Poisoning vs Adverse Effects of Drugs ICD-10-CM Coding


In this course, participants will delve into the intricate world of medical coding, focusing on the differentiation between poisoning, adverse effects of drugs, underdosing, and toxic effects as defined by the ICD-10-CM coding system. Through detailed explanations and real-life scenarios, this course explores the official guidelines for coding and reporting in this domain. Students will gain a comprehensive understanding of medication purposes, dosages, categories of medication effects, and the critical factors that determine proper medication administration.

Included Lessons:

  • Medication Purpose
  • Medication Dosages
  • Categories of Medication Effects
  • Adverse Effects
  • Poisoning
  • Underdosing
  • Toxic Effects
  • Coding Information and Coding Clinics Pertaining to Poisoning vs Adverse Effect

Key Takeaways 

Overall, completing this course equips medical coders with the knowledge and skills necessary to accurately code and document cases related to medication effects, ultimately contributing to more precise and effective healthcare record-keeping. Some key takeaways include: 
  • Understanding Medication Purposes: Participants will gain a deep understanding of why medications are prescribed and the various purposes they serve in healthcare, such as symptom relief, disease management, and pain control.
  • Medication Dosages: Coders will learn how to interpret medication dosages, both for over-the-counter and prescription drugs, ensuring they can accurately assess whether a patient is following the prescribed regimen.
  • Categories of Medication Effects: Students will become proficient in categorizing medication effects into poisoning, adverse effects, and underdosing, enabling them to make precise coding decisions based on patient documentation.
  • Proper Medication Administration: Coders will develop the ability to determine whether a patient has taken medication correctly, considering factors such as dosage, frequency, and adherence to prescription instructions.
  • ICD-10-CM Guidelines: Participants will become well-versed in the official guidelines for coding and reporting related to poisoning and adverse effects, ensuring compliance with coding standards.
  • Differentiating Adverse Effects and Poisoning: The course will equip coders with the knowledge to distinguish between adverse effects (when a patient takes a prescribed drug as directed but experiences unwanted side effects) and poisoning (when a patient takes a drug incorrectly or takes too much).
  • Intent Classification: Coders will learn how to classify the intent of poisoning cases, whether accidental, intentional self-harm, assault, or undetermined, and apply the appropriate codes accordingly.
  • Coding Scenarios: The course will include practical scenarios and examples that allow coders to practice their skills in coding for medication-related conditions, reinforcing their ability to apply the concepts in real-world situations.
  • Toxic Effects: Coders will understand how to code for toxic effects when a patient encounters harmful substances, broadening their knowledge of adverse events.

What is the difference between poisoning and adverse effects of drugs in medical coding?
In medical coding, poisoning occurs when a patient takes too much of a medication (either intentionally or unintentionally) or takes a medication that wasn't prescribed to them. Adverse effects, on the other hand, happen when a patient experiences unwanted side effects or reactions from a drug taken as prescribed. The key distinction is whether the drug was taken correctly or incorrectly.
How do I determine the intent (accidental, intentional, assault, undetermined) in poisoning cases?
Determining intent is crucial in poisoning cases. Accidental intent means the ingestion was unintentional or due to carelessness. Intentional self-harm indicates the patient took the drug with the intent to harm themselves. Assault means someone administered the drug to harm another person. Undetermined intent is used when intent cannot be determined from the documentation in the record.
Can you provide tips for accurately coding medication-related scenarios?

Pay close attention to the patient's medication history, prescribed dosages, and how the medication was taken (correctly or incorrectly). Verify whether the medication was prescribed or not. Always follow the specific coding guidelines for poisoning, adverse effects, underdosing, and toxic effects in ICD-10-CM, and use intent categories when appropriate.
