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)

T39.8X6 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of underdosing of other nonopioid analgesics and antipyretics, not elsewhere classified. 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 Underdosing of nonopioid analges/antipyret, NEC

Non-specific codes like T39.8X6 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 underdosing of nonopioid analges/antipyret, nec:

  • Use T39.8X6A for initial encounter - BILLABLE CODE

  • Use T39.8X6D for subsequent encounter - BILLABLE CODE

  • Use T39.8X6S for sequela - BILLABLE CODE

Clinical Information

  • Smilax

    a plant genus of the family smilacaceae. members contain smiglasides (phenylpropanoid glycosides) and steroidal saponins. commercially it is sometimes adulterated with hemidesmus, which would affect experimental results. drinks called sarsaparilla and root beer have been prepared from the smilaz ornata (jamaican sarsaparilla) and sassafras.
  • Ketorolac

    a pyrrolizine carboxylic acid derivative structurally related to indomethacin. it is an nsaid and is used principally for its analgesic activity. (from martindale the extra pharmacopoeia, 31st ed)
  • Ketorolac Tromethamine

    a pyrrolizine carboxylic acid derivative structurally related to indomethacin. it is a non-steroidal anti-inflammatory agent used for analgesia for postoperative pain and inhibits cyclooxygenase activity.
  • Meptazinol

    a narcotic antagonist with analgesic properties. it is used for the control of moderate to severe pain.
  • Nefopam

    non-narcotic analgesic chemically similar to orphenadrine. its mechanism of action is unclear. it is used for the relief of acute and chronic pain. (from martindale, the extra pharmacopoeia, 30th ed, p26)
  • Phenazopyridine

    a local anesthetic that has been used in urinary tract disorders. its use is limited by problems with toxicity (primarily blood disorders) and potential carcinogenicity.
  • Sumatriptan

    a serotonin agonist that acts selectively at 5ht1 receptors. it is used in the treatment of migraine disorders.

Coding Guidelines

Underdosing refers to taking less of a medication than is prescribed by a provider or a manufacturer's instruction. Codes for underdosing should never be assigned as principal or first-listed codes. If a patient has a relapse or exacerbation of the medical condition for which the drug is prescribed because of the reduction in dose, then the medical condition itself should be coded.

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

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.

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?

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.
