Oth diabetes mellitus with other skin complications

This code signifies a form of diabetes mellitus, not otherwise classified as type 1 or type 2, that is complicated by skin manifestations other than those specifically listed elsewhere (e.g., foot ulcer, gangrene). These skin complications are directly attributable to the patient's diabetes.

Apply this code when documentation specifies "other specified diabetes mellitus" and details a diabetic-related skin condition such as diabetic dermopathy, necrobiosis lipoidica diabeticorum, or eruptive xanthomatosis, provided these are not already covered by more specific codes. The physician's notes should clearly link the skin condition to the patient's diabetes.

• Always sequence the diabetes code first, followed by a code for the specific skin complication if one exists.
• Ensure the documentation explicitly states "other specified diabetes mellitus" or provides sufficient detail to rule out type 1, type 2, or drug/chemical induced diabetes.
• Do not use this code for diabetic foot ulcers (E13.621) or diabetic gangrene (E13.622), as more specific codes are available.
