ICD 10 Study Guide: Chapter 2 Neoplasms

ICD-10-CM Chapter 2 covers codes C00 through D49 — all neoplasms (tumors), whether malignant, benign, in situ, of uncertain behavior, or of unspecified behavior. Neoplasm coding is a high-frequency CPC® exam topic due to its complex sequencing rules and the need to correctly identify primary vs. secondary (metastatic) sites.
