Anaphyl rct d/t milk and dair prod w rct to bkd milk, subs

This code signifies a patient experiencing an anaphylactic reaction specifically triggered by milk and dairy products, with a confirmed reactivity even to milk that has been baked or extensively heated. This indicates a severe, systemic allergic response requiring immediate medical attention.

Apply this code for follow-up encounters related to the management, monitoring, or treatment of a patient who previously experienced anaphylaxis due to milk and dairy, including baked milk. This includes visits for allergy testing, desensitization therapy, or education on allergen avoidance after the initial acute event.

• Ensure documentation clearly specifies "anaphylactic reaction" and "subsequent encounter."
• Verify that the allergen is explicitly identified as milk/dairy, with a note of reactivity to baked milk.
• Do not use this code for initial encounters; an initial encounter code (e.g., T78.071A) would be appropriate for the first presentation of this anaphylaxis.
