20190009 | First Course Treatment/Surgery of Primary Site--Breast: How is "Goldilocks," also referred to as oncoplastic reconstruction, in the surgery section for breast cancer patients coded? |
Code Goldilocks mastectomy in Surgery of Primary Site. Breast surgery code 30 seems to be the best available choice for "Goldilocks" mastectomy. It is essentially a skin-sparing mastectomy with breast reconstruction. The choice between code 30 and codes in the 40-49 range depends on the extent of the breast removal. Review the operative report carefully and assign the code the best reflects the extent of the breast removal. |

Abstract a single breast primary. Apply MP/H Rule M3 as this is a single tumor identified in the biopsy at 8 o'clock and at the same location in the mastectomy specimen. Code the behavior as invasive according to rule H9. The first course of therapy ends when the documented treatment plan is completed, no matter how long, unless there is progression, recurrence, or treatment failure. |

20190005 | Primary Site--Bladder: Does instruction #4 in the Urinary Sites Solid Tumor Rules Instructions for Coding Primary Site apply to a mix of in situ and invasive urothelial tumors? Instruction #4: Code Urinary System NOS C689 when there are multiple non-contiguous tumors in multiple organs within the urinary system. See Discussion. |
Example: Patient has multiple biopsies with final diagnosis of in situ papillary urothelial carcinoma in the prostatic urethra and invasive papillary urothelial carcinoma in the bladder. How should primary site be coded in this type of mixed in situ and invasive situation? |
Code Urinary System NOS C689 for this case since there are two separate urinary sites involved. Apply instruction #4 when there is a mix of in situ and invasive urothelial tumors. |

20190004 | Systemic/Surgery Sequence: Does the Systemic/Surgery Sequence field apply to only the first surgery performed (Date of First Surgical Procedure) or does it apply to the most definitive surgery (Date Most Definitive Surgery) as well? See Discussion. |
Example: Bladder primary with transurethral resection of the bladder tumor (TURBT) on 2/17/2017 (Date of First Surgical Proc) followed by a second TURBT on 3/24/2017 (Date Most Definitive Surgery) with mitomycin C instilled on the second, most definitive TURB procedure. There is an edit failure (IFX166) when Systemic/Surgery Sequence is coded 5 (intra-operative systemic) and Systemic Date does not match Date of First Surgical Procedure. How should we capture the intra-operative systemic treatment during the second, most definitive TURB? Is the correct Surgery/Systemic Sequence code 3 (systemic after surgery) for this case because (intra-operative) chemo was technically given after the first surgery? |
Assign code 3 to Systemic/Surgery Sequence and document the intraoperative treatment in the text field. Surgery is defined as a Surgical Procedure to the Primary Site (codes 10-90), Scope of RLN Surgery (codes 1-7), or Surgical Procedure of Other Site (codes 1-5) in the 2018 SEER Manual. In this case, the treatment was after the first surgical procedure. |

20190003 | Solid Tumor Rules (2018/2021)/Multiple Primaries--Brain and CNS: How many primaries should be accessioned and what multiple primaries/histology rules apply to a meningioma of the spinal meninges and a meningioma of the cerebral meninges? See Discussion. |
Example: Brain MRI shows a mass along underside of right tentorium extending to posterior incisura consistent with meningioma. Spinal MRI shows mass at C4-5 level consistent with meningioma. Resection of spinal meningioma shows final diagnosis of meningioma and College of American Pathologists (CAP) protocol summary indicates Histologic Type (WHO classification of tumors of the central nervous system): Meningioma, meningothelial. There is no resection of the cerebral meningioma planned. Is the CAP protocol used if it provides a further subtype for meningiomas? Per Solid Tumor Rules, the final diagnosis has priority over the CAP summary. The answer to this question does affect the number of primaries accessioned in this case. |
Accession as multiple primaries using Rule M7 of the Solid Tumor Rules for Non-Malignant Central Nervous System that says to assign multiple primaries for cerebral meninges C700 AND spinal meninges C701. The Non-malignant CNS H coding section, Priority Order for using Documentation to Identify Histology" lists final DX and synoptic report as requried by CAP as being equal in priority. Use whichever report provides more specific information. See the General Instructions, page 13. |

20190001 | EOD 2018/Summary Stage 2018--Brain and CNS: What are the Extent of Disease (EOD) Primary Tumor, EOD Reg Nodes, and Summary Stage 2018 codes for intradural schwannoma of the lumbar spine (L2-L4)? See Discussion. |
Example: Patient diagnosed following a resection of a cystic mass at L2-4 that proved an intradural tumor excision with final diagnosis of schwannoma, WHO grade 1. Per new Solid Tumor Rules, the primary site in this case should be coded C476 (peripheral nerves of trunk, NOS) and histology is 9560/0 (schwannoma, NOS). However, there are currently no coding options in the Soft Tissue of Trunk and Extremities EOD schema relating to a benign tumor. Likewise there are no coding options in the Soft Tissue and Sarcoma Summary Stage 2018 schema relating to a benign tumor. How should EOD 2018 and Summary Stage 2018 be coded for reportable benign schwannomas of the spinal nerve roots? |
The instruction regarding C476 has been removed from the Solid Tumor rules. Benign and borderline neoplasms coded to C470-C479 are not reportable at this time. Assign C720 for an intradural schwannoma at L2-4. That should allow you to use the correct EOD and Summary Stage 2018 schemas. |

20180113 | Solid Tumor Rules (2018)/Histology--Lung: What is the histology code of a 2018 lung cancer case with invasive non-mucinous adenocarcinoma? For non-mucinous carcinoma/adenocarcinoma, the Solid Tumor Rules have codes for microinvasive, minimally invasive, preinvasive, and in situ. Do we default to the microinvasive/minimally invasive code? |
Code histology to adenocarcinoma, NOS (8140/3). The World Health Organization and the College of American Pathologists no longer recognize non-mucinous carcinoma/adenocarcinoma, NOS. Pathologists are discouraged from using this term. Microinvasive/minimally invasive lung tumors have very specific criteria and these criteria do not apply to non-mucinous carcinoma, NOS. |

20180112 | Solid Tumor Rules (2018)/Histology--Lung: What is the histology code of a non-small cell lung cancer (NSCLC), NOS as this is not on the AJCC list of histologies? See Discussion. |
A question was posted to CAnswer forum 9/26/18 and answered stating that 8046 is not on the AJCC list of histologies for the lung chapter in the 8th edition. If the final diagnosis on the pathology report is just NSCLC, NOS with no subtype/variant, what histology/solid tumor rule would I use? In this situation, I am not able to query the pathologist. Would I code the histology to 8010 as per AJCC post? |
Code NSCLC to 8046/3. Do not change a histology code simply to assign TNM to the case. AJCC does not determine histology coding. While pathologists are no longer encouraged to use NSCLC, it does not mean the term and code are obsolete. NSCLC could be any number of histologies such as adenocarcinoma or squamous carcinoma. A diagnosis of NSCLC indicates that the initial exam of the tissue did not identify a more specific type of NSCLC. Additional immunohistochemical testing is needed to determine the histology. Update the case if better information becomes available from subsequent tests/review. When analyzing the data, researchers and physicians will be able to identify the cases where the pathologist was unable to or did not perform further testing to determine a specific histology which drives treatment and survival. |
