    Question Elevated D-Dimer

    AAPC: Back to School
    Is an elevated D-Dimer enough to establish medical necessity for a venous doppler and is there an ICD-9 code for it? Thank you. Judy Perkins, Lubbock, Texas.

    The ICD-9 code is 790.99, but I don't think it's a covered DX for dopplers for medicare. I use that DX quite often. Sometimes that's the only indication for the test they give me so I have to use it.

    You should check the Medicare LCD list #L28254 for the list of ICD-9 codes that support medical necessity. I live in California and 790.99 is not on our LCD list. Check with your local Medicare carrier as this may be different for some regions.
