Diabetic visits

I work for a podiatrist and a good portion of our patients are diabetics. I was told that when using the any diabetes code (E11.9, E10.9, E13.9, etc) the pain codes were necessary to be paid. Ive been seeing lately that its not necessary. Does anyone know the rule of thumb about this?

re: Diabetic visits

If you look at the Coding Notes and ICD-10-CM guidelines nothing says you must code a pain code.

You do however need to code any complications due to diabetes; there are many codes with ICD-10-CM that are used to fully describe a condition. For example
E11.621 - Type 2 diabetes mellitus with foot ulcer, in this case, you also need to code the site of the ulcer. Using Find-a-code you can have all of this information at your fingertips on the code information page. The key is having access to the rules and guidelines for ICD-10-CM.

When reporting Diabetes you also need to use an additional code to identify control
using insulin (Z79.4)
oral antidiabetic drugs (Z79.84)
oral hypoglycemic drugs (Z79.84)
