Adverse effect of nonopioid analges/antipyret, NEC, sequela

This code signifies a lasting health problem or condition that developed as a direct result of a past adverse reaction to a non-opioid pain reliever or fever reducer, excluding those specifically classified elsewhere. This adverse effect is no longer acute but has left a permanent or long-term consequence for the patient.

Use this code when documenting a chronic or residual condition, such as persistent organ damage (e.g., kidney damage, liver damage) or a permanent neurological deficit, that is directly attributable to a previous adverse drug reaction from a non-opioid analgesic or antipyretic. This applies when the acute adverse event has resolved, but its long-term effects remain.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic kidney disease).
• Ensure documentation clearly links the current chronic condition to a past adverse effect of a non-opioid analgesic or antipyretic.
• Do not use this code for acute adverse reactions; those would be coded with the appropriate acute T39.8X5A or T39.8X5D codes.
