Poisoning by aminoglycosides, undetermined

ICD-10-CM Code:

T36.5X4

ICD-10 Code for:

Poisoning by aminoglycosides, undetermined

Is Billable?

Not Valid for Submission

Code Navigator:

T36.5X4 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 aminoglycosides, undetermined. 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 T36.5X4 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 aminoglycosides, undetermined:

Use T36.5X4A for initial encounter

Use T36.5X4D for subsequent encounter

Use T36.5X4S for sequela

• Injury, poisoning and certain other consequences of external causes

  • Poisoning by, adverse effect of and underdosing of drugs, medicaments and biological substances
    T36-T50
    * Poisoning by, adverse effect of and underdosing of systemic antibiotics
    T36

• Amikacin

a broad-spectrum antibiotic derived from kanamycin. it is reno- and oto-toxic like the other aminoglycoside antibiotics.

• Kanamycin Kinase

a class of enzymes that inactivate aminocyclitol-aminoglycoside antibiotics (aminoglycosides) by regiospecific phosphorylation of the 3' and/or 5' hydroxyl.

• Dibekacin

analog of kanamycin with antitubercular as well as broad-spectrum antimicrobial properties.

• Framycetin

a component of neomycin that is produced by streptomyces fradiae. on hydrolysis it yields neamine and neobiosamine b. (from merck index, 11th ed)

• Kanamycin

antibiotic complex produced by streptomyces kanamyceticus from japanese soil. comprises 3 components: kanamycin a, the major component, and kanamycins b and c, the minor components.

• Kanamycin Resistance

nonsusceptibility of bacteria to the antibiotic kanamycin, which can bind to their 70s ribosomes and cause misreading of messenger rna.

• Netilmicin

semisynthetic 1-n-ethyl derivative of sisomycin, an aminoglycoside antibiotic with action similar to gentamicin, but less ear and kidney toxicity.

• Novobiocin

an antibiotic compound derived from streptomyces niveus. it has a chemical structure similar to coumarin. novobiocin binds to dna gyrase, and blocks adenosine triphosphatase (atpase) activity. (from reynolds, martindale the extra pharmacopoeia, 30th ed, p189)

• Paromomycin

an aminoglycoside antibacterial and antiprotozoal agent produced by species of streptomyces.

• Ribostamycin

a broad-spectrum antimicrobial isolated from streptomyces ribosifidicus.

• Sisomicin

antibiotic produced by micromonospora inyoensis. it is closely related to gentamicin c1a, one of the components of the gentamicin complex (gentamicins).

• Spectinomycin

an antibiotic produced by streptomyces spectabilis. it is active against gram-negative bacteria and used for the treatment of gonorrhea.

• Tobramycin

an aminoglycoside, broad-spectrum antibiotic produced by streptomyces tenebrarius. it is effective against gram-negative bacteria, especially the pseudomonas species. it is a 10% component of the antibiotic complex, nebramycin, produced by the same species.

• Tobramycin, Dexamethasone Drug Combination

a topical preparation of tobramycin and dexamethasone that is used for treating or preventing superficial bacterial infections of the eye.

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.

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.
