ICD-10-CM

Table of Drugs and Chemicals — N

Find the substance, then read across to the column that matches what happened. The same substance produces a different code for an accidental poisoning, a deliberate one, an adverse effect from a correctly-administered drug, and underdosing. 258 substances beginning with N.

A blank cell means the column does not apply to that substance — not that the code is missing.
