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)

T53.5 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 effects of chlorofluorocarbons. 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 effects of chlorofluorocarbons

Non-specific codes like T53.5 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 effects of chlorofluorocarbons:

  • T53.5X for Toxic effects of chlorofluorocarbons - NON-BILLABLE CODE

  • T53.5X1 for Toxic effect of chlorofluorocarbons, accidental (unintentional) - NON-BILLABLE CODE

  • Use T53.5X1A for initial encounter - BILLABLE CODE

  • Use T53.5X1D for subsequent encounter - BILLABLE CODE

  • Use T53.5X1S for sequela - BILLABLE CODE

  • T53.5X2 for Toxic effect of chlorofluorocarbons, intentional self-harm - NON-BILLABLE CODE

  • Use T53.5X2A for initial encounter - BILLABLE CODE

  • Use T53.5X2D for subsequent encounter - BILLABLE CODE

  • Use T53.5X2S for sequela - BILLABLE CODE

  • T53.5X3 for Toxic effect of chlorofluorocarbons, assault - NON-BILLABLE CODE

  • Use T53.5X3A for initial encounter - BILLABLE CODE

  • Use T53.5X3D for subsequent encounter - BILLABLE CODE

  • Use T53.5X3S for sequela - BILLABLE CODE

  • T53.5X4 for Toxic effect of chlorofluorocarbons, undetermined - NON-BILLABLE CODE

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

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

  • Use T53.5X4S for sequela - BILLABLE CODE

Coding Guidelines

When a harmful substance is ingested or comes in contact with a person, this is classified as a toxic effect. Toxic effect codes have an associated intent: accidental, intentional self-harm, assault and undetermined.

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
