    Yes given what you have stated I would go with the 558.9.

    I agree with you both on using the 558.9.

    You could also add V12.79 (history of digestive disease) for the hx of UC as a secondary dx.

    And to speak to what Deb had educated me on in an earlier post, is this a follow-up exam/procedure based on the hx of UC? So also possibly use a V67.xx code.
