973.0 — Poisoning by antacids and antigastric secretion drugs
About ICD-9-CM 973.0
973.0 is an ICD-9-CM diagnosis code for poisoning by antacids and antigastric secretion drugs. 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 8 ICD-10-CM codes, such as T47.0X1A (Poisoning by histamine H2-receptor blockers, accidental (unintentional), initial encounter), T47.0X2A (Poisoning by histamine H2-receptor blockers, intentional self-harm, initial encounter) and T47.0X3A (Poisoning by histamine H2-receptor blockers, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
