Poisoning by expectorants, undetermined, initial encounter

This code signifies an adverse event resulting from an expectorant medication, where the intent of the exposure is unknown. It indicates the patient is in the acute phase of treatment for the poisoning.

Apply this code when a patient presents with symptoms of poisoning from an expectorant, and the healthcare provider cannot determine if the exposure was accidental, intentional self-harm, or assault. This is specifically for the initial visit or encounter for this particular poisoning event.

• Ensure documentation clearly states "undetermined" intent for expectorant poisoning.
• Always assign a secondary code for the specific expectorant if known, or a code for the adverse effect if applicable.
• Do not use this code for adverse effects of correctly prescribed and administered expectorants; use codes from the T36-T50 range with the appropriate 5th or 6th character for adverse effect.
