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.

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, 2025 through September 30, 2026.

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 917, 918, with relative weights from 0.8571 to 1.5684 depending on complications. Higher weights mean higher Medicare reimbursement.

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.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
