About ICD-9-CM E873.8
E873.8 is an ICD-9-CM diagnosis code for other specified failure in dosage. 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 2 ICD-10-CM codes, such as Y63.6 (Underdosing and nonadministration of necessary drug, medicament or biological substance) and Y63.8 (Failure in dosage during other surgical and medical care). All of these are approximate matches, so review the record to pick the right one.
