Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • 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)

T36.7X6 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of underdosing of antifungal antibiotics, systemically used. 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 Underdosing of antifungal antibiotics, systemically used

Non-specific codes like T36.7X6 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 underdosing of antifungal antibiotics, systemically used:

  • Use T36.7X6A for initial encounter - BILLABLE CODE

  • Use T36.7X6D for subsequent encounter - BILLABLE CODE

  • Use T36.7X6S for sequela - BILLABLE CODE

Clinical Information

  • 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.

Coding Guidelines

Underdosing refers to taking less of a medication than is prescribed by a provider or a manufacturer's instruction. Codes for underdosing should never be assigned as principal or first-listed codes. If a patient has a relapse or exacerbation of the medical condition for which the drug is prescribed because of the reduction in dose, then the medical condition itself should be coded.

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

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


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.
