D31.40

What This Code Means

A benign (non-cancerous) tumor that develops in the ciliary body, which is the part of the eye that controls the lens shape and produces fluid inside the eye. This code is used when the specific location within the ciliary body is not documented.

Coding Tips

• •Verify documentation specifies the ciliary body location; if a more specific site is documented (such as right eye D31.41 or left eye D31.42), use the more specific code instead of the unspecified code
• •Ensure the neoplasm is confirmed as benign in the pathology report or clinical documentation before assigning this code; malignant ciliary body tumors require different coding
