E13 vs E87.0
E13 (Other specified diabetes mellitus) compared with E87.0 (Hyperosmolality and hypernatremia), from the official CMS tabular data. Both may be reported when both conditions are documented (Excludes2).
Can these codes be reported together?
Yes, when both are documented. E87.0 carries an Excludes2 note covering E13: “diabetes with hyperosmolarity (E08, E09, E11, E13 with final characters .00 or .01)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
