Allergic contact dermatitis due to other agents

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

An allergic skin reaction caused by contact with substances other than those specifically listed, such as metals, adhesives, or other materials that trigger an immune response in sensitive individuals.

Coding Tips

  • •Use this code when the specific allergic contact dermatitis agent is not captured by other L23 codes; document the causative agent in the medical record for clarity
  • •This is a more specific code than L23.9, so use L23.89 only when you can identify the agent but it doesn't fit other categories
