Thread: In complete colonoscopies

  1. #11

    First, I need to know, does the physician intend to repeat the colonoscopy at a later date? (after a better prep)

    If yes, then code the procedure as incomplete with a -53 modifier so that you can bill for the second colonoscopy.

    Second, if your physician is not going to repeat the colonosopy, how far was the scope advanced? If he/she passed the scope beyond the Splenic Flexure than you bill the procedure as complete. (using the -52 modifier is optional, as long as the scope was passed beyond the Splenic flexure you can bill the procedure as complete.)

    Default incomplete visual colonoscopy

    How would you icd-9 code incomplete visual colonoscopy?

    I was taught that 52 is for poor prep and 53 is for patient not tolerating the procedure.

    Here is a great link:

    Mod 53 is used for incomplete for Medicare and other carriers but Mod 52 is used for Medicaid.
