Exposure to X-rays

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 3 more specific codes instead:

  • W88.0XXA Exposure to X-rays, initial encounter
  • W88.0XXD Exposure to X-rays, subsequent encounter
  • W88.0XXS Exposure to X-rays, sequela

This code requires a seventh character. See the rule below.
