2024 ICD-10-CM Diagnosis Code T50.901
Poisoning by unspecified drugs, medicaments and biological substances, accidental (unintentional)
- ICD-10-CM Code:
- T50.901
- ICD-10 Code for:
- Poisoning by unsp drug/meds/biol subst, accidental
- Is Billable?
- Not Valid for Submission
- Code Navigator:
T50.901 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of poisoning by unspecified drugs, medicaments and biological substances, accidental (unintentional). 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.
Unspecified diagnosis codes like T50.901 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
Specific Coding Applicable to Poisoning by unsp drug/meds/biol subst, accidental
Non-specific codes like T50.901 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 poisoning by unsp drug/meds/biol subst, accidental:

Clinical Information
Laminaria
a genus of brown algae in the family laminariaceae. dried pencil-like pieces may be inserted in the cervix where they swell as they absorb moisture, serving as osmotic dilators.Saccharin
flavoring agent and non-nutritive sweetener.1,4-alpha-Glucan Branching Enzyme
in glycogen or amylopectin synthesis, the enzyme that catalyzes the transfer of a segment of a 1,4-alpha-glucan chain to a primary hydroxy group in a similar glucan chain. ec 2.4.1.18.Electrophoresis, Starch Gel
electrophoresis in which a starch gel (a mixture of amylose and amylopectin) is used as the diffusion medium.Hydroxyethyl Starch Derivatives
starches that have been chemically modified so that a percentage of oh groups are substituted with 2-hydroxyethyl ether groups.Starch
any of a group of polysaccharides of the general formula (c6-h10-o5)n, composed of a long-chain polymer of glucose in the form of amylose and amylopectin. it is the chief storage form of energy reserve (carbohydrates) in plants.Starch Phosphorylase
an enzyme of the phosphorylases family that catalyzes the degradation of starch, a mixture of unbranched amylose and branched amylopectin compounds. this phosphorylase from plants is the counterpart of glycogen phosphorylase in animals that catalyzes the reaction of inorganic phosphate on the terminal alpha-1,4-glycosidic bond at the non-reducing end of glucans resulting in the release of glucose-1-phosphate.Starch Synthase
an enzyme that catalyzes the transfer of glucose from adpglucose to glucose-containing polysaccharides in 1,4-alpha-linkages. ec 2.4.1.21.Toxic Optic Neuropathy
damage to the eye or its function (e.g., visual impairment) due to optic nerve damage secondary to toxic substances such as drugs used in chemotherapy; immunotherapy; or radiation.
Coding Guidelines
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 diuretics and other and unspecified drugs, medicaments and biological substances (T50). 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
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?
