T40.2X1A is a billable diagnosis code used to specify a medical diagnosis of poisoning by other opioids, accidental (unintentional), initial encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.
T40.2X1A is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like poisoning by other opioids accidental (unintentional). According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.

Clinical Information
Codeine
an opioid analgesic related to morphine but with less potent analgesic properties and mild sedative effects. it also acts centrally to suppress cough.Dextrorphan
dextro form of levorphanol. it acts as a noncompetitive nmda receptor antagonist, among other effects, and has been proposed as a neuroprotective agent. it is also a metabolite of dextromethorphan.Dihydromorphine
a semisynthetic analgesic used in the study of narcotic receptors.Ethylmorphine
a narcotic analgesic and antitussive. it is metabolized in the liver by ethylmorphine-n-demethylase and used as an indicator of liver function.Ethylmorphine-N-Demethylase
a drug-metabolizing enzyme of the hepatic microsomal oxidase system which catalyzes the oxidation of the n-methyl group of ethylmorphine with the formation of formaldehyde.Etorphine
a narcotic analgesic morphinan used as a sedative in veterinary practice.Hydrocodone
narcotic analgesic related to codeine, but more potent and more addicting by weight. it is used also as cough suppressant.Hydromorphone
an opioid analgesic made from morphine and used mainly as an analgesic. it has a shorter duration of action than morphine.Glucuronosyltransferase
a family of enzymes accepting a wide range of substrates, including phenols, alcohols, amines, and fatty acids. they function as drug-metabolizing enzymes that catalyze the conjugation of udpglucuronic acid to a variety of endogenous and exogenous compounds. ec 2.4.1.17.Morphine
the principal alkaloid in opium and the prototype opiate analgesic and narcotic. morphine has widespread effects in the central nervous system and on smooth muscle.Morphine Dependence
strong dependence, both physiological and emotional, upon morphine.Morphine Derivatives
analogs or derivatives of morphine.Receptors, Opioid, mu
a class of opioid receptors recognized by its pharmacological profile. mu opioid receptors bind, in decreasing order of affinity, endorphins, dynorphins, met-enkephalin, and leu-enkephalin. they have also been shown to be molecular receptors for morphine.Oxycodone
a semisynthetic derivative of codeine.Oxymorphone
an opioid analgesic with actions and uses similar to those of morphine, apart from an absence of cough suppressant activity. it is used in the treatment of moderate to severe pain, including pain in obstetrics. it may also be used as an adjunct to anesthesia. (from martindale, the extra pharmacopoeia, 30th ed, p1092)Promedol
a narcotic analgesic similar to meperidine; it exists in four stereoisomers, two of which, the beta (isopromedol) and the gamma (trimeperidine) are active.Thebaine
a drug that is derived from opium, which contains from 0.3-1.5% thebaine depending on its origin. it produces strychnine-like convulsions rather than narcosis. it may be habit-forming and is a controlled substance (opiate) listed in the u.s. code of federal regulations, title 21 part 1308.12 (1985). (from merck index, 11th ed)
Coding Guidelines
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 narcotics and psychodysleptics [hallucinogens] (T40). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela
Convert T40.2X1A to ICD-9-CM
- ICD-9-CM Code: 965.09 - Poisoning-opiates NEC
Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment. - ICD-9-CM Code: E850.2 - Acc poison-opiates NEC
Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment.
Table of Drugs and Chemicals
The parent code T40.2X1 of the current diagnosis code is referenced in the Table of Drugs and Chemicals, this table contains a classification of drugs, industrial solvents, corrosive gases, noxious plants, pesticides, and other toxic agents.
According to ICD-10-CM coding guidelines it is advised to do not code directly from the Table of Drugs and Chemicals, instead always refer back to the Tabular List when doing the initial coding. Each substance in the table is assigned a code according to the poisoning classification and external causes of adverse effects. It is important to use as many codes as necessary to specify all reported drugs, medicinal or chemical substances. If the same diagnosis code describes the causative agent for more than one adverse reaction, poisoning, toxic effect or underdosing, utilize the code only once.
Patient Education
Medication Errors
Medicines treat infectious diseases, prevent problems from chronic diseases, and ease pain. But medicines can also cause harmful reactions if not used correctly. Errors can happen in the hospital, at the health care provider's office, at the pharmacy, or at home. You can help prevent errors by:
- Knowing your medicines. When you get a prescription, ask the name of the medicine and check to make sure that the pharmacy gave you the right medicine. Make sure that you understand how often you should take the medicine and how long you should take it.
- Keeping a list of medicines.
- Write down all of the medicines that you are taking, including the names of your medicines, how much you take, and when you take them. Make sure to include any over-the-counter medicines, vitamins, supplements, and herbs that you take.
- List the medicines that you are allergic to or that have caused you problems in the past.
- Take this list with you every time you see a health care provider.
- Reading medicine labels and following the directions. Don't just rely on your memory - read the medication label every time. Be especially careful when giving medicines to children.
- Asking questions. If you don't know the answers to these questions, ask your health care provider or pharmacist:
- Why am I taking this medicine?
- What are the common side effects?
- What should I do if I have side effects?
- When should I stop this medicine?
- Can I take this medicine with the other medicines and supplements on my list?
- Do I need to avoid certain foods or alcohol while taking this medicine?

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.
