T78.071Anaphylactic reaction due to milk and dairy products with reactivity to baked milk

T78.071 is the ICD-10-CM diagnosis code for anaphylactic reaction due to milk and dairy products with reactivity to baked milk. It belongs to category T78 (adverse effects, not elsewhere classified), block T66-T78 (other and unspecified effects of external causes) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within T78.07 (anaphylactic reaction due to milk and dairy products), T78.071 is specifically for anaphylactic reaction due to milk and dairy products with reactivity to baked milk. Related codes cover with tolerance to baked milk (T78.070) and unspecified (T78.079).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

Don't report T78.071 together with the conditions in its Excludes1 note: Anaphylactic reaction due to milk and dairy products with tolerance to baked milk (T78.070).

It was added in FY2026, effective October 1, 2025.
