About E87.7

E87.7 is the ICD-10-CM diagnosis code for fluid overload. It belongs to category E87 (other disorders of fluid, electrolyte and acid-base balance), block E70-E88 (metabolic disorders) and chapter 4 (endocrine, nutritional and metabolic diseases). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within E87 (other disorders of fluid, electrolyte and acid-base balance), E87.7 is specifically for fluid overload. Related codes cover Hyperosmolality and hypernatremia (E87.0), Hypo-osmolality and hyponatremia (E87.1), acidosis (E87.2), Alkalosis (E87.3), mixed disorder of acid-base balance (E87.4), Hyperkalemia (E87.5), Hypokalemia (E87.6) and other disorders of electrolyte and fluid balance, not elsewhere classified (E87.8).

To report this condition, pick the subcode that matches the documentation: E87.70 (unspecified), E87.71 (overload) and E87.79 (overload).

Don't report E87.7 together with the conditions in its Excludes1 note: edema NOS (R60.9) and fluid retention (R60.9).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
