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 corrosive substances
        (T54)

T54.2X1 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 corrosive acids and acid-like substances, accidental (unintentional). 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 corrosive acids and acid-like substnc, acc

Non-specific codes like T54.2X1 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 corrosive acids and acid-like substnc, acc:

  • Use T54.2X1A for initial encounter - BILLABLE CODE

  • Use T54.2X1D for subsequent encounter - BILLABLE CODE

  • Use T54.2X1S for sequela - BILLABLE CODE

Clinical Information

  • Oxalates

    derivatives of oxalic acid. included under this heading are a broad variety of acid forms, salts, esters, and amides that are derived from the ethanedioic acid structure.
  • 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 corrosive substances (T54). Use the following options for the aplicable episode of care:

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

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Toxic effects of corrosive acids and acid-like substances NOS

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.
