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 other noxious substances eaten as food
        (T62)

T62.94XD is a billable diagnosis code used to specify a medical diagnosis of toxic effect of unspecified noxious substance eaten as food, undetermined, subsequent encounter. 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.

T62.94XD is a subsequent encounter code, includes a 7th character and should be used after the patient has completed active treatment for a condition like toxic effect of unspecified noxious substance eaten as food undetermined. According to ICD-10-CM Guidelines a "subsequent encounter" occurs when the patient is receiving routine care for the condition during the healing or recovery phase of treatment. Subsequent diagnosis codes are appropriate during the recovery phase, no matter how many times the patient has seen the provider for this condition. If the provider needs to adjust the patient's care plan due to a setback or other complication, the encounter becomes active again.

Unspecified diagnosis codes like T62.94XD are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Approximate Synonyms

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

  • Allergic urticaria due to ingested food

Clinical Classification

Coding Guidelines

The appropriate 7th character is to be added to each code from block Toxic effect of other noxious substances eaten as food (T62). Use the following options for the aplicable episode of care:

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

Present on Admission (POA)

T62.94XD 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 T62.94XD to ICD-9-CM

  • ICD-9-CM Code: V58.89 - Other specfied aftercare
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Table of Drugs and Chemicals

The parent code T62.94 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.

Patient Education


Foodborne Illness

Each year, around 48 million people in the United States get sick from contaminated food. Common causes include bacteria and viruses. Less often, the cause may be a parasite or a harmful chemical, such as a high amount of pesticides. Symptoms of foodborne illness depend on the cause. They can be mild or serious. They usually include:

  • Upset stomach
  • Abdominal cramps
  • Nausea and vomiting
  • Diarrhea
  • Fever
  • Dehydration

Most foodborne illnesses are acute. This means that they happen suddenly and last a short time.

It takes several steps to get food from the farm or fishery to your dining table. Contamination can happen during any of these steps. For example, it can happen to:

  • Raw meat during slaughter
  • Fruits and vegetables when they are growing or when they are processed
  • Refrigerated foods when they are left on a loading dock in warm weather

But it can also happen in your kitchen if you leave food out for more than 2 hours at room temperature. Handling food safely can help prevent foodborne illnesses.

Most people with foodborne illness get better on their own. It is important to replace lost fluids and electrolytes to prevent dehydration. If your health care provider can diagnose the specific cause, you may get medicines such as antibiotics to treat it. For more serious illness, you may need treatment at a hospital.

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.
