T43.62 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, adverse effect of and underdosing of amphetamines. 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 Amphetamines

Non-specific codes like T43.62 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 amphetamines:

  • T43.621 for Poisoning by amphetamines, accidental (unintentional) - NON-BILLABLE CODE

  • Use T43.621A for initial encounter - BILLABLE CODE

  • Use T43.621D for subsequent encounter - BILLABLE CODE

  • Use T43.621S for sequela - BILLABLE CODE

  • T43.622 for Poisoning by amphetamines, intentional self-harm - NON-BILLABLE CODE

  • Use T43.622A for initial encounter - BILLABLE CODE

  • Use T43.622D for subsequent encounter - BILLABLE CODE

  • Use T43.622S for sequela - BILLABLE CODE

  • T43.623 for Poisoning by amphetamines, assault - NON-BILLABLE CODE

  • Use T43.623A for initial encounter - BILLABLE CODE

  • Use T43.623D for subsequent encounter - BILLABLE CODE

  • Use T43.623S for sequela - BILLABLE CODE

  • T43.624 for Poisoning by amphetamines, undetermined - NON-BILLABLE CODE

  • Use T43.624A for initial encounter - BILLABLE CODE

  • Use T43.624D for subsequent encounter - BILLABLE CODE

  • Use T43.624S for sequela - BILLABLE CODE

  • T43.625 for Adverse effect of amphetamines - NON-BILLABLE CODE

  • Use T43.625A for initial encounter - BILLABLE CODE

  • Use T43.625D for subsequent encounter - BILLABLE CODE

  • Use T43.625S for sequela - BILLABLE CODE

  • T43.626 for Underdosing of amphetamines - NON-BILLABLE CODE

  • Use T43.626A for initial encounter - BILLABLE CODE

  • Use T43.626D for subsequent encounter - BILLABLE CODE

  • Use T43.626S for sequela - BILLABLE CODE

Clinical Information

  • Amphetamines

    analogs or derivatives of amphetamine. many are sympathomimetics and central nervous system stimulators causing excitation, vasopressin, bronchodilation, and to varying degrees, anorexia, analepsis, nasal decongestion, and some smooth muscle relaxation.

  • Amphetamine

    a powerful central nervous system stimulant and sympathomimetic. amphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulation of release of monamines, and inhibiting monoamine oxidase. amphetamine is also a drug of abuse and a psychotomimetic. the l- and the d,l-forms are included here. the l-form has less central nervous system activity but stronger cardiovascular effects. the d-form is dextroamphetamine.

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 psychotropic drugs, not elsewhere classified (T43). Use the following options for the aplicable episode of care:

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

Patient Education


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.
