2026 Benign Neoplasms ICD-10-CM Codes ICD-10-CM

The FY 2026 dataset contains 315 benign neoplasms codes across 32 code blocks. Benign neoplasm codes document tumors that are not malignant, the Benign column of the Table of Neoplasms. Benign neoplasms may grow but typically do not spread. Each code below lists the anatomical sites that map to it.

Questions About This Page

How do I find the right code for a specific site?

Type the anatomical site into the filter above. Every code on this page carries the site entries that map to it in the Table of Neoplasms. For all six behavior columns side by side, use the Table of Neoplasms.

How is neoplasm behavior determined?

The pathology or clinical documentation names the behavior. When the description of the neoplasm states the behavior, that description overrides the Index guidance, and the matching column of the Table of Neoplasms supplies the code.

How many benign neoplasms codes are there?

The FY 2026 dataset contains 315 benign neoplasms codes across 32 code blocks, 280 of them billable.
