Which chapter of ICD-10-CM covers neoplasms?

The chapter that covers neoplasms in the ICD-10-CM coding system is Chapter 2. This chapter specifically categorizes both benign and malignant neoplasms, along with in situ neoplasms, and various other tumor-related conditions. The organization of Chapter 2 allows for a systematic arrangement of these conditions based on anatomical sites and specific behavior of the neoplasms, which is essential for accurate coding and billing in healthcare settings. This chapter is crucial for clinicians and coders because it provides detailed codes that specify the type and location of the neoplasm, aiding in both clinical treatment plans and statistical data collection. Understanding this classification helps ensure that diagnoses of tumors are accurately recorded and reflect the current medical understanding of neoplastic diseases.
