Spinal cord tumors (including lipomas) are reportable when they arise in the spinal dura or nerve root. The tumor must be of the spinal cord itself or within the spinal cord dura. Spinal cord tumors are reportable when they arise in the intradural space. A reportable intradural tumor can be either intramedullary or extramedullary. Extramedullary intradural spinal tumors are reportable. A spinal tumor originating in the extradural space is not reportable. If it is outside the dura, it is not reportable because it would be outside the CNS. They are not reportable when they arise in the peripheral nerves.

Assign code 3 (Progressive disease (PD)(per managing/treating physician statement) for Neoadjuvant Treatment--Clinical Response and code 7 (Neoadjuvant therapy completed and planned surgical resection not performed) for Neoadjuvant Treatment--Treatment Effect. These are the best choices under the circumstances. Use text fields to record the details.

Assign code 500 for EOD Primary Tumor for now.

We have confirmed with AJCC that "invasion of" but not "through" the visceral peritoneum maps to a T2 and not T3. Involvement of the visceral peritoneum for Summary Stage is Regional and does not make a distinction between "invasion of" or "invasion through." Any involvement of the visceral peritoneum is regional.

To correct this situation would require a new code, which would derive a T2/RE. That code will be added to the updates for 2023.

Code 500 will derive the appropriate Summary Stage of 2 (Regional). We are aware that this will derive the incorrect T; however, there is no work around at this time that will derive the correct T and Summary Stage, so we are defaulting to deriving the correct Summary Stage.

The clinical assessment code takes priority over the pathological assessment code in this case because the clinical assessment was worse than the pathologic assessment. Although there was a pathological assessment, the clinical assessment is greater. According to the general coding guidelines for neoadjuvant therapy, code the worst information, which in this case is the clinical assessment.

The 2018 EOD General Instructions for EOD Regional Nodes, instruction #4, addresses neoadjuvant therapy as follows. Neoadjuvant (preoperative) therapy: If the patient receives neoadjuvant (preoperative) systemic therapy (chemotherapy, immunotherapy) or radiation therapy, code the clinical information if that is the most extensive lymph node involvement documented.

A new note is being included for the 2022 updates. Exception: If patient has neoadjuvant therapy, and the clinical assessment is greater than the pathological assessment, the clinical assessment code takes priority.

Do not report cases based only on the TI-RADS category. The most recent information from ACR on TI-RADS indicates that neither TI-RADS 4 nor TI-RADS 5 is clearly defined as malignancy. TI-RADS 4 is "moderately suspicious" and TI-RADS 5 is "highly suspicious" but they do not specify what they are suspicious for. We need more information to determine reportability.

Assign primary site code C473 for this case based on the information provided (peripheral nerves and autonomic nervous system of thorax).

From our expert pathologist consultant: The origin of neuroblastomas is generally in the adrenal medulla or one of the sympathetic ganglia on either side of the vertebral column (although they have been reported in many other locations given the migration of the neural crest cells embryologically).

Code the primary site to vulva. Use text fields to record the details.

According to the WHO classification, several types of primary vulvar mammary-like carcinoma have been reported. It is rare and is thought to arise from specialized anogenital mammary-like glands within the vulva. It does not arise from ectopic breast tissue and is does not represent metastatic breast carcinoma.

Abstract separate primaries using Rule M15 of the Hematopoietic and Lymphoid Neoplasms (Heme) Manual. The Heme Database states: Excluded from this category are progression of myeloproliferative neoplasms (MPNs) and evolution of primary MDS or primary MDS/MPN to acute myeloid leukemia (AML); in each of these latter cases evolution to AML is part of the natural history of the primary disease and it may be impossible to distinguish natural progression from therapy-related changes. There is no indication of transformation.

Assign code 22 for LUL wedge resection followed by a lingular-sparing LUL lobectomy and mediastinal lymph node dissection.  Code the lymph node surgery in Scope of Regional Lymph Node Surgery. We obtained input from an expert who agrees with this code. He states a lingula-sparing lobectomy is best coded as a segmentectomy because it is the same as an apical trisegmentectomy.

Always code primary site to the site of origin. Look for information about where the neoplasm originated. Primary site should always be coded to reflect the site of origin according to the medical opinion on the case. Always code the primary site based on where the tumor arose / site of origin. Site of origin may be indicated by terms such as "tumor arose from," "tumor originated in," or similar statements.

Refer to ICD-O-3.2 and ICD-O-3 for topographty codes that are associated with specific histologies whenthe medical documentation does not specify the primary site.
