Advrs effect of unsp nonopi analgs/antipyr/antirheu, sequela

This code signifies a long-term or residual condition resulting from an adverse reaction to a nonopioid pain reliever, fever reducer, or anti-inflammatory medication where the specific drug is not documented. It indicates that the initial adverse effect has resolved, but a lasting health problem remains.

Use this code for patients presenting with a chronic or permanent sequela directly attributed to a past adverse drug event involving an unspecified nonopioid analgesic, antipyretic, or antirheumatic. This is appropriate when the original adverse effect has passed its acute phase, and the current encounter addresses the persistent complication.

• Always attempt to identify the specific drug involved for a more precise code.
• Requires a seventh character "S" to denote sequela, indicating the residual effect of a past adverse event.
• Do not use for acute adverse effects; those would typically use an "A" or "D" seventh character.
