E86 (Volume depletion) compared with T83.091A (Other mechanical complication of indwelling urethral catheter, initial encounter), from the official CMS tabular data. Both may be reported when both conditions are documented (Excludes2).
Distinct conditions — both may be reported.
“disorders of fluid and electrolyte imbalance (E86-E87)”
An Excludes2 note means the excluded condition is not part of the code above it, but a patient can have both. Report both when both are documented.
