Adverse effect of nonopioid analges/antipyret, NEC, init

This code signifies an undesirable or harmful reaction experienced by a patient due to the therapeutic use of a non-opioid analgesic or antipyretic medication that is not specifically categorized elsewhere. This reaction occurred during the initial period of treatment for the adverse effect.

Apply this code when a patient presents with symptoms such as gastrointestinal upset, rash, or dizziness directly attributable to a medication like ibuprofen, naproxen, or acetaminophen, and the specific adverse effect is not covered by a more precise ICD-10-CM code. This is appropriate for the first time the patient is seen for this particular adverse event.

• Always sequence this code after the code for the specific manifestation of the adverse effect.
• Ensure the medication involved is a non-opioid analgesic or antipyretic and not otherwise specified.
• Verify that this is indeed the initial encounter for the adverse effect, not a subsequent or sequela encounter.
