2025 ICD-10-CM code T46.5X3S
Poisoning by other antihypertensive drugs, assault, sequela.
Medical necessity is established by the documented link between the assault/poisoning incident and the subsequent long-term health consequences.
- Injury, poisoning and certain other consequences of external causes (S00-T88)
- Injury, poisoning and certain other consequences of external causes (T07-T88) Poisoning by, adverse effects of and underdosing of drugs, medicaments and biological substances (T36-T50)
In simple words: This code indicates a long-term health problem that is the result of a past assault involving poisoning with antihypertensive medication (other than beta-blockers, calcium channel blockers, or diuretics).
This code represents a sequela (late effect) resulting from poisoning by antihypertensive drugs, due to an assault. It excludes poisoning by beta-adrenoreceptor antagonists (T44.7), calcium-channel blockers (T46.1), and diuretics (T50.0-T50.2).
Example 1: A patient was assaulted and forcibly given an overdose of an antihypertensive medication (other than a beta-blocker, calcium channel blocker, or diuretic). They survived the initial poisoning but now experience chronic kidney disease as a direct result of the incident., A victim of a robbery was unknowingly given a poisoned drink containing antihypertensive drugs (excluding specified types). Though they recovered from the acute poisoning, they now suffer from persistent neurological deficits., A person was attacked and injected with an unknown substance later identified as an antihypertensive drug (not a beta-blocker, calcium channel blocker, or diuretic). They experience long-term cardiac issues as a sequela of the poisoning.
Documentation should clearly indicate the specific antihypertensive drug involved (if known), evidence of the assault, and the long-term health consequences experienced as a direct result of the poisoning. Any related medical conditions or symptoms contributing to the sequela should also be documented.

- Place of Service:Inpatient Hospital, Emergency Room - Hospital, Other Place of Service (e.g., physician's office for follow-up care)
