2026 ICD-10-CM Diagnosis Code T60.3X1SToxic effect of herbicides and fungicides, accidental (unintentional), sequela
T60.3X1S is a billable ICD-10-CM diagnosis code for toxic effect of herbicides and fungicides, accidental (unintentional), sequela. The 7th character S marks it as a sequela code, which reports a problem that remains after the original condition has resolved. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 922 through 923. The code is exempt from POA reporting. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Poisoning/toxic effect/adverse effects/underdosing, sequela.

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 T60.3X1SOverview
Is T60.3X1S a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report toxic effect of herbicides and fungicides, accidental (unintentional), sequela on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What does the 7th character S in T60.3X1S mean?
The final character S makes this a sequela code: it reports a lingering problem that remains after the toxic effect of herbicides and fungicides, accidental (unintentional) itself has resolved, not the original event.
What MS-DRG does T60.3X1S group to?
When toxic effect of herbicides and fungicides, accidental (unintentional), sequela is the principal diagnosis on an inpatient stay, it groups to MS-DRG 922, 923, with relative weights from 1.0177 to 1.7494 depending on complications. Higher weights mean higher Medicare reimbursement.
Is T60.3X1S exempt from POA reporting?
Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for toxic effect of herbicides and fungicides, accidental (unintentional), sequela on inpatient claims.
What is the ICD-9 equivalent of T60.3X1S?
Under the General Equivalence Mappings, toxic effect of herbicides and fungicides, accidental (unintentional), sequela converts to ICD-9-CM 909.1 (late eff nonmed substanc) and E929.2 (late eff acc poisoning). 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.
