Allergy to milk products, unspecified

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

What This Code Means

A person has an allergic reaction to milk or milk products, but the specific tolerance level to processed milk (like baked goods) is not specified.

Coding Tips

  • •Use more specific codes (Z91.0111 or Z91.0112) if tolerance to baked milk is documented
  • •Document whether allergy includes lactose intolerance or is true IgE-mediated allergy
