    Default Radiology dx for elevated D-dimer

    AAPC: Back to School
    I see quite a few CTA chest scans with a history stated as 'elevated D-dimer.' We have a difference in opinion in our office as to which code to use for this. I was previously advised to use 289.89 as this indicates a blood 'disorder' because it shows that there is breakdown of a thrombus somewhere in the body. The other side of the argument is to use 790.92 for abnormal coagulation profile. Any advice on which way to go with this? Thanks!!

    I always use 790.5 abnormal enzymes, serum NEC. But I try to find a code for patient symtoms to use first.

    I also use the 790.99 on the d-dimer for CTA's and I know that in our section of the world that it is not covered by MCR.
