Code Navigator:
T36.0X3S is a billable diagnosis code used to specify a medical diagnosis of poisoning by penicillins, assault, sequela. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2025 through September 30, 2026. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
T36.0X3S is a sequela code, includes a 7th character and should be used for complications that arise as a direct result of a condition like poisoning by penicillins assault. According to ICD-10-CM Guidelines a "sequela" code should be used for chronic or residual conditions that are complications of an initial acute disease, illness or injury. The most common sequela is pain. Usually, two diagnosis codes are needed when reporting sequela. The first code describes the nature of the sequela while the second code describes the sequela or late effect.

S00–T88
Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.
They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.
CCSR Code: INJ075
Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.
Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.
Amoxicillin
a broad-spectrum semisynthetic antibiotic similar to ampicillin except that its resistance to gastric acid permits higher serum levels with oral administration.
Amoxicillin-Potassium Clavulanate Combination
a fixed-ratio combination of amoxicillin trihydrate and potassium clavulanate.
Ampicillin
semi-synthetic derivative of penicillin that functions as an orally active broad-spectrum antibiotic.
Ampicillin Resistance
nonsusceptibility of a microbe to the action of ampicillin, a penicillin derivative that interferes with cell wall synthesis.
Pivampicillin
pivalate ester analog of ampicillin.
Talampicillin
an ester of ampicillin which is readily hydrolyzed on absorption to release ampicillin. it is well absorbed from the gastrointestinal tract resulting in a greater bioavailability of ampicillin than can be achieved with equivalent doses of ampicillin.
Azlocillin
a semisynthetic ampicillin-derived acylureido penicillin.
Carbenicillin
broad-spectrum semisynthetic penicillin derivative used parenterally. it is susceptible to gastric juice and penicillinase and may damage platelet function.
Carfecillin
the phenyl ester of carbenicillin that, upon oral administration, is broken down in the intestinal mucosa to the active antibacterial. it is used for urinary tract infections.
Penicillinase
a beta-lactamase preferentially cleaving penicillins. (dorland, 28th ed) ec 3.5.2.-.
Cloxacillin
a semi-synthetic antibiotic that is a chlorinated derivative of oxacillin.
Cyclacillin
a cyclohexylamido analog of penicillanic acid.
Dicloxacillin
one of the penicillins which is resistant to penicillinase.
Cilastatin, Imipenem Drug Combination
combination of imipenem and cilastatin that is used in the treatment of bacterial infections; cilastatin inhibits renal dehydropeptidase i to prolong the half-life and increase the tissue penetration of imipenem, enhancing its efficacy as an anti-bacterial agent.
Imipenem
semisynthetic thienamycin that has a wide spectrum of antibacterial activity against gram-negative and gram-positive aerobic and anaerobic bacteria, including many multiresistant strains. it is stable to beta-lactamases. clinical studies have demonstrated high efficacy in the treatment of infections of various body systems. its effectiveness is enhanced when it is administered in combination with cilastatin, a renal dipeptidase inhibitor.
Methicillin
one of the penicillins which is resistant to penicillinase but susceptible to a penicillin-binding protein. it is inactivated by gastric acid so administered by injection.
Methicillin Resistance
non-susceptibility of a microbe to the action of methicillin, a semi-synthetic penicillin derivative.
Methicillin-Resistant Staphylococcus aureus
a strain of staphylococcus aureus that is non-susceptible to the action of methicillin. the mechanism of resistance usually involves modification of normal or the presence of acquired penicillin binding proteins.
Mezlocillin
semisynthetic ampicillin-derived acylureido penicillin. it has been proposed for infections with certain anaerobes and may be useful in inner ear, bile, and cns infections.
Nafcillin
a semi-synthetic antibiotic related to penicillin.
Oxacillin
an antibiotic similar to flucloxacillin used in resistant staphylococci infections.
Piperacillin
semisynthetic, broad-spectrum, ampicillin derived ureidopenicillin antibiotic proposed for pseudomonas infections. it is also used in combination with other antibiotics.
Piperacillin, Tazobactam Drug Combination
an antibiotic combination product of piperacillin and tazobactam, a penicillanic acid derivative with enhanced beta-lactamase inhibitory activity, that is used for the intravenous treatment of intra-abdominal, pelvic, and skin infections and for community-acquired pneumonia of moderate severity. it is also used for the treatment of pseudomonas aeruginosa infections.
Sulbactam
a beta-lactamase inhibitor with very weak antibacterial action. the compound prevents antibiotic destruction of beta-lactam antibiotics by inhibiting beta-lactamases, thus extending their spectrum activity. combinations of sulbactam with beta-lactam antibiotics have been used successfully for the therapy of infections caused by organisms resistant to the antibiotic alone.
Sulbenicillin
semisynthetic penicillin-type antibiotic.
Ticarcillin
an antibiotic derived from penicillin similar to carbenicillin in action.
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
T36.0X3S 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.

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.
ICD-9-CM: 909.0
Approximate Flag - The approximate mapping means this ICD-10 code does not have an exact ICD-9 equivalent. The matched code is the closest available option, but it may not fully capture the original diagnosis or clinical intent.
ICD-9-CM: E969
Approximate Flag - The approximate mapping means this ICD-10 code does not have an exact ICD-9 equivalent. The matched code is the closest available option, but it may not fully capture the original diagnosis or clinical intent.
The parent code T36.0X3 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.

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.
