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 topical agents primarily affecting skin and mucous membrane and by ophthalmological, otorhinorlaryngological and dental drugs
        (T49)

T49.4X4 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of poisoning by keratolytics, keratoplastics, and other hair treatment drugs and preparations, undetermined. 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 Poisoning by keratolyt/keratplst/hair trmt drug, undet

Non-specific codes like T49.4X4 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 poisoning by keratolyt/keratplst/hair trmt drug, undet:

  • Use T49.4X4A for initial encounter - BILLABLE CODE

  • Use T49.4X4D for subsequent encounter - BILLABLE CODE

  • Use T49.4X4S for sequela - BILLABLE CODE

Clinical Information

  • Allantoin

    a urea hydantoin that is found in urine and plants and is used in dermatological preparations.
  • Anthralin

    an anthracene derivative that disrupts mitochondria function and structure and is used for the treatment of dermatoses, especially psoriasis. it may cause folliculitis.
  • Capsaicin

    an alkylamide found in capsicum that acts at trpv cation channels.
  • Capsicum

    a plant genus of the family solanaceae. the hot peppers yield capsaicin, which activates vanilloid receptors. several varieties have sweet or pungent edible fruits that are used as vegetables when fresh and spices when the pods are dried.
  • Anacardic Acids

    a group of 6-alkyl salicylic acids that are found in anacardium and known for causing contact dermatitis.
  • Salicylates

    the salts or esters of salicylic acids, or salicylate esters of an organic acid. some of these have analgesic, antipyretic, and anti-inflammatory activities by inhibiting prostaglandin synthesis.
  • Salicylic Acid

    a compound obtained from the bark of the white willow and wintergreen leaves. it has bacteriostatic, fungicidal, and keratolytic actions.

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 topical agents primarily affecting skin and mucous membrane and by ophthalmological, otorhinorlaryngological and dental drugs (T49). 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.

Patient Education


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.
