2027 ICD-10-CM Diagnosis Code T60.0X1AToxic effect of organophosphate and carbamate insecticides, accidental (unintentional), initial encounter
T60.0X1A is a billable ICD-10-CM diagnosis code for toxic effect of organophosphate and carbamate insecticides, accidental (unintentional), initial encounter. The 7th character A marks it as an initial encounter code, used while the patient is receiving active treatment. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 917 through 918. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under External cause codes: intent of injury, accidental/unintentional; External cause codes: poisoning by non-drug; and Toxic effects, initial encounter.

Coding GuidelinesGuidance
The appropriate 7th character is to be added to each code from block Toxic effect of pesticides (T60). 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 T60.0X1A: its own notes plus those printed at T60, block T51-T65, and Chapter 19. A note printed at a category, block or chapter applies to every code under it.
Includes
Further defines, or gives examples of, the content of the category.
- toxic effect of wood preservatives
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
- 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.
Use Additional Code
Add a second code, after this one, to fully describe the condition.
- code to identify any retained foreign body, if applicable (Z18.-)
Notes
General instructions on how these codes are used.
- 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.
- 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 T60
- Ainitial encounter this code
- Dsubsequent encounter
- Ssequela

Patient EducationClinical
Pesticides
Pests live where they are not wanted or cause harm to crops, people, or animals. Pesticides can help get rid of them. Pesticides are not just insect killers. They also include chemicals to control weeds, rodents, mildew, germs, and more. Many household products contain pesticides.

Code HistoryHistory
Questions About T60.0X1AOverview
Is T60.0X1A a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report toxic effect of organophosphate and carbamate insecticides, accidental (unintentional), initial encounter on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What does the 7th character A in T60.0X1A mean?
The final character A marks the initial encounter: use it while the patient is receiving active treatment for toxic effect of organophosphate and carbamate insecticides, accidental (unintentional), such as an emergency visit or first evaluation.
What MS-DRG does T60.0X1A group to?
When toxic effect of organophosphate and carbamate insecticides, accidental (unintentional), initial encounter is the principal diagnosis on an inpatient stay, it groups to MS-DRG 918, 917, with relative weights from 0.8716 to 1.5698 depending on complications. Higher weights mean higher Medicare reimbursement.
Can T60.0X1A be reported with a code from Z77?
Not as a rule. The Excludes1 note at block T51-T65, which applies to T60.0X1A, lists "contact with and (suspected) exposure to toxic substances (Z77.-)". 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).
What is the ICD-9 equivalent of T60.0X1A?
Under the General Equivalence Mappings, toxic effect of organophosphate and carbamate insecticides, accidental (unintentional), initial encounter converts to ICD-9-CM 989.3 (tox eff organphos/carbam) and E863.1 (acc pois-phosph pesticid). The mapping is approximate, so confirm the match fits the documentation.
