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 aflatoxin and other mycotoxin food contaminants
        (T64)

T64.81XS is a billable diagnosis code used to specify a medical diagnosis of toxic effect of other mycotoxin food contaminants, accidental (unintentional), sequela. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

T64.81XS is a sequela code, includes a 7th character and should be used for complications that arise as a direct result of a condition like toxic effect of other mycotoxin food contaminants accidental (unintentional). According to ICD-10-CM Guidelines a "sequela" code should be used for chronic or residual conditions that are complications of an initial acute disease, illness or injury. The most common sequela is pain. Usually, two diagnosis codes are needed when reporting sequela. The first code describes the nature of the sequela while the second code describes the sequela or late effect.

Approximate Synonyms

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

  • Accidental exposure to mycotoxin
  • Accidental exposure to mycotoxin T2
  • Alimentary toxic aleukia
  • Aspergillus clavatus tremors
  • Aspergillus versicolor toxicosis
  • Ergotism
  • Ergotism
  • Gangrenous ergotism
  • Myrotheciotoxicosis
  • Ochratoxicosis
  • Penicillium cyclopium toxicosis
  • Penicillium purpurogenum toxicosis
  • Poisoning by ergot alkaloid
  • Spasmodic ergotism
  • Toxic effect of mycotoxin
  • Tricothecium toxicosis

Clinical Classification

Clinical Information

  • Ergotism

    poisoning caused by ingesting ergotized grain or by the misdirected or excessive use of ergot as a medicine.

Coding Guidelines

The appropriate 7th character is to be added to each code from block Toxic effect of aflatoxin and other mycotoxin food contaminants (T64). Use the following options for the aplicable episode of care:

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

Present on Admission (POA)

T64.81XS is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

Convert T64.81XS to ICD-9-CM

  • ICD-9-CM Code: 909.1 - Late eff nonmed substanc
    Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment.
  • ICD-9-CM Code: E929.2 - Late eff acc poisoning
    Combination Flag - Multiple codes are needed to describe the source diagnosis code. Correct coding should be done based on contextual judgment.

Table of Drugs and Chemicals

The parent code T64.81 of the current diagnosis 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.

Molds

Molds are fungi that can be found both outdoors and indoors. They grow best in warm, damp and humid conditions. If you have damp or wet spots in your house, you will probably get mold.

Molds can cause health problems. Inhaling or touching mold or mold spores may cause allergic reactions or asthma attacks in sensitive people. Molds can cause fungal infections. In addition, mold exposure may irritate your eyes, skin, nose, throat, and lungs.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
