Poisoning by oth psychodysleptics, self-harm, subs

This code signifies a patient presenting for follow-up care after an intentional self-harm event involving poisoning by a hallucinogenic substance other than LSD. The initial acute treatment for the poisoning has already occurred, and the patient is now being seen for ongoing management related to this specific incident. This could include monitoring for residual effects, psychiatric evaluation, or further treatment for complications.

Apply this code when documenting a subsequent encounter for a patient who previously attempted self-harm by ingesting or administering a hallucinogen (e.g., psilocybin, MDMA, PCP, mescaline) and is now receiving follow-up care. This would be appropriate for visits such as a psychiatrist's follow-up after discharge from an emergency department, a primary care physician checking in on the patient's recovery, or a visit to manage ongoing physical symptoms related to the poisoning.

• Ensure the documentation clearly indicates "intentional self-harm" and that the substance was a "hallucinogen" (excluding LSD, which has its own specific code).
• Verify that this is a "subsequent encounter" and not the initial acute treatment phase; for initial encounters, a different encounter character would be used.
• Always code with an accompanying mental health diagnosis (e.g., depression, bipolar disorder) to fully capture the patient's condition, as the poisoning is often a manifestation of an underlying psychiatric issue.
