Poisn by unsp nonopi analgs/antipyr/antirheu, undet, subs

This code indicates a poisoning event involving an unknown non-opioid pain reliever, fever reducer, or anti-inflammatory medication, where the intent (accidental, intentional self-harm, assault) cannot be determined. This specific code is used for follow-up care after the initial treatment of the poisoning.

Use this code for patients presenting for follow-up appointments, monitoring, or management of residual effects from a previous poisoning by an unspecified non-opioid analgesic, antipyretic, or antirheumatic. This applies when the circumstances surrounding the poisoning remain unclear regarding intent.

• Ensure documentation clearly states "undetermined" intent for the poisoning.
• Verify this is a subsequent encounter; initial encounters would use the "A" seventh character.
• Confirm the substance is documented as an unspecified non-opioid analgesic, antipyretic, or antirheumatic.
