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 other systemic anti-infectives and antiparasitics
        (T37)

T37.8X6S is a billable diagnosis code used to specify a medical diagnosis of underdosing of other specified systemic anti-infectives and antiparasitics, sequela. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

This code describes a circumstance which influences the patient's health status but not a current illness or injury. The code is unacceptable as a principal diagnosis.

T37.8X6S is a sequela code, includes a 7th character and should be used for complications that arise as a direct result of a condition like underdosing of other specified systemic anti-infectives and antiparasitics. 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 Classification

Clinical Information

  • Bithionol

    halogenated anti-infective agent that is used against trematode and cestode infestations.

  • Hydroxychloroquine

    a chemotherapeutic agent that acts against erythrocytic forms of malarial parasites. hydroxychloroquine appears to concentrate in food vacuoles of affected protozoa. it inhibits plasmodial heme polymerase. (from gilman et al., goodman and gilman's the pharmacological basis of therapeutics, 9th ed, p970)
  • Iodoquinol

    one of the halogenated 8-quinolinols widely used as an intestinal antiseptic, especially as an antiamebic agent. it is also used topically in other infections and may cause cns and eye damage. it is known by very many similar trade names world-wide.
  • Itraconazole

    a triazole antifungal agent that inhibits cytochrome p-450-dependent enzymes required for ergosterol synthesis.
  • Diatrizoate Meglumine

    a versatile contrast medium used for diagnostic x-ray radiology.
  • Iothalamate Meglumine

    a radiopaque medium used for urography, angiography, venography, and myelography. it is highly viscous and binds to plasma proteins.
  • Ioxaglic Acid

    a low-osmolar, ionic contrast medium used in various radiographic procedures.
  • Meglumine

    1-deoxy-1-(methylamino)-d-glucitol. a derivative of sorbitol in which the hydroxyl group in position 1 is replaced by a methylamino group. often used in conjunction with iodinated organic compounds as contrast medium.
  • Meglumine Antimoniate

    antimony salt of meglumine that is used in the treatment of leishmaniasis.
  • Metronidazole

    a nitroimidazole used to treat amebiasis; vaginitis; trichomonas infections; giardiasis; anaerobic bacteria; and treponemal infections.
  • Nalidixic Acid

    a synthetic 1,8-naphthyridine antimicrobial agent with a limited bacteriocidal spectrum. it is an inhibitor of the a subunit of bacterial dna gyrase.
  • Nifuratel

    local antiprotozoal and antifungal agent that may also be given orally.
  • Nitrofurantoin

    a urinary anti-infective agent effective against most gram-positive and gram-negative organisms. although sulfonamides and antibiotics are usually the agents of choice for urinary tract infections, nitrofurantoin is widely used for prophylaxis and long-term suppression.
  • Oxolinic Acid

    synthetic antimicrobial related to nalidixic acid and used in urinary tract infections.
  • Pefloxacin

    a synthetic broad-spectrum fluoroquinolone antibacterial agent active against most gram-negative and gram-positive bacteria.
  • Pipemidic Acid

    antimicrobial against gram negative and some gram positive bacteria. it is protein bound and concentrated in bile and urine and used for gastrointestinal, biliary, and urinary infections.
  • Piromidic Acid

    antibacterial against mainly gram negative organisms. it is used for urinary tract and intestinal infections.
  • Trimethoprim

    a pyrimidine inhibitor of dihydrofolate reductase, it is an antibacterial related to pyrimethamine. it is potentiated by sulfonamides and the trimethoprim, sulfamethoxazole drug combination is the form most often used. it is sometimes used alone as an antimalarial. trimethoprim resistance has been reported.
  • Trimethoprim Resistance

    nonsusceptibility of bacteria to the action of trimethoprim.
  • Trimethoprim, Sulfamethoxazole Drug Combination

    a drug combination with broad-spectrum antibacterial activity against both gram-positive and gram-negative organisms. it is effective in the treatment of many infections, including pneumocystis pneumonia in aids.

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 other systemic anti-infectives and antiparasitics (T37). Use the following options for the aplicable episode of care:

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

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

  • Unacceptable principal diagnosis - There are selected codes that describe a circumstance which influences an individual's health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis.

Present on Admission (POA)

T37.8X6S 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.

Table of Drugs and Chemicals

The parent code T37.8X6 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.

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?

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
