ICD-9-CM diagnosis code (retired)
963.8 — Poisoning by other specified systemic agents
About ICD-9-CM 963.8
963.8 is an ICD-9-CM diagnosis code for poisoning by other specified systemic agents. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 4 ICD-10-CM codes, such as T45.8X1A (Poisoning by other primarily systemic and hematological agents, accidental (unintentional), initial encounter), T45.8X2A (Poisoning by other primarily systemic and hematological agents, intentional self-harm, initial encounter) and T45.8X3A (Poisoning by other primarily systemic and hematological agents, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
