- Code Navigator:
T40.495 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of adverse effect of other synthetic narcotics. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.
Specific Coding Applicable to Adverse effect of other synthetic narcotics
Non-specific codes like T40.495 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for adverse effect of other synthetic narcotics:

Clinical Information
Alphaprodine
an opioid analgesic chemically related to and with an action resembling that of meperidine, but more rapid in onset and of shorter duration. it has been used in obstetrics, as pre-operative medication, for minor surgical procedures, and for dental procedures. (from martindale, the extra pharmacopoeia, 30th ed, p1067)Buprenorphine
a derivative of the opioid alkaloid thebaine that is a more potent and longer lasting analgesic than morphine. it appears to act as a partial agonist at mu and kappa opioid receptors and as an antagonist at delta receptors. the lack of delta-agonist activity has been suggested to account for the observation that buprenorphine tolerance may not develop with chronic use.Buprenorphine, Naloxone Drug Combination
a pharmaceutical preparation that combines buprenorphine, an opioid analgesics with naloxone, a narcotic antagonists to reduce the potential for narcotic dependence in the treatment of pain. it may also be used for opioid substitution therapy.Butorphanol
a synthetic morphinan analgesic with narcotic antagonist action. it is used in the management of severe pain.Dextropropoxyphene
a narcotic analgesic structurally related to methadone. only the dextro-isomer has an analgesic effect; the levo-isomer appears to exert an antitussive effect.Levopropoxyphene
a propionate derivative that is used to suppress coughing.Levorphanol
a narcotic analgesic that may be habit-forming. it is nearly as effective orally as by injection.Meperidine
a narcotic analgesic that can be used for the relief of most types of moderate to severe pain, including postoperative pain and the pain of labor. prolonged use may lead to dependence of the morphine type; withdrawal symptoms appear more rapidly than with morphine and are of shorter duration.Nalbuphine
a narcotic used as a pain medication. it appears to be an agonist at kappa receptors and an antagonist or partial agonist at mu receptors.Pentazocine
the first mixed agonist-antagonist analgesic to be marketed. it is an agonist at the kappa and sigma opioid receptors and has a weak antagonist action at the mu receptor. (from ama drug evaluations annual, 1991, p97)Phenazocine
an opioid analgesic with actions and uses similar to morphine. (from martindale, the extra pharmacopoeia, 30th ed, p1095)
Coding Guidelines
When coding an adverse effect of a drug that has been correctly prescribed and properly administered, assign the appropriate code for the nature of the adverse effect followed by the appropriate code for the adverse effect of the drug.
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
Table of Drugs and Chemicals
The 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.
