Question
Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for plasma cell myeloma with radiologic evidence of multiple lytic lesions? See Discussion.

Discussion
Patient complained of pain in the right side and back right upper flank area. CT shows an anterior mediastinal mass and abnormal appearance of skeleton. CXR: Age indeterminate T8 compression fracture. CT chest: abnormal appearance of skeleton. Correlate clinically for myeloma or mets. Acute T5 or T8 compression fractures. Anterior mediastinal mass which may represent thymoma, lymph nodes or metastases. 03/22/12 Metastatic Series: Nonspecific hypodensities in pelvis, left hip and right acromion. Possibility of myeloma can't be totally excluded. Bone marrow right post iliac crest core biopsy, clot section and aspirate: plasma cell myeloma.

Should the primary site be coded to the bone marrow because the diagnosis of plasma cell myeloma was supported by radiologic evidence of multiple lytic lesions? The bone marrow biopsy confirmed the radiology reports.

Answer
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Code the primary site to C421 [bone marrow] per the Heme DB and Rule PH30. The Primary Site(s) section in the Heme DB indicates the primary site for plasma cell myeloma is C421 [bone marrow].

The Primary Site Coding Instructions in the Heme Manual (Rule 1) states that when a specific code is listed under the Primary Site(s) section of the Heme DB it is the only primary site code that can be assigned for that leukemia, myelodysplastic syndrome or myeloproliferative syndrome. Applying the PH Rules will result in the same answer for primary site, bone marrow [C421].
