Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Poisoning by, adverse effect of and underdosing of drugs, medicaments and biological substances
      (T36-T50)
      • Poisoning by, adverse effect of and underdosing of diuretics and other and unspecified drugs, medicaments and biological substances
        (T50)

T50.6X2D is a billable diagnosis code used to specify a medical diagnosis of poisoning by antidotes and chelating agents, intentional self-harm, 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.

T50.6X2D is a subsequent encounter code, includes a 7th character and should be used after the patient has completed active treatment for a condition like poisoning by antidotes and chelating agents intentional self-harm. 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.

Approximate Synonyms

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

Clinical Information

  • Cysteamine

    a mercaptoethylamine compound that is endogenously derived from the coenzyme a degradative pathway. the fact that cysteamine is readily transported into lysosomes where it reacts with cystine to form cysteine-cysteamine disulfide and cysteine has led to its use in cystine depleting agents for the treatment of cystinosis.
  • Disulfiram

    a carbamate derivative used as an alcohol deterrent. it is a relatively nontoxic substance when administered alone, but markedly alters the intermediary metabolism of alcohol. when alcohol is ingested after administration of disulfiram, blood acetaldehyde concentrations are increased, followed by flushing, systemic vasodilation, respiratory difficulties, nausea, hypotension, and other symptoms (acetaldehyde syndrome). it acts by inhibiting aldehyde dehydrogenase.
  • Glutathione

    a tripeptide with many roles in cells. it conjugates to drugs to make them more soluble for excretion, is a cofactor for some enzymes, is involved in protein disulfide bond rearrangement and reduces peroxides.
  • Glutathione Disulfide

    a glutathione dimer formed by a disulfide bond between the cysteine sulfhydryl side chains during the course of being oxidized.
  • Glutathione Peroxidase

    an enzyme catalyzing the oxidation of 2 moles of glutathione in the presence of hydrogen peroxide to yield oxidized glutathione and water.
  • Glutathione Peroxidase GPX1

    one of the most abundant isoenzymes of the glutathione peroxidase family. located in the cytosol and mitochondria, it catalyzes the reduction of hydrogen peroxide to water, functioning to limit the accumulation of hydrogen peroxide and modulating processes that utilize hydrogen peroxide; and also the reduction of other organic hydroperoxides to their corresponding alcohols.
  • Glutathione Reductase

    catalyzes the oxidation of glutathione to glutathione disulfide in the presence of nadp+. deficiency in the enzyme is associated with hemolytic anemia. formerly listed as ec 1.6.4.2.
  • Glutathione S-Transferase pi

    a glutathione transferase that catalyzes the conjugation of electrophilic substrates to glutathione. this enzyme has been shown to provide cellular protection against redox-mediated damage by free radicals.
  • Glutathione Synthase

    one of the enzymes active in the gamma-glutamyl cycle. it catalyzes the synthesis of glutathione from gamma-glutamylcysteine and glycine in the presence of atp with the formation of adp and orthophosphate. ec 6.3.2.3.
  • Glutathione Transferase

    a transferase that catalyzes the addition of aliphatic, aromatic, or heterocyclic free radicals as well as epoxides and arene oxides to glutathione. addition takes place at the sulfur. it also catalyzes the reduction of polyol nitrate by glutathione to polyol and nitrite.
  • Lactoylglutathione Lyase

    an enzyme that catalyzes the interconversion of methylglyoxal and lactate, with glutathione serving as a coenzyme. ec 4.4.1.5.
  • Phospholipid Hydroperoxide Glutathione Peroxidase

    a selenoenzyme that converts glutathione plus fatty acid hydroperoxides to glutathione disulfide plus hydroxy fatty acids and water.
  • Protein Disulfide Reductase (Glutathione)

    an enzyme that catalyzes the reduction of a protein-disulfide in the presence of glutathione, forming a protein-dithiol. insulin is one of its substrates. ec 1.8.4.2.
  • Obidoxime Chloride

    cholinesterase reactivator occurring in two interchangeable isomeric forms, syn and anti.
  • Penicillamine

    3-mercapto-d-valine. the most characteristic degradation product of the penicillin antibiotics. it is used as an antirheumatic and as a chelating agent in wilson's disease.

Coding Guidelines

When coding a poisoning or reaction to the improper use of a medication (e.g., overdose, wrong substance given or taken in error, wrong route of administration), first assign the appropriate code from categories T36-T50. The poisoning codes have an associated intent as their 5th or 6th character (accidental, intentional self-harm, assault and undetermined. If the intent of the poisoning is unknown or unspecified, code the intent as accidental intent. The undetermined intent is only for use if the documentation in the record specifies that the intent cannot be determined. Use additional code(s) for all manifestations of poisonings.

The appropriate 7th character is to be added to each code from block Poisoning by, adverse effect of and underdosing of diuretics and other and unspecified drugs, medicaments and biological substances (T50). Use the following options for the aplicable episode of care:

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

Present on Admission (POA)

T50.6X2D 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 T50.6X2D 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 T50.6X2 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


Poisoning

A poison is any substance that is harmful to your body. You might swallow it, inhale it, inject it, or absorb it through your skin. Any substance can be poisonous if too much is taken. Poisons can include:

  • Prescription or over-the-counter medicines taken in doses that are too high
  • Overdoses of illegal drugs
  • Carbon monoxide from gas appliances
  • Household products, such as laundry powder or furniture polish
  • Pesticides
  • Indoor or outdoor plants
  • Metals such as lead and mercury

The effects of poisoning range from short-term illness to brain damage, coma, and death. To prevent poisoning it is important to use and store products exactly as their labels say. Keep dangerous products where children can't get to them. Treatment for poisoning depends on the type of poison. If you suspect someone has been poisoned, call your local poison control center at 1-800-222-1222 right away.

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.
