Allergic contact dermatitis due to metals

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

What This Code Means

An allergic skin reaction that occurs when the skin comes into direct contact with metal, such as nickel in jewelry, watches, or belt buckles.

Coding Tips

  • •Identify the specific metal causing the reaction when possible, as nickel is the most common culprit and may be documented separately
  • •Ensure the condition is confirmed as allergic (not irritant) contact dermatitis, which requires a documented allergic sensitization history
