Hi,

May we substitute 11572-5 (Rheumatoid factor [Units/volume] in Serum or Plasma) for 15205-8? I have no labs mapped to the latter.

Thanks,

Ken

Ken,

Yes, it is ok to use 11572-5 (Rheumatoid factor [Units/volume] in Serum or Plasma) for 15205-8.

for 3.2.3. RA_COD_DX_PsoriaticArthritis we need a clarification as there is discrepancy between ...codes.csv file & alg.doc

 -- for ICD9, do we inc. all codes starting w/ 696 or just 696 (we only have 1 subj w/ 696 vs. 28

 -- for ICD10, do we inc. all codes starting w/ L40 or just the L40.5* codes listed in the ...codes.csv file?

thanks, 

Jen

Hi Jen,

The code list file is correct.  I updated the implementation documentation to correspond to the code list document.

The correct ICD9 is 696.0 and the ICD10 is L40.5*.

perfect, I will update my code & get you our data today or tomorrow.
