Code Navigator:

T36.7X2S is a billable diagnosis code used to specify a medical diagnosis of poisoning by antifungal antibiotics, systemically used, intentional self-harm, 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.

T36.7X2S 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 antifungal antibiotics systemically used intentional self-harm. 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.

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: MBD034

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.

CCSR Code: INJ075

Inpatient Default: N - Not default inpatient assignment for principal diagnosis or first-listed diagnosis.

Outpatient Default: N - Not default outpatient assignment for principal diagnosis or first-listed diagnosis.

• Amphotericin B

macrolide antifungal antibiotic produced by streptomyces nodosus obtained from soil of the orinoco river region of venezuela.

• Griseofulvin

an antifungal agent used in the treatment of tinea infections.

• Mepartricin

polyene macrolide antibiotic with unknown composition. it is obtained from streptomyces aureofaciens. it is used as an antifungal agent, an antiprotozoal agent, and in the treatment of benign prostatic hypertrophy.

• Nystatin

macrolide antifungal antibiotic complex produced by streptomyces noursei, s. aureus, and other streptomyces species. the biologically active components of the complex are nystatin a1, a2, and a3.

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

T36.7X2S 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: E959

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 T36.7X2 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.

Self-Harm

What is self-harm?

Self-harm, or self-injury, is when a person hurts his or her own body on purpose. The injuries may be minor, but sometimes they can be severe. They may leave permanent scars or cause serious health problems. Some examples are:

• Cutting yourself (such as using a razor blade, knife, or other sharp object to cut your skin)
• Punching yourself or punching things (like a wall)
• Burning yourself with cigarettes, matches, or candles
• Pulling out your hair
• Poking objects through body openings
• Breaking your bones or bruising yourself

Self-harm is not a mental disorder. It is a behavior - an unhealthy way to cope with strong feelings. However, some of the people who harm themselves do have a mental disorder.

People who harm themselves are usually not trying to attempt suicide. But they are at higher risk of attempting suicide if they do not get help.

Why do people harm themselves?

There are different reasons why people harm themselves. Often, they have trouble coping and dealing with their feelings. They harm themselves to try to:

• Make themselves feel something (because they feel empty or numb inside)
• Block upsetting memories
• Show that they need help
• Release strong feelings that overwhelm them, such as anger, loneliness, or hopelessness
• Punish themselves
• Feel a sense of control

Who is at risk for self-harm?

There are people of all ages who harm themselves, but it usually starts in the teen or early adult years. Self-harm is more common in people who:

• Were abused or went through a trauma as children
• Have mental disorders, such as
  • Depression
  • Eating disorders
  • Post-traumatic stress disorder
  • Certain personality disorders
• Misuse drugs or alcohol
• Have friends who self-harm
• Have low self-esteem

What are the signs of self-harm?

Signs that someone may be hurting themselves include:

• Having frequent cuts, bruises, or scars
• Wearing long sleeves or pants even in hot weather
• Making excuses about injuries
• Having sharp objects around for no clear reason

How can I help someone who self-harms?

If someone you know is self-harming, it is important not to be judgmental. Let that person know that you want to help. If the person is a child or teenager, ask him or her to talk to a trusted adult. If he or she won't do that, talk to a trusted adult yourself. If the person who is self-harming is an adult, suggest mental health counseling.

What the treatments are for self-harm?

There are no medicines to treat self-harming behaviors. But there are medicines to treat any mental disorders that the person may have, such as anxiety and depression. Treating the mental disorder may weaken the urge to self-harm.

Mental health counseling or therapy can also help by teaching the person:

• Problem-solving skills
• New ways to cope with strong emotions
• Better relationship skills
• Ways to strengthen self-esteem

If the problem is severe, the person may need more intensive treatment in a psychiatric hospital or a mental health day program.
