Frequently Asked Questions
What ICD-11 codes are in Chapter 2?
Chapter 2: Neoplasms covers ICD-11 codes 2A00-2F9Z. It contains 40 code blocks with 320 top-level categories.
What conditions does ICD-11 Chapter 2 cover?
Includes all codes for malignant neoplasms (cancers), benign tumors, carcinoma in situ, and neoplasms of uncertain or unknown behavior. ICD-11 improves tumor classification with morphology-based coding and updated staging conventions. This chapter includes codes from 2A00-2F9Z.
How is ICD-11 Chapter 2 different from ICD-10?
ICD-11 reorganized many chapters compared to ICD-10. Chapter 2 (Neoplasms) may include conditions that were in different ICD-10 chapters, and some conditions previously here may have moved. ICD-11 also adds new chapters for sleep-wake disorders, sexual health, and traditional medicine that did not exist in ICD-10.
How many code blocks are in ICD-11 Chapter 2?
Chapter 2 has 40 code blocks: 2A00-2A0Z (Neoplasms of central nervous system or related structures), 2A20-2A2Z (Myeloproliferative neoplasms), 2A20-2B3Z (Neoplasms of haematopoietic or lymphoid tissues), 2A30-2A3Z (Myelodysplastic syndromes), and 36 more.
