Type 2 diabetes mellitus with other skin ulcer

This code signifies a patient diagnosed with type 2 diabetes mellitus who also presents with a skin ulcer that is not a diabetic foot ulcer. This condition often arises from compromised circulation, neuropathy, or impaired wound healing mechanisms secondary to chronic hyperglycemia, affecting areas other than the foot.

Use this code when documentation clearly indicates type 2 diabetes and a non-foot skin ulcer, such as a decubitus ulcer, venous stasis ulcer, or arterial ulcer, where the diabetes is a contributing factor. Supporting documentation should specify the type of diabetes and the location and nature of the skin ulcer, confirming it's not on the foot.

• Always code the specific type of skin ulcer (e.g., L89.- for pressure ulcer, I83.0- for varicose veins with ulcer) as a secondary diagnosis.
• Ensure the documentation explicitly links the diabetes to the skin ulcer, even if it's not a classic diabetic foot ulcer.
• Do not use this code for diabetic foot ulcers; those have specific codes within the E11.621- series.
