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 halogen derivatives of aliphatic and aromatic hydrocarbons
        (T53)

T53.5X4 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 chlorofluorocarbons, 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 chlorofluorocarbons, undetermined

Non-specific codes like T53.5X4 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 chlorofluorocarbons, undetermined:

  • Use T53.5X4A for initial encounter - BILLABLE CODE

  • Use T53.5X4D for subsequent encounter - BILLABLE CODE

  • Use T53.5X4S for sequela - BILLABLE CODE

Clinical Information

  • Chlorofluorocarbons

    a series of hydrocarbons containing both chlorine and fluorine. these have been used as refrigerants, blowing agents, cleaning fluids, solvents, and as fire extinguishing agents. they have been shown to cause stratospheric ozone depletion and have been banned for many uses.
  • Chlorofluorocarbons, Ethane

    a group of ethane-based halogenated hydrocarbons containing one or more fluorine and chlorine atoms.
  • Chlorofluorocarbons, Methane

    a group of methane-based halogenated hydrocarbons containing one or more fluorine and chlorine atoms.

Coding Guidelines

The appropriate 7th character is to be added to each code from block Toxic effect of halogen derivatives of aliphatic and aromatic hydrocarbons (T53). 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.
