About ICD-10-CM T62
ICD-10-CM code T62 represents Toxic effect of other noxious substances eaten as food. This is a non-billable header code in the Injury, Poisoning, and External Causes chapter (block T62). The 2026 edition of ICD-10-CM T62 became effective on October 1, 2025. Non-billable codes cannot be used as a primary or secondary diagnosis on a claim, use a more specific child code instead.
Coding Tips for T62
Specialist guidance from the PayerReady Medical Coding Team. Specificity warnings, HCC capture rules, sequencing notes.
Injury codes require a 7th character: A (initial encounter, active treatment), D (subsequent, healing/recovery), S (sequela, late effect of original injury). Codes with fewer than 6 characters need the placeholder X to bring them to 6 characters before adding the 7th. Wrong or missing 7th character is the #1 cause of injury claim denials.
Type 1 Excludes
Pure excludes, these codes can never be coded together with T62. The conditions are mutually exclusive (e.g., congenital vs acquired forms).

- anaphylactic shock (reaction) due to adverse food reaction (T78.0-)
- bacterial food borne intoxications (A05.-)
- dermatitis (L23.6, L25.4, L27.2)
- food protein-induced enterocolitis syndrome (K52.21)
