Poisoning by unsp hormones and synthetic sub, undet, sequela

This code indicates a long-term consequence or residual effect resulting from a poisoning event involving an unspecified hormone or synthetic substitute. The original poisoning's intent (accidental, intentional self-harm, assault, undetermined) could not be established. The "sequela" aspect means the acute poisoning has resolved, but lasting health problems persist.

Use this code when documenting a chronic condition or permanent injury directly attributable to a past poisoning by an unknown hormone or synthetic substitute, and the intent of the poisoning remains undetermined. This applies to situations where the patient is no longer experiencing the acute effects of the poisoning but is being treated for its long-term complications.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., organ damage, neurological deficit).
• Ensure documentation clearly links the current condition to a past undetermined poisoning by an unspecified hormone.
• Avoid using this code for acute poisoning events; instead, use the appropriate acute poisoning code with the 7th character "A" or "D."
