Specific Coding for RadiodermatitisOverview

Non-specific codes like L58 require more characters. Use one of these billable codes instead:

  • Use L58.0 for Acute radiodermatitis

  • Use L58.1 for Chronic radiodermatitis

  • Use L58.9 for Radiodermatitis, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to L58: its own notes plus those printed at Chapter 12. A note printed at a category, block or chapter applies to every code under it.

Excludes2

Questions About L58Overview

What is the ICD-10 code for radiodermatitis?

L58 is the ICD-10-CM category for radiodermatitis, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is L58 (Radiodermatitis) a billable code?

No. This is a category header that groups the codes for radiodermatitis, and headers cannot be submitted on claims. Claims for radiodermatitis need a more specific code from this category, such as L58.0, L58.1, and L58.9.

Does L58 need an additional code?

When the condition applies, yes. The Use Additional Code note reads: code to identify the source of the radiation (W88, W90). The additional code is reported after L58.
