ICD-10-CM/PCS Neoplasms V: Diagnosis: Characteristics of Malignant Neoplasms Abstract This lesson provides information on the characteristics of malignant neoplasms. Related terminology and specific coding conventions and instruction needed for accurate coding are discussed including determining primary and secondary sites, determining the principal diagnosis, overlapping sites, coding notes, and guidelines. Before starting this lesson, be sure to complete the course ICD-10-CM Introduction to Inpatient Diagnosis Coding and the lesson "Diagnosis: An Overview" in the course ICD-10-CM/PCS Neoplasms . Before beginning this lesson, you should have access to the most recent version of ICD-10-CM (International Classification of Diseases, Tenth Revision, Clinical Modification). If you do not have the most recent copy of an ICD-10-CM code book, click the Resources tab for a link to the necessary documents. Be sure to download the index and tabular list, as well as the External Cause of Injuries Index, the Table of Drugs and Chemicals, and the Table of Neoplasms. The codes and information in this lesson are updated as needed and receive a comprehensive review annually. Learning Objectives By the time you have finished this lesson, you should be able to do (or know) the following: Distinguish between primary and secondary sites of neoplasm. Demonstrate knowledge of contiguous, noncontiguous, and vague sites of neoplasms by accurately coding these cases. Identify the appropriate neoplasm code to report when the primary site is unknown. Assign ICD-10-CM codes to common types of neoplasms.

Primary Site and Secondary Sites Malignant neoplasms are tumors that have the potential to spread ( metastasize ) by invading or attaching to adjacent structures or surrounding tissues. The tumor can extend to bordering tissue or to distant sites. Some, but not all, malignant neoplasms are noted for their rapid and relentless growth and have a high rate of mortality. Solid tumors are one type of malignant neoplasm. The primary site, where the tumor originates, must always be accounted for. These neoplasms are coded by anatomical site in categories C00- C76. Secondary sites are where the tumor has spread via extension or other means. They are coded in categories C77-C79. Malignant neoplasms found in lymphoid, hematopoietic, and related tissue are reported from code block C81-C96. Malignant primary and secondary neuroendocrine tumors are reported from code block C7A-C7B. In situ neoplasms are coded in code block D00-D09, In Situ Neoplasms. In situ neoplasms are malignant neoplasms that have not yet invaded the surrounding tissue or spread to other locations. Benign neoplasms and neoplasms of uncertain behavior are coded in the following code blocks: Benign Neoplasms, Except Benign Neuroendocrine Tumors (D10-D36); Benign Neuroendocrine Tumors (D3A); Neoplasms of Uncertain Behavior, Polycythemia Vera, and Myelodysplastic Syndromes (D37-D48).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
