        (T50)

T50.Z11 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of poisoning by immunoglobulin, 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 Poisoning by immunoglobulin, accidental (unintentional)

Non-specific codes like T50.Z11 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 poisoning by immunoglobulin, accidental (unintentional):

  • Use T50.Z11A for initial encounter - BILLABLE CODE

  • Use T50.Z11D for subsequent encounter - BILLABLE CODE

  • Use T50.Z11S 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 excessive dose of antiserum administered
  • Accidental excessive dose of gamma globulin administered
  • Excessive dose of antiserum administered
  • Excessive dose of gamma globulin administered

Clinical Information

  • Diphtheria

    a localized infection of mucous membranes or skin caused by toxigenic strains of corynebacterium diphtheriae. it is characterized by the presence of a pseudomembrane at the site of infection. diphtheria toxin, produced by c. diphtheriae, can cause myocarditis, polyneuritis, and other systemic toxic effects.
  • Diphtheria Antitoxin

    an antitoxin produced against the toxin of corynebacterium diphtheriae that is used for the treatment of diphtheria.
  • Diphtheria Toxin

    an adp-ribosylating polypeptide produced by corynebacterium diphtheriae that causes the signs and symptoms of diphtheria. it can be broken into two unequal domains: the smaller, catalytic a domain is the lethal moiety and contains mono(adp-ribose) transferases which transfers adp ribose to peptide elongation factor 2 thereby inhibiting protein synthesis; and the larger b domain that is needed for entry into cells.
  • Diphtheria Toxoid

    the formaldehyde-inactivated toxin of corynebacterium diphtheriae. it is generally used in mixtures with tetanus toxoid and pertussis vaccine; (dtp); or with tetanus toxoid alone (dt for pediatric use and td, which contains 5- to 10-fold less diphtheria toxoid, for other use). diphtheria toxoid is used for the prevention of diphtheria; diphtheria antitoxin is for treatment.
  • Diphtheria-Tetanus Vaccine

    a combined vaccine used to prevent infection with diphtheria and tetanus toxoid. this is used in place of dtp vaccine (diphtheria-tetanus-pertussis vaccine) when pertussis vaccine is contraindicated.
  • Diphtheria-Tetanus-acellular Pertussis Vaccines

    combined vaccines consisting of diphtheria toxoid; tetanus toxoid; and an acellular form of pertussis vaccine. at least five different purified antigens of b. pertussis have been used in various combinations in these vaccines.
  • Diphtheria-Tetanus-Pertussis Vaccine

    a vaccine consisting of diphtheria toxoid; tetanus toxoid; and whole-cell pertussis vaccine. the vaccine protects against diphtheria, tetanus, and whooping cough.
  • Fowlpox

    a poxvirus infection of poultry and other birds characterized by the formation of wart-like nodules on the skin and diphtheritic necrotic masses (cankers) in the upper digestive and respiratory tracts.
  • Heparin-binding EGF-like Growth Factor

    an egf family member that is expressed in a variety of hematopoietic, endothelial, vascular smooth muscle, and epithelial cells. it is synthesized as a transmembrane protein which is cleaved by proteases to produce the secreted form of the protein which has specificity for the egf receptor and the erbb-4 receptor. the membrane-bound form of the protein has been identified as the receptor which binds to and allows diphtheria toxin to enter cells.
  • Hepatitis B

    inflammation of the liver in humans caused by a member of the orthohepadnavirus genus, hepatitis b virus. it is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.
  • Hepatitis B Antibodies

    antibodies to the hepatitis b antigens, including antibodies to the surface (australia) and core of the dane particle and those to the "e" antigens.
  • Hepatitis B Antigens

    antigens of the virion of the hepatitis b virus or the dane particle, its surface (hepatitis b surface antigens), core (hepatitis b core antigens), and other associated antigens, including the hepatitis b e antigens.
  • Hepatitis B Core Antigens

    the hepatitis b antigen within the core of the dane particle, the infectious hepatitis virion.
  • Hepatitis B e Antigens

    a closely related group of antigens found in the plasma only during the infective phase of hepatitis b or in virulent chronic hepatitis b, probably indicating active virus replication; there are three subtypes which may exist in a complex with immunoglobulins g.
  • Hepatitis B Surface Antigens

    those hepatitis b antigens found on the surface of the dane particle and on the 20 nm spherical and tubular particles. several subspecificities of the surface antigen are known. these were formerly called the australia antigen.
  • Hepatitis B Vaccines

    vaccines or candidate vaccines containing inactivated hepatitis b or some of its component antigens and designed to prevent hepatitis b. some vaccines may be recombinantly produced.
  • Hepatitis B virus

    the type species of the genus orthohepadnavirus which causes human hepatitis b and is also apparently a causal agent in human hepatocellular carcinoma. the dane particle is an intact hepatitis virion, named after its discoverer. non-infectious spherical and tubular particles are also seen in the serum.
  • Hepatitis B Virus, Duck

    a dna virus that closely resembles human hepatitis b virus. it has been recovered from naturally infected ducks.
  • Hepatitis B Virus, Woodchuck

    an orthohepadnavirus causing chronic liver disease and hepatocellular carcinoma in woodchucks. it closely resembles the human hepatitis b virus.
  • Hepatitis B, Chronic

    inflammation of the liver in humans caused by hepatitis b virus lasting six months or more. it is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.
  • Orthohepadnavirus

    a genus of hepadnaviridae causing hepatitis in humans, woodchucks (hepatitis b virus, woodchuck) and ground squirrels. hepatitis b virus is the type species.
  • Rabies

    acute viral cns infection affecting mammals, including humans. it is caused by rabies virus and usually spread by contamination with virus-laden saliva of bites inflicted by rabid animals. important animal vectors include the dog, cat, bat, fox, raccoon, skunk, and wolf.
  • Rabies Vaccines

    vaccines or candidate vaccines used to prevent and treat rabies. the inactivated virus vaccine is used for preexposure immunization to persons at high risk of exposure, and in conjunction with rabies immunoglobulin, for postexposure prophylaxis.
  • Rabies virus

    the type species of lyssavirus causing rabies in humans and other animals. transmission is mostly by animal bites through saliva. the virus is neurotropic multiplying in neurons and myotubes of vertebrates.

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

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.

Patient Education


Medication Errors

Medicines treat infectious diseases, prevent problems from chronic diseases, and ease pain. But medicines can also cause harmful reactions if not used correctly. Errors can happen in the hospital, at the health care provider's office, at the pharmacy, or at home. You can help prevent errors by:

  • Knowing your medicines. When you get a prescription, ask the name of the medicine and check to make sure that the pharmacy gave you the right medicine. Make sure that you understand how often you should take the medicine and how long you should take it.
  • Keeping a list of medicines.
    • Write down all of the medicines that you are taking, including the names of your medicines, how much you take, and when you take them. Make sure to include any over-the-counter medicines, vitamins, supplements, and herbs that you take.
    • List the medicines that you are allergic to or that have caused you problems in the past.
    • Take this list with you every time you see a health care provider.
  • Reading medicine labels and following the directions. Don't just rely on your memory - read the medication label every time. Be especially careful when giving medicines to children.
  • Asking questions. If you don't know the answers to these questions, ask your health care provider or pharmacist:
    • Why am I taking this medicine?
    • What are the common side effects?
    • What should I do if I have side effects?
    • When should I stop this medicine?
    • Can I take this medicine with the other medicines and supplements on my list?
    • Do I need to avoid certain foods or alcohol while taking this medicine?
