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)

T56.2X4 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of toxic effect of chromium and its compounds, 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 Toxic effect of chromium and its compounds, undetermined

Non-specific codes like T56.2X4 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 toxic effect of chromium and its compounds, undetermined:

  • Use T56.2X4A for initial encounter - BILLABLE CODE

  • Use T56.2X4D for subsequent encounter - BILLABLE CODE

  • Use T56.2X4S for sequela - BILLABLE CODE

Approximate Synonyms

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

  • Contact dermatitis due to chromium

Clinical Information

  • Adenosine Triphosphate

    an adenine nucleotide containing three phosphate groups esterified to the sugar moiety. in addition to its crucial roles in metabolism adenosine triphosphate is a neurotransmitter.
  • Chromium

    a trace element that plays a role in glucose metabolism. it has the atomic symbol cr, atomic number 24, and atomic weight 52. according to the fourth annual report on carcinogens (ntp85-002,1985), chromium and some of its compounds have been listed as known carcinogens.
  • Chromium Alloys

    specific alloys not less than 85% chromium and nickel or cobalt, with traces of either nickel or cobalt, molybdenum, and other substances. they are used in partial dentures, orthopedic implants, etc.
  • Chromium Compounds

    inorganic compounds that contain chromium as an integral part of the molecule.
  • Chromium Isotopes

    stable chromium atoms that have the same atomic number as the element chromium, but differ in atomic weight. cr-50, 53, and 54 are stable chromium isotopes.
  • Chromium Radioisotopes

    unstable isotopes of chromium that decay or disintegrate emitting radiation. cr atoms with atomic weights of 46-49, 51, 55, and 56 are radioactive chromium isotopes.
  • Edetic Acid

    a chelating agent that sequesters a variety of polyvalent cations such as calcium. it is used in pharmaceutical manufacturing and as a food additive.
  • Oxalic Acid

    a strong dicarboxylic acid occurring in many plants and vegetables. it is produced in the body by metabolism of glyoxylic acid or ascorbic acid. it is not metabolized but excreted in the urine. it is used as an analytical reagent and general reducing agent.

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

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.
