Intolerance is now a medical condition?

I am currently working with medical data at my work.  Sprinkled among that data are Medicare/Medicaid codes of various conditions, that have now become rather standard in the medical industry.  As I checked up on my list of extracted codes, I noticed this one:

SNM:102461004    increased intolerance    CODE

It seems now that increased intolerance is now something diagnosable.  I wonder what treatments are available for hate?

Actually, I have a funny feeling that here, "increased intolerance" means "we're giving the guy the medicine, but it's not working as effective as before" rather than "yeah, I used to like hippies, but you know, they've been getting on my nerves lately".  :-)
