Poisoning by antipruritics, accidental (unintentional), subs

This code signifies an accidental or unintentional poisoning specifically due to an antipruritic medication. The "subsequent encounter" designation indicates that the patient is receiving follow-up care for the poisoning, such as monitoring, continued treatment, or evaluation of residual effects, after the initial acute phase.

Apply this code when a patient presents for follow-up care related to an accidental overdose or ingestion of anantipruritic agent. This includes scenarios where the patient is being monitored for adverse reactions, undergoing detoxification, or receiving treatment for complications arising from the poisoning.

• Ensure the documentation clearly states the poisoning was accidental and caused by an antipruritic.
• Verify the encounter is for follow-up care, not the initial acute treatment, to justify the "D" seventh character.
• Always code the specific antipruritic drug if known, using an additional T-code from the T36-T50 range.
