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 T60.1X2SOverview
Is T60.1X2S a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report toxic effect of halogenated insecticides, intentional self-harm, sequela on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What does the 7th character S in T60.1X2S mean?
The final character S makes this a sequela code: it reports a lingering problem that remains after the toxic effect of halogenated insecticides, intentional self-harm itself has resolved, not the original event.
What MS-DRG does T60.1X2S group to?
When toxic effect of halogenated insecticides, intentional self-harm, 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 T60.1X2S 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 halogenated insecticides, intentional self-harm, sequela on inpatient claims.
What is the ICD-9 equivalent of T60.1X2S?
Under the General Equivalence Mappings, toxic effect of halogenated insecticides, intentional self-harm, sequela converts to ICD-9-CM 909.1 (late eff nonmed substanc) and E959 (late eff of self-injury). 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.
