I have a provider who did an EGD and Colonoscopy on at 26 year old with commercial insurance. No findings. Her indications state the JPS with a dx code of K63.5. That would do for the colonoscopy (or is the D12.6 supposed to be used like with the case of Familial Polyposis?) but what about the EGD? Do I use a K31.89 in this instance? I looked in the ICD 10 code book under Polyposis, Polyps, Syndromes and am not sure what to use. Any help would be appreciated.
