EOD-Extension--Meninges: How do you code extension for a malignant meningioma that invades into the adjacent brain tissue?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 60. Code 60 is defined as a brain tumor that extends into the meninges. It is also the appropriate code to use for a tumor that extends from the meninges to the brain.
Surgery of Primary Site--Soft Tissue: What code is used to represent this field when an excisional biopsy of a soft tissue sarcoma is followed two weeks later with a wide excision (re-excision)?
For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 26 [partial resection]. According to the CoC, "Excision" in the surgery codes refers to the lesion and "partial resection" refers to the organ. The biopsy is a local excision (code 25). The wide resection is code 26, presuming that more than just the remaining lesion was removed.
Multiple Primaries (Pre-2007)--Vulva/Vagina: SEER Program Code Manual rule #3 on page 11 states "If a new cancer of the same histology is diagnosed in the same site after two months, consider this new cancer a separate primary unless stated to be recurrent or metastatic. Should vulva and vagina be exceptions to rule #3, as are prostate and bladder?
For tumors diagnosed prior to 2007:
No. There is no exception for vulva or vagina.
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: What code is used for histology "tubular carcinoma with lobular carcinoma in situ"?
For tumors diagnosed prior to 2007:
Assign code 8211/3 [Tubular carcinoma]. According to histology rule #2 for a single tumor on page 86 of the 2004 SEER manual, code the invasive histology when both invasive and in situ tumor are present.
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.
Surgery of Primary Site/Surgical Procedure of Other Site--Bladder: What codes are used to represent these fields for a deeply invasive bladder primary treated initially with a TURP (for suspected prostate extension that turns out to be pathologically negative) and a TURB that is subsequently treated with a cystoprostatectomy?
For cases diagnosed 1/1/2003 and after, code:
1. Surgery of Primary Site field to 60 [Radical cystectomy (male only)] because the cystoprostatectomy was the most extensive (definitive) surgery performed to the primary site.
2. Surgical Procedure of Other Site to 2 [Non-primary surgical procedure to other regional sites] based on the TURP.
Multiple Primaries (Pre-2007)--Kidney: How many primaries are reportable in a patient treated with a bilateral nephrectomy that revealed multiple tumors within each kidney and the histology in both the left and the right kidney was "renal cell carcinoma, indeterminate type: multiple histologically identical tumors" and the clinical discharge diagnosis was "bilateral renal cell carcinoma, probably surgically cured"? See discussion.
The SEER manual states "If only one histologic type is reported and if both sides of a paired site are involved within two months of diagnosis, a determination must be made as to whether the patient has one or two independent primaries." Frequently, the only statement we have is that "bilateral organs are involved." Additional guidelines for determining number of primaries would be helpful.
For tumors diagnosed prior to 2007:
Report this case as two primaries, left and right kidneys. According to our pathologist consultant, "The description sounds like bilateral multiple primaries. Multicentricity in the same kidney occurs in about 4% of all cases, and bilaterality in 0.5 to 3% (Atlas of Tumor Pathology, Tumors of the Kidney, Bladder, and Related Urinary Structures)."
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.
Date of Diagnosis: How do you code this field when the pathologic confirmation is delayed for 2 months because the clinician decides to "watch and see what happens" to a CT identified mass thought to be either a "metastasis from a previously diagnosed malignancy or a new primary"?
Code the Date of Diagnosis field to the date of the scan. This is the earliest date that a recognized medical practitioner said the patient had cancer. The diagnosis on the CT scan was a malignancy. The only question was whether the mass on the scan was metastatic or a primary.
First Course of Cancer-Directed Therapy--All Sites: How do we code retinoic acid?
The code for retinoic acid depends upon the primary site and histology of the tumor. Code retinoic acid (also called Vitamin A, tretinoin, ATRA, all-transretinoic acid or Vesanoid) in the Immunotherapy field as 01 [Immuno administered as first course therapy] for acute promyelocytic leukemia. This drug is given to patients as an alternative to chemotherapy.
For all other sites/histologies, code retinoic acid in the Other Cancer-Directed Therapy Field. Use code 2 [Other experimental cancer-directed therapy] or 3 [Double-blind clinical trial, code not yet broken] if the drug is given as part of a protocol. If the drug is not being given as part of a protocol or you don't know whether it is part of a protocol, use code 1 [Other cancer-directed therapy].
Histology (Pre-2007): What code is used to represent a review of slides histology of "in situ squamous cell carcinoma and multiple detached fragments of atypical papillary squamous epithelium; highly suspicious for invasive carcinoma"? See discussion.
The original pathologist indicated a final diagnosis of moderately differentiated squamous cell carcinoma. The slides were sent for review to another facility. The reviewing pathologist rendered the diagnosis stated in the question section.
For tumors diagnosed prior to 2007:
Code the Histology field to 8070 [squamous cell carcinoma].
The review diagnosis was also squamous cell carcinoma. The expression "atypical papillary squamous epithelium" does not modify the cancer histology.
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: What code is used to represent the histology "infiltrating lobular carcinoma, solid and classical subtypes"?
For tumors diagnosed prior to 2007:
Code the Histology field to 8520 [Lobular 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.
