Wiki Revenue code 250 vs 636

[dvoegele]

Can anyone out there tell me the real difference between these two, I have read the guidelines but still unsure when to use the 250 versus the 636,
My guess is to use 636 for injectables and the 250 po

You should assign revenue code 637 to Self administered drugs to differentiate them from drugs covered under revenue code 250.
