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)

T44.7X5A is a billable diagnosis code used to specify a medical diagnosis of adverse effect of beta-adrenoreceptor antagonists, 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.

This code describes a circumstance which influences the patient's health status but not a current illness or injury. The code is unacceptable as a principal diagnosis.

T44.7X5A is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like adverse effect of beta-adrenoreceptor antagonists. 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 Classification

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 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 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

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

  • Unacceptable principal diagnosis - There are selected codes that describe a circumstance which influences an individual's health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis.

Convert T44.7X5A to ICD-9-CM

  • ICD-9-CM Code: 995.29 - Adv eff med/biol NEC/NOS
    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: E941.3 - Adv eff sympatholytics
    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 T44.7X5 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.

Drug Reactions

Most of the time, medicines make our lives better. They reduce aches and pains, fight infections, and control problems such as high blood pressure or diabetes. But medicines can also cause unwanted reactions, such as drug interactions, side effects, and allergies.

What is a drug interaction?

A drug interaction is a change in the way a drug acts in the body when taken with certain other drugs, foods, or supplements or when taken while you have certain medical conditions. Examples include:

  • Two drugs, such as aspirin and blood thinners
  • Drugs and food, such as statins and grapefruit
  • Drugs and supplements, such as gingko and blood thinners
  • Drugs and medical conditions, such as aspirin and peptic ulcers

Interactions could cause a drug to be more or less effective, cause side effects, or change the way one or both drugs work.

What are side effects?

Side effects are unwanted, usually unpleasant, effects caused by medicines. Most are mild, such as a stomachache, dry mouth, or drowsiness, and go away after you stop taking the medicine. Others can be more serious. Sometimes a drug can interact with a disease that you have and cause a side effect. For example, if you have a heart condition, certain decongestants can cause you to have a rapid heartbeat.

What are drug allergies?

Drug allergies are another type of reaction. They can range from mild to life-threatening. Skin reactions, such as hives and rashes, are the most common type. Anaphylaxis, a serious allergic reaction, is less common.

How can I stay safe when taking medicines?

When you start a new prescription or over-the-counter medicine, make sure you understand how to take it correctly. Know which other medicines, foods, and supplements you need to avoid. Always talk to your health care provider or pharmacist if you have questions about your medicines.

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.
