Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Poisoning by, adverse effect of and underdosing of drugs, medicaments and biological substances
      (T36-T50)
      • Poisoning by, adverse effect of and underdosing of nonopioid analgesics, antipyretics and antirheumatics
        (T39)

T39.393A is a billable diagnosis code used to specify a medical diagnosis of poisoning by other nonsteroidal anti-inflammatory drugs [nsaid], assault, 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.

T39.393A 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 nonsteroidal anti-inflammatory drugs [nsaid] assault. 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

  • Diclofenac

    a non-steroidal anti-inflammatory agent (nsaid) with antipyretic and analgesic actions. it is primarily available as the sodium salt.
  • Etodolac

    a non-steroidal anti-inflammatory agent and cyclooxygenase-2 (cox-2) inhibitor with potent analgesic and anti-arthritic properties. it has been shown to be effective in the treatment of osteoarthritis; rheumatoid arthritis; ankylosing spondylitis; and in the alleviation of postoperative pain (pain, postoperative).
  • Flufenamic Acid

    an anthranilic acid derivative with analgesic, anti-inflammatory, and antipyretic properties. it is used in musculoskeletal and joint disorders and administered by mouth and topically. (from martindale, the extra pharmacopoeia, 30th ed, p16)
  • Indomethacin

    a non-steroidal anti-inflammatory agent (nsaid) that inhibits cyclooxygenase, which is necessary for the formation of prostaglandins and other autacoids. it also inhibits the motility of polymorphonuclear leukocytes.
  • Meclofenamic Acid

    a non-steroidal anti-inflammatory agent with antipyretic and antigranulation activities. it also inhibits prostaglandin biosynthesis.
  • Mefenamic Acid

    a non-steroidal anti-inflammatory agent with analgesic, anti-inflammatory, and antipyretic properties. it is an inhibitor of cyclooxygenase.
  • Nabumetone

    a butanone non-steroidal anti-inflammatory drug and cyclooxygenase-2 (cox2) inhibitor that is used in the management of pain associated with osteoarthritis and rheumatoid arthritis.
  • Piroxicam

    a cyclooxygenase inhibiting, non-steroidal anti-inflammatory agent (nsaid) that is well established in treating rheumatoid arthritis and osteoarthritis and used for musculoskeletal disorders, dysmenorrhea, and postoperative pain. its long half-life enables it to be administered once daily.
  • Sulindac

    a sulfinylindene derivative prodrug whose sulfinyl moiety is converted in vivo to an active nsaid analgesic. specifically, the prodrug is converted by liver enzymes to a sulfide which is excreted in the bile and then reabsorbed from the intestine. this helps to maintain constant blood levels with reduced gastrointestinal side effects.
  • Tolmetin

    a non-steroidal anti-inflammatory agent (anti-inflammatory agents, non-steroidal) similar in mode of action to indomethacin.

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 nonopioid analgesics, antipyretics and antirheumatics (T39). Use the following options for the aplicable episode of care:

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

Convert T39.393A to ICD-9-CM

  • ICD-9-CM Code: 965.61 - Pois-propionic acid derv
    Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment.

    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 T39.393 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


Pain Relievers

Pain relievers are medicines that reduce or relieve headaches, sore muscles, arthritis, or other aches and pains. There are many different pain medicines, and each one has advantages and risks. Some types of pain respond better to certain medicines than others. Each person may also have a slightly different response to a pain reliever.

Over-the-counter (OTC) medicines are good for many types of pain. There are two main types of OTC pain medicines: acetaminophen (Tylenol) and nonsteroidal anti-inflammatory drugs (NSAIDs). Aspirin, naproxen (Aleve), and ibuprofen (Advil, Motrin) are examples of OTC NSAIDs.

If OTC medicines don't relieve your pain, your doctor may prescribe something stronger. Many NSAIDs are also available at higher prescription doses. The most powerful pain relievers are opioids. They are very effective, but they can sometimes have serious side effects. There is also a risk of addiction. Because of the risks, you must use them only under a doctor's supervision.

There are many things you can do to help ease pain. Pain relievers are just one part of a pain treatment plan.

Poisoning

A poison is any substance that is harmful to your body. You might swallow it, inhale it, inject it, or absorb it through your skin. Any substance can be poisonous if too much is taken. Poisons can include:

  • Prescription or over-the-counter medicines taken in doses that are too high
  • Overdoses of illegal drugs
  • Carbon monoxide from gas appliances
  • Household products, such as laundry powder or furniture polish
  • Pesticides
  • Indoor or outdoor plants
  • Metals such as lead and mercury

The effects of poisoning range from short-term illness to brain damage, coma, and death. To prevent poisoning it is important to use and store products exactly as their labels say. Keep dangerous products where children can't get to them. Treatment for poisoning depends on the type of poison. If you suspect someone has been poisoned, call your local poison control center at 1-800-222-1222 right away.

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.
