Specific Coding for Toxic effect of other noxious substances eaten as foodOverview

Non-specific codes like T62 require more characters. Use one of these billable codes instead:

  • T62.0 for Toxic effect of ingested mushrooms

  • T62.0X for Toxic effect of ingested mushrooms

  • T62.1 for Toxic effect of ingested berries

  • T62.1X for Toxic effect of ingested berries

  • T62.2 for Toxic effect of other ingested (parts of) plant(s)

  • T62.2X for Toxic effect of other ingested (parts of) plant(s)

  • T62.8 for Toxic effect of other specified noxious substances eaten as food

  • T62.8X for Toxic effect of other specified noxious substances eaten as food

  • T62.9 for Toxic effect of unspecified noxious substance eaten as food

  • T62.91 for Toxic effect of unspecified noxious substance eaten as food, accidental (unintentional)

  • T62.92 for Toxic effect of unspecified noxious substance eaten as food, intentional self-harm

  • T62.93 for Toxic effect of unspecified noxious substance eaten as food, assault

  • T62.94 for Toxic effect of unspecified noxious substance eaten as food, undetermined

Coding GuidelinesGuidance

The appropriate 7th character is to be added to each code from block Toxic effect of other noxious substances eaten as food (T62). Use the following options for the applicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to T62: its own notes plus those printed at block T51-T65 and Chapter 19. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

On T62 itself
  • allergic reaction to food, such as:
  • 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)
  • food protein-induced enteropathy (K52.22)
  • gastroenteritis (noninfective) (K52.29)
  • toxic effect of aflatoxin and other mycotoxins (T64)
  • toxic effect of cyanides (T65.0-)
  • toxic effect of hydrogen cyanide (T57.3-)
  • toxic effect of mercury (T56.1-)
From Block T51-T65 Toxic effects of substances chiefly nonmedicinal as to source applies to 1,680 codes
  • contact with and (suspected) exposure to toxic substances (Z77.-)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes

Use Additional Code

Add a second code, after this one, to fully describe the condition.

From Block T51-T65 Toxic effects of substances chiefly nonmedicinal as to source applies to 1,680 codes
  • code(s):
  • for all associated manifestations of toxic effect, such as: respiratory conditions due to external agents (J60-J70)
  • personal history of foreign body fully removed (Z87.821)
  • to identify any retained foreign body, if applicable (Z18.-)
From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • code to identify any retained foreign body, if applicable (Z18.-)

Notes

General instructions on how these codes are used.

From Block T51-T65 Toxic effects of substances chiefly nonmedicinal as to source applies to 1,680 codes
  • When no intent is indicated code to accidental. Undetermined intent is only for use when there is specific documentation in the record that the intent of the toxic effect cannot be determined.
From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code
  • The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes.

7th Character

Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.

  • The appropriate 7th character is to be added to each code from category T62
Values for category T62 Encounter: Initial, Subsequent, Sequela
  • Ainitial encounter
  • Dsubsequent encounter

Excludes2 1

These codes carry an Excludes2 note naming T62: its condition is not part of those codes, and both may be reported when the patient has both.

Questions About T62Overview

What is the ICD-10 code for toxic effect of other noxious substances eaten as food?

T62 is the ICD-10-CM category for toxic effect of other noxious substances eaten as food, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is T62 (Toxic effect of other noxious substances eaten as food) a billable code?

No. This is a category header that groups the codes for toxic effect of other noxious substances eaten as food, and headers cannot be submitted on claims. Claims for toxic effect of other noxious substances eaten as food need a more specific code from this category, such as T62.0X1A, T62.0X1D, and T62.0X1S.

Can T62 be reported with a code from T78.0?

Not as a rule. The Excludes1 note on T62 lists "anaphylactic shock (reaction) due to adverse food reaction (T78.0-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
