I think ICD-10 has gone well too. My only concern is when I code for something like acute otitis media. Obviously, there should be laterality or bilaterality.
Acute right otitis media is H66.91, left is 92, bilateral is 93.
But, you can enter acute otitis media which is 90. It is green and, therefore, a billable code. But, would the insurance company say it should be more granular?
The other weird thing is the "acute otitis media" is H66.90 while chronic otitis media is H66.90. They seem completely opposite.
