Code Lupron given for breast cancer in the "Other" treatment field using code 6 (other-unproven). Lupron is still not an approved hormone treatment for breast cancer and should not be coded in the hormone field.

Code Lupron as second course therapy and code active surveillance as first course therapy in this scenario. The 2023 SEER Manual states to code all treatment data items to 0 or 00 (Not done) when the physician opts for active surveillance, deferred therapy, expectant management, or watchful waiting.  Assign code 2 to Treatment Status. 

Active surveillance is not the same as "refusing treatment."  Active surveillance is a valid option offered to the patient.  The patient chose this option and later changed their mind.  This is not a refusal of recommended treatment.

Document all the details in the appropriate treatment text fields.

Code Hormone therapy as 01 [Hormone therapy administered as first course therapy] when thyroid replacement therapy is part of the first course of treatment for follicular or papillary thyroid cancer following thyroidectomy.

Thyroid hormone replacement therapy has a treatment effect on differentiated (follicular and papillary) carcinomas of the thyroid. This treatment effect is not seen for most medullary and undifferentiated thyroid cancers.

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.

Code Gender X as 9 when that is the only information available. Use text fields to document the details.

Also refer to coding instruction #7.

When gender is not known

Assign code 1 when the primary site is C600 'C639

Assign code 2 when the primary site is C510 'C589

Assign code 9 for primary sites not included above

Code EOD Primary Tumor using the post neoadjuvant information for this case. Since the only information you have is the post neoadjuvant, code that. EOD combines clinical and pathological information.

Code Diagnostic Confirmation as 7, Radiology and other imaging techniques without microscopic confirmation for this case. Results of a FoundationOne Liquid biopsy/assay are not specific enough to diagnose this lung malignancy.

Code Cixutumumab as Other Therapy.  Cixutumumab is still in clinical trials and not approved by FDA yet. Though it is classified as an immunotherapy agent, it is not approved.

Code AML with monocytic differentiation as acute myeloid leukemia, NOS (9861/3) per consultation with our expert hematopathologist.

Acute monoblastic and monocytic leukemia (9891/3) and acute myelomonocytic leukemia (9867/3) are distinct entities according to the WHO. "AML with monocytic differentiation" is a descriptive diagnosis, whereas, "Acute monoblastic and monocytic leukemia" are specific diagnoses. In the WHO Classification of Tumours, Central nervous system tumours (4th Ed) in 2016, WHO began integrating information on molecular alterations that provide significant prognostic implications and/or a therapeutic target into the histology code/term itself. As a result it is also important to look at the molecular testing because acute myeloid leukemias can have different molecular mutations that could result in coding to a different histology code. In this case, there was no other information regarding additional immunophenotyping, so that is why AML, NOS was assigned.  Acute myeloid leukemia with monocytic differentiation has been added to the Hematopoietic and Lymphoid Neoplasm Database as an alternate name for 9861/3.

Code 8255 (adenocarcinoma with mixed subtypes). The Multiple Primaries/Histology Rule H6 applies as there are two or more specific renal cell carcinoma types, clear cell and sarcomatoid (Spindle cell), as listed in Table 1 of the kidney Terms and definitions.
