ICD-10: Z91.014

The ICD-10-CM code Z91.014 specifically refers to an allergy to mammalian meats, which is a condition characterized by an adverse immune response to the consumption of meat derived from mammals. This allergy is often associated with a condition known as alpha-gal syndrome, which is triggered by a bite from certain ticks, particularly the Lone Star tick. Here’s a detailed overview of this condition, its clinical implications, and relevant coding information.

Clinical Description

Overview of Allergy to Mammalian Meats

Allergy to mammalian meats is a type of food allergy that can lead to various symptoms upon ingestion of meats such as beef, pork, lamb, and other mammalian sources. The immune system mistakenly identifies proteins in these meats as harmful, leading to an allergic reaction.

Symptoms

Symptoms of an allergy to mammalian meats can vary widely and may include:
- Gastrointestinal Symptoms: Nausea, vomiting, diarrhea, and abdominal pain.
- Skin Reactions: Hives, rashes, or eczema.
- Respiratory Issues: Nasal congestion, difficulty breathing, or wheezing.
