Clinical notes

Excludes2 (not included here)

An Excludes2 note means the excluded condition is not part of this one, but a patient can have both at the same time — in that case both codes may be reported together.

  • drug-induced aplastic anemia (D61.1)

Use additional code

This code represents an underlying condition. When a related manifestation is also present, coding convention calls for an additional code to be listed after this one.

  • code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
