2026 ICD-10-CM Diagnosis Code T41.3X1APoisoning by local anesthetics, accidental (unintentional), initial encounter

AHRQ’s CCSR groups this code into broader clinical categories.

• 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.

• Anesthesia, Intravenous

  process of administering an anesthetic through injection directly into the bloodstream.

• Anesthesia, Local

  a blocking of nerve conduction to a specific area by an injection of an anesthetic agent.

• Anesthesia, Obstetrical

  a variety of anesthetic methods such as epidural anesthesia used to control the pain of childbirth.

• Anesthesia, Rectal

  procedure involving the instillation of an anesthetic into the rectum.

• Anesthesia, Spinal

  procedure in which an anesthetic is injected directly into the spinal cord.

• Anesthetists

  persons trained and certified to administer anesthetics.

• Balanced Anesthesia

  the use of several anesthetics together in small amounts, as opposed to a larger amount of one drug, to induce loss of sensation and loss of consciousness.

• Brachial Plexus Block

  a blocking of neural conduction in the network of nerve fibers innervating the upper extremity.

• Cervical Plexus Block

  a blocking of neural conduction in the network of nerve fibers innervating the neck and shoulder.

• Cryoanesthesia

  anesthesia achieved by lowering either body temperature (core cooling) or skin temperature (external cooling).

• Electronarcosis

  profound stupor produced by passing an electric current through the brain.

• Emergence Delirium

  a form of delirium which occurs after general anesthesia.

• Geriatric Anesthesia

  conducting anesthesia procedures in aged adults, typically those aged 65 years and older.

• Intraoperative Awareness

  occurence of a patient becoming conscious during a procedure performed under general anesthesia and subsequently having recall of these events. (from anesthesiology 2006, 104(4): 847-64.)

• Malignant Hyperthermia

  rapid and excessive rise of temperature accompanied by muscular rigidity following general anesthesia.

• Neuroanesthesia

  anesthesia method that deals with the complexities of the physiology and pharmacology of the nervous system when providing anesthesia for patients undergoing neurological procedures.

• Onco-anesthesia

  methods used by specialized onco-anesthesiologists in the perioperative care of patients undergoing cancer-related diagnostic and therapeutic procedures. the aim is to minimize preoperative complications, expedite recovery, and facilitate early return to intended oncological treatment.

• Pediatric Anesthesia

  conducting anesthesia procedures in infants, children, and adolescents.

• Treatment Refusal

  patient or client refusal of or resistance to medical, psychological, or psychiatric treatment. (apa, thesaurus of psychological index terms, 8th ed.)

• Benzocaine

  a surface anesthetic that acts by preventing transmission of impulses along nerve fibers and at nerve endings.

• Bupivacaine

  a widely used local anesthetic agent.

• Dibucaine

  a local anesthetic of the amide type now generally used for surface anesthesia. it is one of the most potent and toxic of the long-acting local anesthetics and its parenteral use is restricted to spinal anesthesia. (from martindale, the extra pharmacopoeia, 30th ed, p1006)

• Etidocaine

  a local anesthetic with rapid onset and long action, similar to bupivacaine.

• Lidocaine

  a local anesthetic and cardiac depressant used as an antiarrhythmia agent. its actions are more intense and its effects more prolonged than those of procaine but its duration of action is shorter than that of bupivacaine or prilocaine.

• Lidocaine, Prilocaine Drug Combination

  a topical local anesthetic preparation that is composed of a mixture of lidocaine and prilocaine. it is used to provide anesthesia during minor surgery and for the treatment of premature ejaculation.

• Mepivacaine

  a local anesthetic that is chemically related to bupivacaine but pharmacologically related to lidocaine. it is indicated for infiltration, nerve block, and epidural anesthesia. mepivacaine is effective topically only in large doses and therefore should not be used by this route. (from ama drug evaluations, 1994, p168)

• Prilocaine

  a local anesthetic that is similar pharmacologically to lidocaine. currently, it is used most often for infiltration anesthesia in dentistry.

• Carboxylesterase

  carboxylesterase is a serine-dependent esterase with wide substrate specificity. the enzyme is involved in the detoxification of xenobiotics and the activation of ester and of amide prodrugs.

• Penicillin G Procaine

  semisynthetic antibiotic prepared by combining penicillin g with procaine.

• Procainamide

  a class ia antiarrhythmic drug that is structurally-related to procaine.

• Procaine

  a local anesthetic of the ester type that has a slow onset and a short duration of action. it is mainly used for infiltration anesthesia, peripheral nerve block, and spinal block. (from martindale, the extra pharmacopoeia, 30th ed, p1016).

• Propoxycaine

  a local anesthetic of the ester type that has a rapid onset of action and a longer duration of action than procaine hydrochloride. (from martindale, the extra pharmacopoeia, 30th ed, p1017)

• Tetracaine

  a potent local anesthetic of the ester type used for surface and spinal anesthesia.

• Trimecaine

  acetanilide derivative used as a local anesthetic.

Anesthesia

Anesthesia is the use of medicines, called anesthetics, to prevent pain during surgery and other medical procedures. Medicine may be given by injection, inhalation, topical lotion, spray, eye drops, or a skin patch.
