Table of Drugs and Chemicals: Substances Starting With E ICD-10-CM
The letter E section of the FY 2027 Table of Drugs and Chemicals covers 305 substance entries under 211 top-level substances. Each row carries up to six ICD-10-CM codes, one per intent column, and sub-entries are indented under their parent exactly as the printed CMS table nests them.
Table of Drugs and Chemicals: E 305 entries
Indented rows are sub-entries of the entry above them. The filter matches the full path, so typing a parent term finds its sub-entries too.
Questions About This Page
How do I read a row of this table?
Find the substance, then take the code from the column matching the documented intent. The codes are T-code stems; the code page adds the encounter 7th character (A, D, or S) and confirms billability.
Why do some substances have empty columns?
Not every substance has a code for every intent. An empty cell means the classification does not provide one, and the parent entry or the classification entries such as drug NEC apply.
