Poisoning by cardi-stim glycos/drug simlar act, undet, init

This code signifies an accidental or intentional overdose or adverse reaction to cardiac glycosides or similar medications, where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined at the time of initial assessment. These drugs primarily affect heart muscle contraction.

Apply this code when a patient presents with symptoms of poisoning from medications like digoxin, and the provider's documentation does not specify whether the poisoning was accidental, intentional, or due to therapeutic error. This is for the initial encounter for treatment of the poisoning.

• Requires additional codes for manifestations of the poisoning.
• Do not use if the intent of the poisoning is clearly documented (e.g., accidental, intentional self-harm).
• Remember the 7th character 'A' for initial encounter; subsequent care would use 'D' or 'S'.
