Adverse effect of nonopioid analges/antipyret, NEC, subs

This code indicates a patient is experiencing an undesirable or harmful reaction to a non-opioid pain reliever or fever reducer that is not specifically categorized elsewhere, and this reaction is being managed during a follow-up visit. It signifies that the initial treatment for the adverse effect has already begun.

Use this code when documenting a subsequent encounter for a patient being treated for an adverse reaction to medications like NSAIDs (e.g., ibuprofen, naproxen) or acetaminophen, where the specific adverse effect is not detailed by a more precise code. This applies to ongoing management, monitoring, or follow-up care related to the drug reaction.

• Always sequence the code for the specific adverse effect (e.g., gastritis, rash) first, followed by this code.
• Ensure the documentation clearly states the encounter is for ongoing management of the adverse effect, not the initial presentation.
• Verify the medication involved is a non-opioid analgesic or antipyretic not covered by more specific T39 subcategories.
