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 alcohol
        (T51)

T51.1X1 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 methanol, 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 methanol, accidental (unintentional)

Non-specific codes like T51.1X1 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 methanol, accidental (unintentional):

  • Use T51.1X1A for initial encounter - BILLABLE CODE

  • Use T51.1X1D for subsequent encounter - BILLABLE CODE

  • Use T51.1X1S 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:

  • Accidental poisoning by denatured alcohol
  • Accidental poisoning by methyl alcohol
  • Accidental poisoning by methylated spirit
  • Accidental poisoning with ethyl alcohol
  • Adverse reaction to ethanol
  • Industrial methylated spirit adverse reaction
  • Metabolic acidosis due to methanol
  • Methanol retinopathy
  • Methyl alcohol causing toxic effect
  • Toxic effect of denatured alcohol

Coding Guidelines

The appropriate 7th character is to be added to each code from block Toxic effect of alcohol (T51). 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 effect of methanol 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.
