coding peripheral atherosclerosis

Date: Dec 13, 2018

Question:

When coding diagnoses for peripheral atherosclerosis, should I code all pertinent diagnosis (like in diabetes), or just the highest level of severity? For example, patient has claudication with rest pain (I70.221), but also a nonhealing ulcer of the toe (I70.235, L97.519). Should I code all three diagnoses, or just the ones pertaining to the ulcer?
