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 drugs primarily affecting the autonomic nervous system
        (T44)

T44.7X4A is a billable diagnosis code used to specify a medical diagnosis of poisoning by beta-adrenoreceptor antagonists, undetermined, 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.

T44.7X4A 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 beta-adrenoreceptor antagonists undetermined. 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

  • Acebutolol

    a cardioselective beta-1 adrenergic antagonist with little effect on the bronchial receptors. the drug has stabilizing and quinidine-like effects on cardiac rhythm, as well as weak inherent sympathomimetic action.
  • Alprenolol

    one of the adrenergic beta-antagonists used as an antihypertensive, anti-anginal, and anti-arrhythmic agent.
  • Atenolol

    a cardioselective beta-1 adrenergic blocker possessing properties and potency similar to propranolol, but without a negative inotropic effect.
  • Betaxolol

    a cardioselective beta-1-adrenergic antagonist with no partial agonist activity.
  • Bisoprolol

    a cardioselective beta-1 adrenergic blocker. it is effective in the management of hypertension and angina pectoris.
  • Bupranolol

    an adrenergic-beta-2 antagonist that has been used for cardiac arrhythmia, angina pectoris, hypertension, glaucoma, and as an antithrombotic.
  • Carteolol

    a beta-adrenergic antagonist used as an anti-arrhythmia agent, an anti-angina agent, an antihypertensive agent, and an antiglaucoma agent.
  • Celiprolol

    a cardioselective beta-1 adrenergic antagonist that has intrinsic sympathomimetic activity. it is used in the management of angina pectoris and hypertension.
  • Metoprolol

    a selective adrenergic beta-1 blocking agent that is commonly used to treat angina pectoris; hypertension; and cardiac arrhythmias.
  • Nadolol

    a non-selective beta-adrenergic antagonist with a long half-life, used in cardiovascular disease to treat arrhythmias, angina pectoris, and hypertension. nadolol is also used for migraine disorders and for tremor.
  • Oxprenolol

    a beta-adrenergic antagonist used in the treatment of hypertension, angina pectoris, arrhythmias, and anxiety.
  • Penbutolol

    a nonselective beta-blocker used as an antihypertensive and an antianginal agent.
  • Pindolol

    a moderately lipophilic beta blocker (adrenergic beta-antagonists). it is non-cardioselective and has intrinsic sympathomimetic actions, but little membrane-stabilizing activity. (from martindale, the extra pharmocopoeia, 30th ed, p638)
  • Practolol

    a beta-1 adrenergic antagonist that has been used in the emergency treatment of cardiac arrythmias.
  • Propranolol

    a widely used non-cardioselective beta-adrenergic antagonist. propranolol has been used for myocardial infarction; arrhythmia; angina pectoris; hypertension; hyperthyroidism; migraine; pheochromocytoma; and anxiety but adverse effects instigate replacement by newer drugs.
  • Sotalol

    an adrenergic beta-antagonist that is used in the treatment of life-threatening arrhythmias.
  • Timolol

    a beta-adrenergic antagonist that is similar in action to propranolol; the levo-isomer is more active. timolol has been proposed as an anti-hypertensive, anti-arrhythmic, anti-angina, and anti-glaucoma agent. it is also used in the treatment of migraine disorders and tremor.

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 drugs primarily affecting the autonomic nervous system (T44). Use the following options for the aplicable episode of care:

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

Convert T44.7X4A to ICD-9-CM

  • ICD-9-CM Code: 971.3 - Poisoning-sympatholytics
    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: E980.4 - Undet pois-med agnt 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 T44.7X4 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


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.
