    Default Colonoscopy

    We are doing a routine colon on a patient because they have metastatic neuro endocrine tumor and we are trying to r/o primary gi tract. How would you dx code this?

    Code the secondary neoplasm first, then use 199.1 for the primary, since that is the unknown.

    Wouldn't you use a V-code first since it is being ruled out and not as of yet confirmed?

    Do not use 199.1 for the unknown primary.
    With a neuroendocrine tumor use 209.20. The met will also be a code from the 209.7* category.
    As for the V code... it would depend on if it was ordered/documented as a screening or a diagnostic colonoscopy.
