Type 1 diabetes mellitus with other skin ulcer

This code signifies a patient diagnosed with Type 1 diabetes who also presents with a skin ulcer that is not specifically a diabetic foot ulcer. This ulcer could be located anywhere on the body other than the foot, and its presence is directly attributable to the patient's diabetic condition.

Use this code when documentation clearly states Type 1 diabetes and an "other" skin ulcer, meaning not a foot ulcer, and the ulcer is a complication of the diabetes. This applies to ulcers on the lower leg, thigh, trunk, or upper extremities, provided they are diabetic in origin. Documentation should specify the type of diabetes and the anatomical location of the ulcer.

• Always ensure the documentation explicitly links the skin ulcer to the Type 1 diabetes.
• Do not use this code for diabetic foot ulcers; those have specific codes (E10.621-).
• Code the specific type and location of the skin ulcer as an additional diagnosis if further detail is available (e.g., pressure ulcer, venous stasis ulcer).
