    Unhappy photo patch test

    AAPC: Back to School
    What is the correct coding for a Photo Patch Test?

    The first day the pt's back is exposed to UVA

    The second day two sets of patches are applies with UVA - cpt 95052 x #units

    The third one set of patches are exposed to UVA

    The forth day the patches are read no documentation(usually code 99024)?

    The fifth day the final read with diagnosis - appropriate E&M and ICD-9

    Please advise,
    Thank you!

    Default Photo patch test

    Thank you, but I already saw that and it didn't help because the pt is exposed to UVA one day, 2 identical sets of patches are put on the second day. The third day only 1 set is exposed to the UVA. then they look at it two more times before giving a dx.

    Sorry, thought it could help.

    Thiis how we handle simple patch test visits with no UVA...
    We code an e/m on the first visit when the doctor decides to use the patch.
    Sometimes the patch is placed then so we charge but if a visit is a Thursday or Friday the patient returns and has the patch placed and only the patch is charge no e/m.
    The return visit with nurse is coded with 99211 unless a physician needs to see patient.
    The final visit is billed when the provider discusses the results to the patient.
    I hope that helps

    Default photo patch test?

    Thank you for you response. I still need to know how to code the test when UVA is involved (Photo Patch Test).
