Unspecified adverse effect of drug or medicament

    2016 2017 2018 2019 2020 Non-Billable/Non-Specific Code
  • T88.7 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
  • The 2020 edition of ICD-10-CM T88.7 became effective on October 1, 2019.
  • This is the American ICD-10-CM version of T88.7 - other international versions of ICD-10 T88.7 may differ.
Applicable To
  • Drug hypersensitivity NOS
  • Drug reaction NOS

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.

Clinical Information
  • Acute or chronic and often undesirable effects of drugs occurring in addition to the intended or therapeutic objective.
  • All noxious and unintended responses to a medicinal product related to any dose should be considered adverse drug reactions (from us fda 'guideline for industry, clinical safety data management: definitions and standards for expedited reporting').
  • An allergy to a pharmaceutical product.
  • Immunologically mediated adverse reactions to medicinal substances used legally or illegally.
  • Most of the time, medicines make our lives better. They reduce aches and pains, fight infections, and control problems such as high blood pressure or diabetes. But medicines can also cause unwanted reactions.one problem is interactions, which may occur between
    • two drugs, such as aspirin and blood thinners
    • drugs and food, such as statins and grapefruit
    • drugs and supplements, such as gingko and blood thinners
    • drugs and diseases, such as aspirin and peptic ulcers
    interactions can change the actions of one or both drugs. The drugs might not work, or you could get side effects.side effects are unwanted effects caused by the drugs. Most are mild, such as a stomach aches or drowsiness, and go away after you stop taking the drug. Others can be more serious.drug allergies are another type of reaction. They can be mild or life-threatening. Skin reactions, such as hives and rashes, are the most common type.when you start a new prescription or over-the-counter medication, make sure you understand how to take it correctly. Know which other medications and foods you need to avoid. Ask your healthcare provider or pharmacist if you have questions.
  • Unintended, deleterious effects of otherwise licit, therapeutic, properly administered drugs; for effects of illicit and abused drugs, or of environmental chemicals, see toxicology or poisoning.
