I did not mean to imply that corrections are not appropriate.
However, as an HCC coder myself - you must exercise extreme caution in "correcting" notes so that you are not appearing to be make a note fit an HCC catagory.
Medicare can, and does, audit submitted HCC's and you are required to send them documentation supporting the HCC submitted.
All I am saying, is addending a note is ok, but it should never be common practice and it should most certainly not exaggerate a patient's true issue just to make it fall into an HCC.
For example, do not diagnose impaired fasting BG as Diabetes because DM is an HCC and impaired fasting blood glucose is not covered.
The coder should also never make a leap in coding, either. If the patient has diabetes and chronic kidney disease, do not code to HCC 15 unless the physician has linked the CKD directly to the DM.
It's the coders name and credential on the line, and it's a lot of money at stake.
