptions found in the history and physical or consultation reports submitted by clinicians?

1) Patient is Czechoslovakian

2) Patient is born in Czechoslovakia

3) Patient is Ethiopian

4) Patient is born in Ethiopia

5) Patient is Japanese

6) Patient is born in Japan

7) Patient is Brazilian

8) Patient is born in Brazil

Would you code these cases any differently if these descriptions were actually used in the race fields in the medical record or on a death certificate?

Code the patient's stated race when possible. Refer to Appendix D, Race and Nationality Descriptions from the 2000 Census and Bureau of Vital Statistics, for guidance.

Use the lists in Appendix D when race is not stated but other information is provided in the medical record. The cases you provide are good examples of the use of Appendix D. They would be coded the same if the descriptions were used in the medical record or death certificate race fields.

20091059 CS Tumor Size--Breast: How is this field coded for DCIS that is present in scattered small foci over five of eight slides, and the greatest aggregate dimension measures 0.5 cm? See Discussion. Breast biopsy was prompted by abnormality seen on mammography. Would this be an example of when to code 996 (mammographic/xerographic diagnosis only, no size given; clinically not palpable) applies for the CS Tumor Size field?

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 005 [0.5 cm] in this case. According to the General Instructions for CS tumor size, it is acceptable to code an aggregate size stated by the pathologist (see instruction 4.i).

20091062 CS Site Specific Factor--Head & Neck: How is Site Specific Factor 2 coded when the pathologist describes regional lymph nodes as "matted"? See Discussion. The primary tumor is located in the tonsil. The patient underwent neck dissection. Pathology report stated there were matted regional lymph nodes. Does the term matted describe extracapsular extension? The definition for site specific factor 2 uses the term "fixed" to describe extracapsular extension (but not matted). For breast, fixed/matted appear to be interchangeable. Would they also be interchangeable for head and neck cases?

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."Matted" is not a synonym for "Fixed" in the CS schema for Head and Neck. "Matted" is not indicative of extracapsular extension for the Head and Neck schema.

20091061 Multiplicity Counter--Head & Neck: How is this field coded when a patient has carcinoma in the same location as a previous primary but it is unknown if there was a disease-free interval? See Discussion. Patient was diagnosed with squamous cell carcinoma, single tumor of the right true vocal cord in May 2008. Tumor was treated with radiation therapy and chemotherapy. Excision of right vocal cord mass in February 2009 shows squamous cell carcinoma. Assign code 01 [one tumor only] for the example provided (see discussion). Given the information provided, there is no reason to suspect that the February 2009 diagnosis represents new tumor; therefore, it does not affect the multiplicity counter. It appears that this was the treatment plan for the original diagnosis in May 2008: radiation and chemo followed by excision of the mass. 2009

MP/H Rules/Multiple primaries--Urinary: How should we handle urinary tract tumors diagnosed before the MP rules went into effect when determining the number of primaries to report primaries? How do you apply rules M5, M6 and M8 when an invasive bladder tumor and other urinary site tumors occur before and after the effective date of these rules? See Discussion.

Example: Patient with a prior in situ carcinoma of the bladder in 11/89, left ureter papillary transition cell carcinoma in situ diagnosed in 5/05, left renal pelvis papillary transition cell carcinoma in situ diagnosed in 8/07 and invasive bladder carcinoma diagnosed in 3/08. When an invasive bladder tumor and other urinary site tumors occur, do you stop with the bladder at rule M5 and M6 never reaching M8?

For cases diagnosed 2007 or later:

Use the 2007 MP/H rules for urinary sites to assess diagnoses made in 2007-2014. Use the multiple tumors module to compare a diagnosis in 2007-2014 to an earlier diagnosis.

For the example above, start by comparing the left renal pelvis diagnosis in 8/07 to the earlier left ureter primary diagnosed 5/05. Start with rule M3. Stop at rule M8. The 8/07 renal pelvis diagnosis is not a new primary. Next, compare the 3/08 bladder tumor to the earlier left ureter primary diagnosed 5/05. Start with rule M3. Stop at rule M5. The 3/08 bladder tumor is a new primary because it is an invasive diagnosis following an in situ diagnosis. Use only the more recent of the two earlier urinary diagnoses for comparison. Do not compare the 2007 and later diagnoses to the 11/89 in situ bladder primary in this case.

MP/H Rules/Histology--Melanoma: How is histology coded for a "melanoma in situ, lentiginous type," arising in the skin of the lower leg? See Discussion.

In researching this, acral lentiginous melanoma is observed on the palms, soles and under the nails. To code to 8744, do we specifically have to see the word "acral" lentiginous melanoma?

For cases diagnosed 2007 to 2020

Assign 8742/2 [lentigo maligna] to "melanoma in situ, lentiginous type."

Acral lentiginous melanoma is not the same as melanoma, lentiginous type. "Acral lentiginous melanoma," 8744, should be used only if the report states acral lentiginous melanoma or malignant melanoma, acral lentiginous type.

Acral lentiginous melanoma most often occurs on the soles of the feet or the palms of the hands.

20091085 MP/H Rules/Histology--Breast: How is histology coded for a breast primary with a final diagnosis of "infiltrating duct carcinoma with apocrine features"? See Discussion. I & R has conflicting answers: #25719 (dated 3/17/2008) says per rule H12 this is 8401/3 but #23347 (dated 8/12/07) says per rule H16, this is 8523/3.

For cases diagnosed 2007 or later, assign histology code 8401/3 [apocrine adenocarcinoma] according to rule H12. Apocrine is a type of duct carcinoma, see table 1. Code 8401 should be listed in Rule H12. Apocrine should be removed from table 3.

These corrections will appear in the revised version of the rules.

20091076 Surgery of Primary Site/Scope Regional LN Surgery--Breast: How should these fields be coded when a sentinel lymph node dissection removes one-to-three axillary lymph nodes and a total/simple mastectomy is done? Assign code 41 [Total (simple) mastectomy, NOS WITHOUT removal of uninvolved contralateral breast] for Surgery of Primary Site. Assign code 2 [Sentinel lymph node biopsy] for Scope of Regional Lymph Node surgery. Code 41 applies to a total/simple mastectomy with any number of sentinel lymph nodes removed -- as long as all of the nodes removed are designated as sentinel nodes. 2009
20091096 MP/H Rules/Multiple primaries--Breast: How many primaries should be reported when an in situ diagnosis is followed by an invasive diagnosis in the same breast 1.5 years later? See Discussion. Patient had a core biopsy 1/07 that showed DCIS and PE showed no adenopathy. Patient refused resection, and adjuvant treatment. In 6/08, the pt returned for a modified radical mastectomy which showed infiltrating duct carcinoma and positive lymph nodes. A comment in the Correction Record stated "Per MD, patient did not see any urgency and delayed surgery 1.5 years after diagnosis." The patient did not have any treatment in that time period and there is no statement that there was progression. For cases diagnosed 2007 or later, abstract the 6/08 invasive diagnosis as a separate primary according to rule M8. Rule M8 applies whether or not the later diagnosis in this case is progression of disease. 2009
20091064 Radiation Sequence with Surgery--Head & Neck: How is this field coded for a tonsil primary diagnosed on 4/16/07 by a regional lymph node FNA when the patient subsequently initiates radiation on 5/8/07 and has a tonsillectomy with neck dissection on 7/30/07? The best way to handle this situation is to assign code 2 [Radiation before surgery] in Radiation Sequence with Surgery. Code 2 provides the best description of the sequence of events in this case. Radiation was delivered prior to the resection of the primary site. 2009
