vs Disorder of liver, NOS

In general, coding abnormal laboratory findings is optional when the specific cause is known and coded.
In the absence of knowing the specific cause, the choice of using the code for abnormal lab test versus a nonspecific diagnosis code (e.g. Disorder of liver, NOS) should mainly be guided by whether or not the other coded diagnoses are present.
- Example: COVID is associated with elevated LFTs in about 30% of cases. Thus if that is the only recognized reason for the elevated LFTs, then it makes most sense to code and link the COVID diagnosis and the abnormal labs together (instead of using the Disorder of liver, NOS code).

Abnormal test

This code identifies an abnormal test result, not a disorder.
- The preference is to code the cause of the abnormal test, if known.
- also coding this abnormal test, along with the cause is optional however, it is not necessary.
- When the DX is not known, code likely related other tests and signs and symptoms as Combined ICD10 codes; some likely ones might be listed in #Candidate Combined ICD10 codes.

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.

Example:

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.
