Poisn by cardi-stim glycos/drug simlar act, undet, sequela

This code signifies a long-term health condition or complication resulting from an unconfirmed or unknown exposure to cardiac-stimulant glycosides or similar acting drugs. The original poisoning event's intent (accidental, intentional self-harm, assault) could not be determined. This code is used when the acute phase of the poisoning has passed, and residual effects are being treated.

Apply this code when documenting a patient presenting with a chronic or residual effect directly attributable to a past poisoning by cardiac glycosides, where the circumstances of the original poisoning remain unclear. Examples include persistent arrhythmias, neurological deficits, or organ damage that developed after an undetermined exposure to digoxin or related substances. This code is appropriate for follow-up care related to such sequelae.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past, undetermined cardiac glycoside poisoning.
• Do not use for acute poisoning events; refer to the appropriate acute poisoning codes (T46.0X1-T46.0X4) for initial encounters.
