2026 ICD-10-CM Diagnosis Code T39.8X2SPoisoning by other nonopioid analgesics and antipyretics, not elsewhere classified, intentional self-harm, sequela
T39.8X2S is a billable ICD-10-CM diagnosis code for poisoning by other nonopioid analgesics and antipyretics, not elsewhere classified, intentional self-harm, 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 Mental and substance use disorders; sequela; and Poisoning/toxic effect/adverse effects/underdosing, sequela.

Coding GuidelinesGuidance
When coding a poisoning or reaction to the improper use of a medication (e.g., overdose, wrong substance given or taken in error, wrong route of administration), first assign the appropriate code from categories T36-T50. The poisoning codes have an associated intent as their 5th or 6th character (accidental, intentional self-harm, assault and undetermined). If the intent of the poisoning is unknown or unspecified, code the intent as accidental intent. The undetermined intent is only for use if the documentation in the record specifies that the intent cannot be determined. Use additional code(s) for all manifestations of poisonings.
The appropriate 7th character is to be added to each code from block Poisoning by, adverse effect of and underdosing of nonopioid analgesics, antipyretics and antirheumatics (T39). Use the following options for the applicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela

Questions About T39.8X2SOverview
Is T39.8X2S a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report poisoning by other nonopioid analgesics and antipyretics, not elsewhere classified, intentional self-harm, sequela on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What does the 7th character S in T39.8X2S mean?
The final character S makes this a sequela code: it reports a lingering problem that remains after the poisoning by other nonopioid analgesics and antipyretics, not elsewhere classified, intentional self-harm itself has resolved, not the original event.
What MS-DRG does T39.8X2S group to?
When poisoning by other nonopioid analgesics and antipyretics, not elsewhere classified, 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 T39.8X2S 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 poisoning by other nonopioid analgesics and antipyretics, not elsewhere classified, intentional self-harm, sequela on inpatient claims.
What is the ICD-9 equivalent of T39.8X2S?
Under the General Equivalence Mappings, poisoning by other nonopioid analgesics and antipyretics, not elsewhere classified, intentional self-harm, sequela converts to ICD-9-CM 909.0 (late eff drug poisoning) 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.
