I’m using E86.0 Dyhydration, notation states, Use additional code(s) for any associated disorders of electrolyte and acid-base balance (E87.-).
Provider did not state anything in his notes however, lab report shows K is high, do I code for E87.5 Hyperkalemia?

I’m torn on this because guideline states that I (the coder) cannot interpret a diagnosis using lab reports.

Your thoughts are very much appreciated.
