T41.3X1S is a billable ICD-10-CM diagnosis code for poisoning by local anesthetics, 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.

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 anesthetics and therapeutic gases (T41). Use the following options for the applicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Clinical InformationClinical

  • Acupuncture Analgesia

    analgesia produced by the insertion of acupuncture needles at certain acupuncture points on the body. this activates small myelinated nerve fibers in the muscle which transmit impulses to the spinal cord and then activate three centers - the spinal cord, midbrain and pituitary/hypothalamus - to produce analgesia.
  • Adjuvants, Anesthesia

    agents that are administered in association with anesthetics to increase effectiveness, improve delivery, or decrease required dosage.
  • Anesthesia

    a state characterized by loss of feeling or sensation. this depression of nerve function is usually the result of pharmacologic action and is induced to allow performance of surgery or other painful procedures.
  • Anesthesia and Analgesia

    medical methods of either relieving pain caused by a particular condition or removing the sensation of pain during a surgery or other medical procedure.
  • Anesthesia Department, Hospital

    hospital department responsible for the administration of functions and activities pertaining to the delivery of anesthetics.
  • Anesthesia Recovery Period

    the period of emergence from general anesthesia, where different elements of consciousness return at different rates.
  • Anesthesia, Cardiac Procedures

    a range of methods used to induce unconsciousness; analgesia; and muscle relaxation during cardiac procedures.
  • Anesthesia, Caudal

    epidural anesthesia administered via the sacral canal.
  • Anesthesia, Closed-Circuit

    inhalation anesthesia where the gases exhaled by the patient are rebreathed as some carbon dioxide is simultaneously removed and anesthetic gas and oxygen are added so that no anesthetic escapes into the room. closed-circuit anesthesia is used especially with explosive anesthetics to prevent fires where electrical sparking from instruments is possible.
  • Anesthesia, Conduction

    injection of an anesthetic to inhibit nerve transmission in a specific part of the body.
  • Anesthesia, Dental

    a range of methods used to reduce pain and anxiety during dental procedures.
  • Anesthesia, Endotracheal

    procedure in which an anesthetic such as a gas or mixture of gases is inhaled through a tube into the lungs.
  • Anesthesia, Epidural

    procedure in which an anesthetic is injected into the epidural space.
  • Anesthesia, General

    procedure in which patients are induced into an unconscious state through use of various medications so that they do not feel pain during surgery.
  • Anesthesia, Inhalation

    anesthesia caused by the breathing of anesthetic gases or vapors or by insufflating anesthetic gases or vapors into the respiratory tract.

Questions About T41.3X1SOverview

Is T41.3X1S (Poisoning by local anesthetics, accidental (unintentional)) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report poisoning by local anesthetics, accidental (unintentional), sequela on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What does the 7th character S in T41.3X1S mean?

The final character S makes this a sequela code: it reports a lingering problem that remains after the poisoning by local anesthetics, accidental (unintentional) itself has resolved, not the original event.

What MS-DRG does T41.3X1S group to?

When poisoning by local anesthetics, 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 T41.3X1S 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 poisoning by local anesthetics, accidental (unintentional), sequela on inpatient claims.

What is the ICD-9 equivalent of T41.3X1S?

Under the General Equivalence Mappings, poisoning by local anesthetics, accidental (unintentional), sequela converts to ICD-9-CM 909.0 (late eff drug poisoning) 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.
