Hello- i’m trying without much luck to find any guidelines on how to code when a provider documents "hypertension due to diabetes" I know that DM and HTN do not have a causal relationship and there are no combination codes to link them together.

One resource (see below) I found says you would code the E11- DM dx with the I15.2 hypertension secondary to endocrine disorders as 2ndary- I have not been able to find any other supporting documentation for this coding suggestion.

curious if anyone else has any input?
