#1: 2016 SEER Manual, 91
#2: 2007 MP/H Rules. Lung
Question:
MP/H Rules/Histology--Lung: What is the histology code for lung cancer case identified pathologically from a metastatic site that differs from the histology stated by the physician? See Discussion.
Discussion:
Bronchial washings were negative. Four lymph nodes were biopsied and found to have metastatic poorly differentiated neuroendocrine carcinoma. The treating oncologist calls it small cell carcinoma, extensive stage, and treats patient with carboplatin and VP-16 (etoposide) The MP/H rule says to take path/cyto from a metastatic site if no pathology/cytology available from the primary site. Is the physician's statement and treatment taken into consideration here?
Answer:
Code the histology based on the pathology report from the lymph node biopsy for this case. Pathology has higher priority than a physician's statement for assigning histology code. Use text fields to document the physician's statement.
