Questions About C81Overview

Is C81 (Hodgkin lymphoma) a billable code?

No. This is a category header that groups the codes for hodgkin lymphoma, and headers cannot be submitted on claims. Claims for hodgkin lymphoma need a more specific code from this category, such as C81.00, C81.01, and C81.02.
