Repeated events

If this happens repeatedly during the same ward or unit stay, only code it the first time it happens, regardless of whether it is an Admit Diagnosis or Acquired Diagnosis, rather than each time it happens. See ICD10 codes only coded the first time for other diagnoses coded this way.

ExpandExample:

A person has a self-limited episode of A-fib. It goes away and then recurs. Only code the first one. A person has a self-limited episode of A-fib. It goes away but then he has an episode of V-tach. As this is a different diagnosis, both of these should be listed, but only code once each. Patient comes in with hypokalemia. It’s treated and remits, but the next day it recurs. Only code the first time.

Additional Info

• The parameter for coding hyperkalemia is the following: (This change is active as of Feb 27,2025)
  • K+ >=6.0
• Main signs and symptoms of hyperkalemia are:
  • cardiovascular - conduction abnormalities, ECG changes * V-fib, asystole
  • ECG changes: tented T's * wide QRS; long PR * small, wide P's, sine wave
  • neuromuscular - weakness, paresthesias * flaccid paralysis
• If it's due to a drug effect, then code that also (see the 2 lists below).

Alternate ICD10s to consider coding instead or in addition

• Disorder of mineral metabolism, NOS
• Electrolyte disorder, NOS

Candidate Combined ICD10 codes

• If the cause of this diagnosis is known, combine it with this code.
