Question
Primary site--Heme & Lymphoid Neoplasms: What is the correct primary site code for this case of plasma cell myeloma? See discussion.

Discussion
Patient complained of pain in the right side and back right upper flank area. CT shows Anterior mediastinal mass and abnorm appearance of skeleton. Chest EPA/LAT: 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, LN, or Mets. 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.

My question is will I code this to the bone marrow because this is a clinically diagnosed multiple myeloma supported by radiologic evidence of multiple lytic lesions? The bone marrow right post iliac crest confirmed the radiology reports.

Answer
Code to primary site C421

Per the Hematopoietic database, multiple myeloma always has primary site of C421.
