Do I have to link my Quality Data Codes to a specific diagnosis code?

Yes!  This was a source of error for physicians who reported in 2007.  If the measure defines a specific diagnosis (chronic kidney disease, fracture, osteoporosis) then you must link your PQRI Quality Data Code (QDC) to the appropriate diagnosis on the claim form.

If the measure does not define a diagnosis code, you may submit any diagnosis with the claim.
