Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Toxic effects of substances chiefly nonmedicinal as to source
      (T51-T65)
      • Toxic effect of metals
        (T56)

T56.892A is a billable diagnosis code used to specify a medical diagnosis of toxic effect of other metals, intentional self-harm, 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.

T56.892A is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like toxic effect of other metals intentional self-harm. 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.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Intentional lithium and/or lithium compound overdose
  • Intentional lithium poisoning
  • Lithium and/or lithium compound overdose
  • Lithium poisoning

  • Lithium Carbonate

    a lithium salt, classified as a mood-stabilizing agent. lithium ion alters the metabolism of biogenic monoamines in the central nervous system, and affects multiple neurotransmission systems.
  • Lithium Chloride

    a salt of lithium that has been used experimentally as an immunomodulator.
  • Lithium Compounds

    inorganic compounds that contain lithium as an integral part of the molecule.
  • Niacin

    a water-soluble vitamin of the b complex occurring in various animal and plant tissues. it is required by the body for the formation of coenzymes nad and nadp. it has pellagra-curative, vasodilating, and antilipemic properties.
  • Tellurium

    an element that is a member of the chalcogen family. it has the atomic symbol te, atomic number 52, and atomic weight 127.60. it has been used as a coloring agent and in the manufacture of electrical equipment. exposure may cause nausea, vomiting, and cns depression.
  • Nitrogenase

    an enzyme system that catalyzes the fixing of nitrogen in soil bacteria and blue-green algae (cyanobacteria). ec 1.18.6.1.
  • Vanadium

    a metallic element with the atomic symbol v, atomic number 23, and atomic weight 50.94. it is used in the manufacture of vanadium steel. prolonged exposure can lead to chronic intoxication caused by absorption usually via the lungs.
  • Vanadium Compounds

    inorganic compounds that contain vanadium as an integral part of the molecule.

Coding Guidelines

The appropriate 7th character is to be added to each code from block Toxic effect of metals (T56). Use the following options for the aplicable episode of care:

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

Replaced Code

This code was replaced in the 2024 ICD-10-CM code set with the code(s) listed below. The National Center for Health Statistics (NCHS) has published an update to the ICD-10-CM diagnosis codes which became effective October 1, 2023. This code was replaced for the FY 2024 (October 1, 2023 - September 30, 2024).


  • T56.822A - Toxic effect of gadolinium, self-harm, initial encounter

Convert T56.892A to ICD-9-CM

  • ICD-9-CM Code: 985.8 - Toxic effect metals NEC
    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: E950.9 - Poison-solid/liquid 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 T56.892 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.

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.
