ICD-10 Code for:

Poisoning by chloramphenicol group, accidental

Is Billable?

Not Valid for Submission

Code Navigator:

T36.2X1 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity from the list below for a diagnosis of poisoning by chloramphenicol group, accidental (unintentional). The code is not specific and is NOT valid for the year 2026 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.

Non-specific codes like T36.2X1 require more digits to indicate the appropriate level of specificity. Consider using any of the following billable codes with a higher level of specificity when coding for poisoning by chloramphenicol group, accidental:

Use T36.2X1A for initial encounter

Use T36.2X1D for subsequent encounter

Use T36.2X1S for sequela

The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

• Accidental chloramphenicol overdose

• Accidental chloramphenicol poisoning

• Chloramphenicol overdose

• Poisoning by chloramphenicol

• Poisoning by thiamphenicol

• Chloramphenicol

an antibiotic first isolated from cultures of streptomyces venequelae in 1947 but now produced synthetically. it has a relatively simple structure and was the first broad-spectrum antibiotic to be discovered. it acts by interfering with bacterial protein synthesis and is mainly bacteriostatic. (from martindale, the extra pharmacopoeia, 29th ed, p106)

• Chloramphenicol O-Acetyltransferase

an enzyme that catalyzes the acetylation of chloramphenicol to yield chloramphenicol 3-acetate. since chloramphenicol 3-acetate does not bind to bacterial ribosomes and is not an inhibitor of peptidyltransferase, the enzyme is responsible for the naturally occurring chloramphenicol resistance in bacteria. the enzyme, for which variants are known, is found in both gram-negative and gram-positive bacteria. ec 2.3.1.28.

• Chloramphenicol Resistance

nonsusceptibility of bacteria to the action of chloramphenicol, a potent inhibitor of protein synthesis in the 50s ribosomal subunit where amino acids are added to nascent bacterial polypeptides.

• Thiamphenicol

a methylsulfonyl analog of chloramphenicol. it is an antibiotic and immunosuppressive agent.

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 systemic antibiotics (T36). Use the following options for the aplicable episode of care:

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

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.

Antibiotics

What are antibiotics?

Antibiotics are medicines that fight bacterial infections in people and animals. They work by killing the bacteria or by making it hard for the bacteria to grow and multiply.

Antibiotics can be taken in different ways:

• Orally (by mouth). This could be pills, capsules, or liquids.
• Topically. This might be a cream, spray, or ointment that you put on your skin. It could also be eye ointment, eye drops, or ear drops.
• Through an injection or intravenously (IV). This is usually for more serious infections.

What do antibiotics treat?

Antibiotics only treat certain bacterial infections, such as strep throat, urinary tract infections, and E. coli.

You may not need to take antibiotics for some bacterial infections. For example, you might not need them for many sinus infections or some ear infections. Taking antibiotics when they're not needed won't help you, and they can have side effects. Your health care provider can decide the best treatment for you when you're sick. Don't ask your provider to prescribe an antibiotic for you.

Do antibiotics treat viral infections?

Antibiotics do not work on viral infections. For example, you shouldn't take antibiotics for:

• Colds and runny noses, even if the mucus is thick, yellow, or green
• Most sore throats (except strep throat)
• Flu
• Most cases of bronchitis

What are the side effects of antibiotics?

The side effects of antibiotics range from minor to very severe. Some of the common side effects include:

• Rash
• Nausea
• Diarrhea
• Yeast infections

More serious side effects can include:

• C. diff infections, which cause diarrhea that can lead to severe colon damage and sometimes even death
• Severe and life-threatening allergic reactions
• Antibiotic resistance infections

Call your health care provider if you develop any side effects while taking your antibiotic.

Why is it important to take antibiotics only when they're needed?

You should only take antibiotics when they are needed because they can cause side effects and can contribute to antibiotic resistance. Antibiotic resistance happens when the bacteria change and become able to resist the effects of an antibiotic. This means that the bacteria continue to grow.

How do I use antibiotics correctly?

When you take antibiotics, it is important that you take them responsibly:

• Always follow the directions carefully. Finish your medicine even if you feel better. If you stop taking them too soon, some bacteria may survive and re-infect you.
• Don't save your antibiotics for later.
• Don't share your antibiotic with others.
• Don't take antibiotics prescribed for someone else. This may delay the best treatment for you, make you even sicker, or cause side effects.

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?
