Ask Dr. Z

Seeing patients with advanced vascular disease we run into patients with multiple diagnoses outside of the vascular specialty. Once we report the E&M code and determine the appropriate principal vascular code(s), is there a benefit to submitting additional non-specialty vascular codes such as ring worm or diverticulitis (etc.) when submitting a claim? Is there anything lost or anything gained by including diagnosis codes that are outside the vascular specialty when submitting claims?
