CTR Prep (Mostra) Exam Complete Questions and Correct
Answers
Adenocarcinoma ICD Coding
Derived from glandular tissue; certain sites are commonly organs of metastasis, which are rarely
primary sites (brain, pleura, bone, soft tissue); if inconsistent, check further.
Compound Morphologies & Multiple Neoplasms ICD coding
Jan. 1, 2007 and after: Use Multiple Primary/Histology Rules.
Kaposi Sarcoma ICD coding
Multifocal, metastasizing, malignant reticulosis; may begin in oral cavity or visceral organs; if
uncertain of origin, or skin lesions found, code to skin C44.9.
Leukemia ICD coding
Code to bone marrow (C42.1) except for myeloid sarcoma or leukemia reticuloendotheliosis.
Melanoma ICD coding
Usually arise in skin but may be eye or visceral organs; brain is common site for mets but not primary
lesion. if unknown origin, code to skin NOS (C44.9)
Meningioma ICD coding
Code to 70.x (meninges), NOT brain
Mesothelioma ICD coding
Most often arises in pleura but may be in retroperitoneum; if unknown origin, code to pleura (C38.4)
Mycosis Fungoides, Sezary Disease ICD coding
T-cell malignancies which may be capable of transforming to lymphoma or leukemia; if non-specific
origin, code to skin NOS (C44.9)
Sarcoma ICD coding
Arise from mesoderm and derive specific name from the parent tissue; code NOS to soft tissue NOS
(C49.x)
Lymphoma ICD coding
SPECIAL Rules - usually generalized disease; code per primary Hematopoietic MPH rules, NOT just
were biopsy taken for site.
