We now assume a relationship between certain conditions and diabetes if they are listed under "diabetes with" in icd10. Under "diabetes with" glaucoma is not listed however opthalmic complication is listed. Which gives you code E11.39. When you look up E11.39 in the tabular it instructs you to use the additional code for glaucoma. So why is my auditor and coding clinic telling me that glaucoma is not one of the conditions to assume is related to diabetes. I believe it is, but it is being referred to as "opthalmic complication" and not specifically glaucoma. All of my internet research is leading me to this code selection as well.
